Answer:B. Their DNA molecules have different numbers of strands.

Explanation:that is chromosome that make them to differ in diploid numbers thus differ generally and appear differently

Answer 2
I disagree with the above answer. The answer should be D as the different nucleotide sequences would result in different proteins formed and synthesized that would eventually perform different functions and account the for the structural differences between the two species. While amount of DNA differ, it does not account for the vast differences observed.

why most
ecologists do not study the biosphere level of
organization.

Answers

Answer: Most ecologists do not study the biosphere level of organization because it is difficult to study all of life on earth as a whole. It is more effective to study it broken down into parts.

Explanation:

Final answer:

Ecologists typically do not study the biosphere level of organization due to its complexity, the vast amount of data required, and the resources needed to model such interactions. Instead, they focus on more manageable levels such as the organism, population, community, or ecosystem levels to gain insights into ecological processes.

Explanation:

Ecologists study organisms and their environments at different levels, from individual organisms to the whole biosphere. The biosphere is the most inclusive level, encompassing all organisms on Earth and the regions they inhabit. While it might seem comprehensive to focus on the biosphere level, most ecologists do not study at this level due to its immense complexity and scale. Issues like ocean pollution, air pollution, and global climate change are indeed investigated at the biosphere level, but these are often addressed through more specialized interdisciplinary fields such as environmental science, climatology, and global ecology.

Studying the biosphere inherently requires vast amounts of data and resources to accurately understand and model the interactions at play, which can be challenging to manage even with modern technology. Moreover, ecological phenomena at this level are influenced by a multitude of factors, including both biotic components (living species) and abiotic components (air, water, and soil). These factors combined with the dynamic nature of ecological systems make it difficult for ecologists primarily working in laboratories to conduct consistent and comprehensive research at the biosphere level without considerable investment in time and resources.

What aspect of the cell theory did Redi’s experiment support? Explain.

PLEASE EXPLAIN AND USE DETAILS FROM THE PASSAGE...

Answers

Answer:

All cells come from pre-existing cells.

Explanation:

Cell theory was proposed by MJ Schleiden , T.Schwann and Rudolf Virchow.Cell theory states that, all organisms are made up of cells, Cell is the structural and functional unit of life and Cells arise from pre-existing cells.In ancient time there was a concept of spontaneous existence of life.People believed that life arose from inorganic substances.But when Fransesco Redi observed that maggot arose on meat.He hypothesised that the maggot must have risen from fly egg.To confirm this hypothesis he set up an experiment in which  he kept meats in flasks; some open to air, some covered with gauge and some completely sealed.It was obvious that the sealed flask will not support life as it does not have air .The  flask covered with gauge proved that the concept of evolution of life from inorganic substance was wrong because the flask had all the inorganic elements that support life like air water light etc but no maggots grew in it.The open flask , in which the maggots grew proved that maggots arose from the eggs that were laid by the fly.Only the open flask had provisions for the fly to enter it and lay eggs. These eggs were the first cell of the maggot.Thus, Redi's Experiment supported the fact that cells arise from preexisting cells.

Answer:

The correct answer will be option- A and D

Explanation:

E.coli is a bacteria which is pathogenic to humans and E. histolytica is an amoeba which is a parasite.  Both are different species but both are single-celled organism which to survive share feature among them.

The common characters shared by these two species are: they depend on the source of energy for their survival which they usually get from the hosts. Both the species reproduce to produce progenies like them which help them maintain continuity of the species of Earth.

Thus, options- A and D are the correct answer.

Both Escherichia coli and Entamoeba histolytica are species of bacteria. They both depend on sources of energy or food and are also capable of reproducing. A and D are the right options.

Bacteria species, including E. coli and E. histolytical, are generally heterotrophic. In order words, they are not able to manufacture their own food but depend on external sources for their food or energy.

Both E. coli and E. histolytical are also capable of fulfilling the characteristics of living organisms, which include reproduction.

how can a person's genotype for a trait be determined from his or her phenotype for the trait? ​

Answers

Final answer:

A person's genotype for a trait can be determined from their phenotype by observing the principles of Mendelian inheritance. By understanding the relationship between dominant and recessive alleles, we can deduce the genotype of an individual based on their observable characteristics. However, it is important to consider that some traits are influenced by multiple genes and environmental factors.

Explanation:

The genotype of a person for a trait can be determined from their phenotype by understanding the principles of Mendelian inheritance. In Mendelian genetics, alleles for a specific trait can be dominant or recessive. By observing the phenotype of a person, such as their physical appearance or observable characteristics, we can infer their genotype.

For example, let's consider the trait of flower color in pea plants studied by Mendel. Purple flower color is dominant (represented by P) and white flower color is recessive (represented by p). If we observe a person with purple flowers, we can deduce that their genotype could be either PP or Pp, as both genotypes result in the dominant phenotype of purple flowers. However, if we observe a person with white flowers, their genotype must be homozygous recessive (pp) because the recessive phenotype only occurs when both alleles are recessive.

It is important to note that the relationship between genotype and phenotype is not always straightforward. Some traits are polygenic, meaning they are influenced by multiple genes, and can also be affected by environmental factors. In these cases, determining genotype solely based on phenotype can be more complex.

eggs are used in alot of baking goods eaten over thanksgiving. eggs only have one set of chromosomes. list three vocabulary words or terms that describe the number of chromosomes found in an egg.

Answers

The three vocabulary words or terms that describe the number of chromosomes found in an egg are are haploid, diploid and triploid.

Explanation:

Egg is a very common ingredient which is used a lot in baking goods like making of cakes and cookies. The egg has only one set of chromosomes. There are few terms which are used for describing the number of chromosomes found in egg. The term haploid means egg having single set of unpaired chromosomes.

The term diploid means having two sets of complete chromosomes obtaining from parents’ cell. The term triploid means having an extra set of unpaired chromosomes. The case of triploid is very rare and uncommon. It happens at very rare case. It is also not stable as diploid.

Final answer:

The three terms that can be used to describe the number of chromosomes in an egg, which is one set of chromosomes, are 'haploid', '1n' and '23 chromosomes'.

Explanation:

The terms that describe the number of chromosomes found in an egg are:

Haploid: This term represents cells that have a single set of chromosomes. In the context of your question, an egg is haploid because it contains one set of chromosomes. 1n: This term is often used to describe cells that contain one set of chromosomes, like eggs. The 'n' stands for one set of chromosomes. 23 chromosomes: This term represents the actual number of chromosomes found in an egg. Human eggs (and also sperm) carry 23 chromosomes out of the full 46, which is why they are called haploid.

A) water has a high heat of vaporization.
B) water has hydrogen bonds that promote cohesion.
C) the adhesive properties of water promote its capillarity.
D) the polarity of water molecules make it the universal solvent

Answers

Explanation:

D) the polarity of water molecules make it the universal solvent

In osmosis, molecules of water move across a semi permeable membrane, from regions of high concentration to regions of low concentration until an equilibrium is reached. This always occurs along the concentration gradient within the system.

Given that water is a universal solvent, capable of dissolving most chemical substances, solutes diffuse into water-filled regions constantly, and the osmotic potential, along with the solute potential may constantly undergo change. Osmosis, restores osmotic balance through the movement of water molecules while restricting the movement of solutes.

explain how sugar molecules combine with other elements to create amino acids. Why is this an essential process for living things?

Answers

Combination of sugar molecules with other elements

Explanation:

A molecule of sugar is basically constructed of carbon, oxygen, and hydrogen atoms linked together as hydrocarbons. This hydrocarbon with C-C bonding facilitates sugar molecules to combine with other atoms and form larger molecules like amino acids, nucleotides etc.

Carbon provides four free valence electrons to share and form covalent bonds with other elements like oxygen, nitrogen, hydrogen etc. Carbon also can link and form long chains of such C-C covalent bond and forms carbon-containing organic compounds.

The carbon, oxygen, hydrogen in sugar molecules combine with nitrogen to form alkaloids and then with sulfur to form amino acids.

Amino acids are the building blocks of proteins which perform various functions as hormones, antibodies, pigments, structural proteins etc and are highly necessary for a living thing to grow and survive.

If two tabby cats are crossed with each other, what is the likelihood that they’ll have a tabby kitten? a black kitten?

Answers

Final answer:

The likelihood of two tabby cats having tabby or black kittens depends on their genetics. If both parents have the relevant genes, the probability is higher, but variations can still occur.

Explanation:

The likelihood of two tabby cats having a tabby kitten depends on the genetics of the cats involved. In general, if both parents have the tabby gene, the probability of having a tabby kitten is high. However, if one or both parents do not have the tabby gene, the probability might be lower. It's important to note that coat color in cats is determined by multiple genes, so there can be variations in the coat color of the offspring even if both parents are tabbies.

The likelihood of two tabby cats having a black kitten is also influenced by genetics. If both parents have the black gene, there is a higher probability of having a black kitten. However, if one or both parents do not have the black gene, the likelihood of having a black kitten is lower. Again, it's important to consider that coat color in cats is determined by multiple genes, so there can be variations in the coat color of the offspring.

The correct answer is The likelihood of having a tabby kitten when two tabby cats are crossed is 100%. The likelihood of having a black kitten is 0%.

The tabby pattern is a coat colouring in cats characterized by stripes, dots, or swirling patterns. The tabby pattern is determined by the agouti gene, which controls the distribution of pigment in the hair shaft. There are different types of tabby patterns, including mackerel, classic, spotted, and ticked tabby.

When two tabby cats are crossed, they will produce kittens that exhibit the tabby pattern because the tabby pattern is a dominant trait. This means that even if the cats carry recessive genes for other coat colors or patterns, the dominant tabby gene will mask these recessive traits in the offspring. Therefore, all kittens from this cross will show some form of tabby pattern, making the likelihood of having a tabby kitten 100%.

The colour black in cats is determined by the presence of the black gene, which is separate from the agouti gene responsible for the tabby pattern. For a black kitten to be born, both parents must carry the recessive black gene. Since the question specifies that both parents are tabby, and there is no mention of them carrying the recessive black gene, we cannot assume that they do. Therefore, without the presence of the recessive black gene in both parents, the likelihood of having a black kitten from two tabby parents is 0%.

It is important to note that if the tabby parents are actually black tabbies (which is a colour variation where the tabby pattern is present but obscured by the black pigment), they could potentially have black kittens if they carry the recessive black gene. However, the question does not provide this information, so we assume that the parents are typical tabbies without the recessive black gene, and thus the likelihood of a black kitten is 0%.

With sympatric speciation a physical barrier arises and separates two populations ending gene flow between them.

Answers

Explanation;

False.

This describes allopatric speciation.

During the process of cell division, spontaneous changes within the genome can arise, called mutations. These are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes.

These mutations form variants which become stable within a population, leading to the formation of separate, genetically distinct populations called species. New species arise through several evolutionary mechanisms such as:

allopatric speciation- physical barriers to gene flow ; isolation of groups which evolve separately in their environments by accruing suitable traits, to become a new speciesperipatric speciation- similar to allopatric speciation, but one group is much smaller, making the unique traits more notable, or distinctparapatric speciation- subpopulations in a large geographic region evolve reproductive isolation by mating with those nearby, however they continue to undergo gene exchange along a common border regionand sympatric speciation- absence of physical barriers which hinder gene flow; reproductive isolation arise through many forms of the same genes called polymorphisms

D) The cell wall is the powerhouse of the cell, and controls the functions of the organelles.

Answers

C) Cell walls give plant cells a uniform structure, and allow the cell to grow taller.

The best way to explain why plant cells have a cell wall but animal cells do not is Cell walls give plant cells a uniform structure and allow them to grow taller.

Why don't animal cells have cell walls?Animal cells lack cell walls because they do not require them. Plant cells' cell walls maintain cell shape, almost as if each cell has its own exoskeleton. Plants can stand upright without the use of bones because of their rigidity.Plants benefit from standing upright and growing as tall as possible. Because plants require sunlight, growing taller than neighboring plants increases the likelihood that the plant will survive and reproduce successfully. Height can be an advantage for animals as well, but most animals have skeletons and musculature. To stand upright, they do not require the rigid network provided by cell walls.

D. From the energy stored in the mitochondria

Answers

Answer:

The correct answer is c from the motion of hydrogen ions.

Explanation:

Photosynthesis consist of 2 reactions among them one is light reaction and the other is dark reaction.

 Light reaction deals with the formation of ATP and NADPH,The ATP is formed by the flow of electrons through various electron carriers which is simultaneous to the transport of protons along their concentration gradient resulting in the formation of proton motive force(PMF).

  The generated PMF leads to form ATP.

Where do the end products of the light reactions travel too?

Answers

Answer:

There are two end products of the light reaction of photosynthesis, ATP and NADPH. These molecules are produced during the cyclic and the non-cyclic photophosphorylation reactions. These are the products which are used in the dark reactions.

The ATP and NADPH produced in the light reactions of photosynthesis are transported to the stroma of the chloroplast, where they are used in the Calvin cycle.

The end products of the light reactions of photosynthesis, which are ATP and NADPH, travel to the stroma of the chloroplast. Here, they are utilized in the Calvin cycle to synthesize organic molecules like glucose from carbon dioxide. The light reactions occur within the thylakoid membranes, where photon energy is harnessed to split water molecules, producing electrons, protons, and oxygen. The electrons move through an electron transport chain, resulting in the generation of ATP and NADPH. During this process, hydrogen ions (H+) are pumped into the thylakoid lumen, creating a proton gradient that powers ATP synthase for ATP production.

How much genetic diversity exists among siblings?

Genetic variation can be described as the variation in the genotype of organisms. Genetic variations are usually caused due to the meiosis. During meiosis, crossing over and homologous recombination occurs which allows genetic variations to occur. Due to this, about 50% of the DNA is different among siblings. 50% of the DNA is different in the parents and the offsprings. Hence, we can say that siblings are 50% genetically identical.

1. What is the end product of replication?

Answers

Answer:

In replication, the end result is two daughter cells.

Explanation:

The end product of DNA replication is two identical daughter DNA molecules, each composed of one old and one new strand. The 'end-replication problem' causes a loss of DNA at the 5' end in linear chromosomes, which is partly addressed by telomeres.

The end product of replication is two identical daughter duplex DNA molecules. Each is comprised of one original (parental) and one new (daughter) DNA strand. This occurs due to DNA replication, which is essential for cell division and is facilitated by a host of enzymes and proteins. During this process, an RNA primer is required to initiate synthesis. Problems such as the end-replication problem affect the 5' ends of linear chromosomes, where RNA primers are removed, causing a gradual loss of DNA sequences with each cell division. Telomeres help mitigate this issue to an extent. The RNA primers used during replication are replaced with DNA nucleotides, but the primer at the 5' termini cannot be replaced, leading to progressively shorter DNA strands with successive replications.

Furthermore, in some organisms like bacteriophages, during replication, DNA can be produced in a concatameric form which is later cleaved to package a single genome inside the phage capsid. This unique replication method is important within the context of viral DNA replication.

Unicellular organisms can perform all of life’s functions within a single cell. Multicellular organisms have many cells that each perform a special function. Cells develop into their mature forms through the process of cell differentiation. Cells differ because different combinations of genes are expressed. Organs are groups of tissues that perform a specific or related function. Organ systems are groups of organs that carry out similar functions.

1. Describe how nighttime carbon dioxide concentrations near the forest should compare with the midday

concentrations near the forest. Explain your answer using two biological processes.

Answers

Answer: carbondioxide concentration is high at  night, and low during the midday.

Explanation:

This can be explained with the PHOSYNTHESIS and RESPIRATION (cellular respiration).

Photosynthesis is the process of manufacturing of food substances by plants, bacteria and some other organisms. These organisms use energy in sunlight to combine carbondioxide and water, in the presence of the green pigments (chlorophyll in leaves) and enzymes to form GLUCOSE and OXYGEN. Glucose is the main end product (digested food in plants.)The oxygen is for other organisms including man, and plants to breathe in.  

                                                SUNLIGHT

         C02 + H2 0                       ---------------- >      C6 H 12 06   + Oxygen

                                               Chlorophyll      

Sunlight is needed to breakdown   oxygen and protons in water molecules. This is the source of oxygen molecules in photosynthesis that we human and other animas take in. The hydrogen is needed for glucose production.

Therefore during the midday, the concentrations of CO2 at midday near the forest   is always low because plants continuously use these for photosynthesis, by removing it from atmosphere.

However, at night time   C02 concentration near the forest is always high. This is because at night, the rate photosynthesis drops because there is no sunlight. But plant undergo respiration by breaking down the glucose manufactured during (phosynthesis) by combining it with oxygen to produce carbondioxide, and water vapour. This increases C02 concentrations at night.  

       Glucose + Oxygen    ------> Carbondioxide and Water

Excess glucose is stored as glycogen in the liver.

Explanation:

The statement that best describes glucose is that it is a monosaccharide with the chemical formula C6H12O6 and is the body's most readily available source of energy. Glucose is pivotal for the energy requirements in both plants and animals. In plants, glucose is synthesized using carbon dioxide and water during the process of photosynthesis, and excess glucose is stored as starch.

In the human body, glucose enters the cells via the circulatory system. Here, through a series of reactions known as glycolysis, glucose is broken down, which helps in the formation of adenosine triphosphate (ATP), an essential molecule that provides the energy required for several cellular functions.

A cell from a tissue culture has 38 chromosomes. After mitosis and cytokinesis, one daughter cell has 39 chromosomes and other has 37. What might have occurred to cause the abnormal chromosome numbers?​

Answers

The spindle fibres of a chromosome failed to separate a chromosome to sister chromatids during anaphase of mitosis resulting in an additional sister chromatid being pulled into a Daughter cell, hence having 39 chromosomes; and the other Daughter cell having one less chromosome.

An abnormal number of chromosomes is known as aneuploidy, which is a kind of chromosomal abnormality.

What are abnormal chromosome numbers?​

By either adding or losing chromosomes during mitosis, an aneuploidy results in daughter cells with a total number of chromosomes that is not an exact multiple of a haploid set.

Aneuploidies are typical of several chromosomal abnormalities and cancer cells. In addition, monosomy is a kind of aneuploidy in which daughter cells have just one copy of each chromosome rather than the two copies that diploid cells have.

For instance, the removal of the X chromosome results in Turner syndrome, a monosomy.

Therefore, one daughter cell having 39 chromosomes and the other having 37, is due to aneuploidy.
