Explanation:
Succession occurs because a. organisms gradually change the environment
Succession involves small scale changes within a community that occur repeatedly over the life of that community.
Ecological communities are highly dynamic- they gradually evolve. Typically their progression involves:
colonizing species exploiting uninhabited areas (Primary succession) becoming a habitable and increasingly complex community there is increased diversity of organisms (Secondary)Further Explanation:
The makeup of biological communities is crucial to defining Primary and Secondary succession; eventually, through changes in this makeup, a steady-state or equilibrium is reached called a climax community. While Primary succession starts off with the modification of a previously unoccupied area along with increasing variation; secondary succession begins after major disruption in the community such as fires, storms and flooding.
However, the process of becoming a climax community can be pretty complicated- it is very dependent on other factors like temperature and rainfall. Communities that experience rapid change, frequent major disruptions and even human intervention, are less likely to attain a stable equilibrium and may never become climax communities.

Explain the properties of water and why it is important to life. Include the following: specific heat, density, polarity, Universal solvent
Final answer:
Water is crucial to life due to its unique properties such as high specific heat, low density as ice, polarity, and role as a universal solvent. These properties enable temperature regulation, solvent capabilities, metabolic reactions, and maintenance of homeostasis within living organisms.
Explanation:
Water is essential to life largely due to its unique properties. Its polarity and ability to form hydrogen bonds make it an ideal medium for biological processes. These bonds are responsible for water's high specific heat, which allows it to absorb heat without a significant change in temperature, protecting living organisms from drastic temperature swings. The density of water plays a crucial role in aquatic ecosystems, as ice, being less dense than liquid water, floats and provides insulation.
As a universal solvent, water can dissolve a wide range of substances, which is vital for cellular metabolism and transporting nutrients and waste materials. The cohesive and adhesive properties of water contribute to the movement of water against gravity in plants and the formation of droplets. Lastly, water's role in homeostasis is seen in its ability to buffer changes in pH, which is essential for the function of enzymes and other biochemical reactions.
Understanding the special properties of water is fundamental in comprehending how it supports life on Earth, from cellular functions to global climate patterns.

How many chromatids are there in one duplicated chromosome
Answer:
There are two chromatids in one duplicated chromosome.
Explanation:
Before any cell undergoes the process of cell division, the chromosomes of the cell duplicate themselves. This results in the formation of two chromatids which are known as the sister chromatids. The chromatids are joined together from the centre at a position called the centromere. The chromatids contain the same kind of DNA in them. Chromatids are often confused with homologous chromosomes. They are not homologous chromosomes, they are the copy of a chromosome.
In biology, a duplicated chromosome contains two identical copies (chromatids) that are attached via a structure known as the centromere.
Explanation:In biology, a duplicated chromosome has two identical copies (chromatids) attached to each other by a structure called the centromere. Hence, we can say that in one duplicated chromosome, there are two chromatids. This state typically exists after DNA replication, a process during the S phase of the cell cycle, and before cell division, when chromatids separate into each new cell.

how many amino acids does each codon code for?
Explanation:
Each codon codes for only one amino acid.
However, for one amino acid, multiple codons maybe encoded. While there are 64 codons, and four nucleotides in groups of three, only 20 amino acids may be encoded by these triplets, showing that the code is degenerate.
RNA codons determine certain amino acids, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Guanine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.
Further Explanation:
The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes; RNA codons determine certain amino acids, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Guanine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.
Nucleic acids like DNA stores all of an organism’s genetic information. Nucleic acid molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. Conversely, RNA nucleotides are Adenine, Guanine, Cysteine and Uracil. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule.
In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis. Thus, these contribute to the broad diversity of living organisms, as varied combinations of these 64 codons can produce many proteins which can be organized into cells, tissues and organisms.

Each codon, made up of three nucleotides, codes for one amino acid. But due to the degeneracy of the genetic code, most amino acids are specified by multiple codons, with a total of 64 possible codons and only 20 common amino acids.
Explanation:Each codon is composed of three nucleotides and codes for a single amino acid. However, the genetic code is degenerate, meaning that most amino acids are encoded by more than one codon. There are 64 possible codons, but only 20 common amino acids. Among these codons, 61 code for amino acids and the remaining 3 are stop codons that signal the end of protein synthesis. The degeneracy primarily occurs in the third nucleotide of the codon, which is often referred to as the wobble position. Notably, the amino acids methionine (AUG) and tryptophan (UGG) are the only two encoded by a single codon each. This characteristic of the genetic code helps to protect against mutations that might otherwise be harmful if the code were not redundant.

19. Interphase
20. Interphase
21. Prophase
22. Interphase
Explanation:
The cell cycle is divided into two main divisions. The Interphase ad the M phase or the Mitotic phase.
Throughout Interphase, the cell is not dividing yet, but it is preparing to divide. It synthesizes the nutrients it will need, and grows in preparation to become two cells. This is actually the phase the cell spends the longest time.
Mitotic phase is when the cell starts to divide. It is separated into:
Prophase:
In this phase the chromosomes are condensed and mitotic spindles start to form. These spindles are made up of microtubules that will help later on to split the chromosomes. The nuclear membrane disappears so that the chromosomes will be free to move.
Metaphase
This phase is marked by the alignment of the chromosomes in the middle of the cell. They line up and you will find the asters at the opposite ends of the cell, where the microtubules stem from, attaching themselves to the center of the chromosomes, which we call the kinetochore.
Anaphase
In this phase you will see that the chromosomes are separated by the spindle fibers and are pulled at opposite ends of the cell. The cell then becomes longer by the other spindle fibers that are not attached to a chromosome.
Telophase
This phase is the end phase. The two sets of chromosomes are then enclosed by new nuclear membranes forming two nuclei and other cellular structures just as the cells are about to separate completely. As the two new cells move further apart, in plant cells a cell plate forms, dividing the two cells. The movement of the two cells splitting apart is called cytokinesis and it happens just as mitosis is about to end.
Attached is a picture of the cell cycle of a plant cell.
In the plant cell cycle, the numbered stages typically include Interphase, Prophase, Metaphase, Anaphase, and Telophase. Each stage carries out specific tasks for cell division and growth.
Explanation:The sequence of the numbered stages in the plant cell cycle typically follows this order:
Interphase: This is the period of growth and preparation for division. During Interphase, the cell doubles its DNA and synthesizes new proteins and organelles. Prophase: The chromosomes condense and become visible, while the nuclear envelope disappears. Metaphase: The chromosomes align at the middle of the cell (the metaphase plate). Anaphase: The sister chromatids are separated and moved to opposite ends of the cell. Telophase: A nuclear envelope re-forms around each set of chromosomes, and the chromosomes uncoil and become less visible. Cytokinesis occurs concurrently, splitting the cell into two.FINA could possibly refer to the final phase or stage, but without further context, it's difficult to ascertain its meaning in this situation.

Cell theory explains the main parts of a cell and how cells reproduce.
Cell theory states that non-living matter can make cells that becoming living things.
The answer is the 2nd sentence. This is because all living things come from other living things, due to reproduction, which is what the cell theory is based off of.
Cell theory states that all living things are made of cells that come from other living cells is statement that best describes cell theory.
The cell theory, applied to biology, is responsible for identifying and describing the properties of cells, holding that all living things can be made up of a single cell or several.
The cell is considered the basic unit of life, which through a process in which cells are split or divided, gives way to the existence of new cells.
This indicates that every cell originates from the division of another cell and therefore contains the necessary genetic information within themselves.
Therefore, we can conclude that the cell theory indicates the cell as a unit of origin, being the basic unit of life, the only unit from which others can be born and being necessarily from a pre-existing one.

In sickle cell anemia, the sixth amino acid in the beta chain is valine instead of glutamic acid due to a single nucleotide change. This substitution changes the protein's structure and function, causing red blood cells to assume a sickle shape.
Hemoglobin is a protein in the blood made up of four polypeptide chains: two alpha chains composed of 141 amino acids each and two beta chains composed of 146 amino acids each, totaling 574 amino acids. In sickle cell anemia, one incorrect amino acid in the beta chain causes a change in the structure and function of the protein. Specifically, in hemoglobin S, the sixth amino acid in the beta chain is valine instead of glutamic acid found in hemoglobin A.This difference is due to a single nucleotide change in the gene encoding the beta chain, which results in the substitution of valine for glutamic acid, altering the protein's structure and function, leading to the characteristic sickle shape of the red blood cells in individuals with sickle cell anemia.

3. Can you rule out any of the men as Lisa’s father based ONLY on his Rh type?
4. Which of the MEN could safely donate blood to Lisa?
Without knowing the exact blood types (ABO and Rh) of Lisa and the men, it's not possible to definitively rule any man out as being Lisa's father or potential blood donors. However, a man with Type O, Rh- blood could donate blood to virtually anyone, including Lisa.
Explanation:To answer all three questions regarding Lisa's potential father and the men that can donate blood to Lisa, we would require the ABO and Rh types of both Lisa and the potential fathers. The basic principle is that a person of a specific blood type can receive blood only from his own type or type O (universal donor), and a person with an Rh- blood cannot receive Rh+ blood but vice versa is possible.
Let's go through them one by one:
Without knowing Lisa and the man's ABO type, we can't conclusively rule anyone out based solely on this factor.The same principle applies to the Rh type. If Lisa is Rh-, only men who are also Rh- could potentially be her father.

Final answer:
DNA fingerprinting is the technology used to identify individuals for paternity testing, criminal investigations, and missing person identification by analyzing variations in DNA sequences.
Explanation:
The DNA technology used to identify a correct father, a suspect using a small sample of evidence, and a missing person is commonly known as DNA fingerprinting or genetic fingerprinting. This technology analyses the variability in DNA sequences to match individuals with biological samples. For paternity tests, technicians compare DNA sequences from the mother, child, and potential father. In forensic cases, geneticists compare the DNA from crime scene evidence to that of suspects to find a match.
DNA fingerprinting is incredibly powerful because it utilizes the parts of human DNA that show high variability, meaning those sequences that are likely to be different in each individual, except for identical twins. The process typically involves amplifying a specific region of DNA, often using a method called Polymerase Chain Reaction (PCR), and then separating and analyzing the DNA fragments by gel electrophoresis.
Furthermore, the use of restriction enzymes allows DNA molecules to be cleaved at specific points, making the analysis more precise. DNA collected from various sources such as hair, blood, or saliva, can uniquely identify individuals, establishing relationships or linking suspects to crime scenes based on their unique genetic makeup.

Answer:
Crossing over and independent assortment
Explanation:
Meiosis can be described as a type of cell division which occurs in the sex cells. All the other cells of the body divide by mitosis.
During the process of meiosis, crossing over and independent assortment of chromosomes takes place which is the reason for the genetic variety produced in offsprings.
During crossing over, exchange of DNA segment between homologous chromosomes occur due to which genetic variations occur.
Also, the chromosomes assort independently in gametes during the process of meiosis due to which genetic variability is produced.
can we culture virus like they do with bacteria media?
Answer:
Viruses cannot be cultured in media like, bacteria, but in a living cells.
Explanation:
In order to identify a virus the following techniques are performed: PCR (single round) or nested/semi-nested PCR, real-time PCR, direct electronic microscopy, antigen capture, isolation (gold standard for viruses that can be cultured). Viruses cannot be cultured in media like, bacteria, but in a living cells.
Virus culture is based upon amplification of potentially infectious pathogens. Implies intracellular replication of viruses in the cytoplasm or in the nucleus. It is controlled by regulations (i.e. bio-safety level 2, 3 or 4). It is possible to identificate and further investigate for pathogenicity, and antiviral sensitivity.
The primary cell culture is developed directly from living tissue and contain several different kinds of cells. They are expensive as they cannot be subcultured (passaged) more than a few times and hence new tissue needs to be obtained from animals on a regular basis. One example of a primary cell line is chicken embryo fibroblasts.
Diploid cell lines can be subcultured about 100 times before they die. Much more useful in the laboratory and they can be stored indefinitely in liquid nitrogen. An example of this type is human embryonic fibroblasts.
Continuous cell lines have lost the normal constraints on cell growth such as contact inhibition and mortality. They can be subcultured indefinitely in vitro. They are Hep-2, HeLa (from human cancers) and VERO (from Green African monkey kidney).
In order to obtain suitable specimens it is necessary to identify specimens with suitable information and to evaluate the success percent of the process. Transport attributes are 4⁰C,-20⁰C, dry ice (-79⁰C). According to the protocol, in vitro/in vivo cell cultures are used. There are blood specimens, stool, throat swabs, naso-pharyngeal aspirat, urine, saliva and biopsy of certain areas.
Virus detection may be non specific (cytopathogenic effect – microscope) or specific (immunological detection – antigen detection, PCR etc.).
Viral load estimation I performed by titration and/or plaque assay.
The most common culture limitations are the absence of detection system for the agent, inappropriate culture systems, viruses that cannot be cultured, a negative viral culture results does not mean that the agent is absent (PCR).

What molecule is physically produced to create specific phenotypes
Explanation:
- Proteins
The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, in the cell. Sequences of DNA make up genes which can have different forms called alleles and comprise the genotype. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins. These proteins, when expressed, are referred to as an organism's phenotype.
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.
Large chains of monomers form biological macromolecules which carry out many essential functions in the body these can include nucleic acids, carbohydrates, proteins and lipids. These are organic molecules, meaning they're ringed or long-chain Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N) and phosphorus (P).
Proteins are structural support molecules comprised of long chains of amino acids joined via peptide (CONH) bonds; these are 20 specific units that are arranged into several macromolecules. Amino acids are absorbed through digestion and are incorporated into the body’s cells to make up organs muscles signal molecules and an alternative energy source.

Part A - Name and describe the chemical process producers use to make glucose and the chemical process used by both consumers and producers to make ATP to contribute to the exchange.
Part B - Identify the products of each process and explain how these products are used in the exchange.
Answer:
The process that is used by producers to make glucose is called photosyntheis and the chemical process used by both producers ans consumers to make ATP ito contribute to the energy exchange is called cellular respiration.
Explanation:
Photosynthsis
Photosynthesis occue in the mesophyll tissue present in leaves of plants .During photosynthesis the green plants or producers acquires CO2 from the atmosphere and utilizes water in presence of sunlight to produce glucose molecules along with the liberation of oxygen gas.
Cellular respiration
During cellular respiration the glucose molecules are oxidized to form energy in form of ATP along with the production of water and carbon dioxide.
The O2 that formed during photosynthesis is inhaled by human beings for respiration whereas the CO2 that is produced as waste material inside our body is exhaled by us in the atmosphere.The CO2 is then used by the green plants to carry out photosynthesis.
Plants use photosynthesis to produce glucose and oxygen, and both plants and animals use cellular respiration to turn glucose into ATP, energy. The products of photosynthesis, glucose and oxygen, and the products of cellular respiration, ATP, carbon dioxide and water, contribute to the cycle of energy exchange in ecosystems.
Explanation:
Part A - The chemical process used by producers, such as plants, to make glucose is called photosynthesis. This process uses carbon dioxide, water, and sunlight to produce glucose and oxygen. On the other hand, both consumers (animals) and producers (plants) use a chemical process called cellular respiration to convert glucose into a form of energy known as ATP (adenosine triphosphate).
Part B - The products of photosynthesis are glucose and oxygen.
