Interphase which consist of G1 phase S phase and G2 phase

Interphase is followed by mitosis/meiosis

MITOSIS consist of four main phases Prophase, Metaphase, Anaphase, and Telophase.

Cytokenisis would then follow MITOSIS resulting in divission down the cleavage furrow formed between Anaphase and Telophase.

Answer:

The euakaryotic cell is considered to be more adanced form of life on the planet, as the scientists believes that many unicellular cells(which are termed as the organelles inside the cell) made a specialized form of network with one another. And this network of cells was then attributed the name of a eukaryotic  cell, as many number of eukaryotic cells combined together to form a specialized system or form of a cellular body. But, the eukaryotic cells increased its number and was the entity with the most diverse functions and shapes. But, however the eukaryotic cell had a different way to replicate itself and for that reason the process of mitosis and meiosis takes place inside the system created by the eukaryotic cells.

Mitosis: During, the process of mitosis the different cells undergo the replication process in such a way that each cells are tend to be divided into the equal number of halves, as these new born cells contain the same number of chromosomes(genetic material) same as the parent cells have. While, the resemble the parent cells in there genotypes.

Meiosis: While, the meiosis is more concerned with the half number of chromosomes inside each daughter cells that are produced after the parents cells are gone through the process of meiosis. Having the half number of chromosomes does not mean that it would posses some sort of abnormalities but the genetic materials gets there level of stability after some time, and more over going through a process of growth and development.

Enzymes are catalysts, which means they are not consumed by the chemical reactions they catalyze.

The correct answer is D. All enzymes are proteins.

D. All enzymes are proteins is the correct answer as it is NOT TRUE concerning enzymes. While the majority of enzymes are proteins, there are a few exceptions. Ribozymes, for example, are enzymes that are composed of RNA molecules rather than proteins.

Enzymes have optimal environmental conditions, which refers to specific pH and temperature ranges where the enzyme operates most efficiently. They are not consumed by the reactions they catalyze, meaning that they can be reused. Enzymes can catalyze only one or a very few different reactions, and they can catalyze both spontaneous and non-spontaneous reactions.

Gaseous cycle

Explanation:

Gaseous cycle inclines to travel more frequently than the sedimentary ones. To adjust more steadily to  the changes in the biosphere because of the large atmosphere reservoir. The buildup of carbon dioxide are soon dissipated by wind or taken up by the plants. The extraordinary disturbances i.e. global warming are more often than local disturbances which is wild fires and storm driven events. During the rock phase other salt deposits out as  rock  and sediment in shallow seas eventually to be weathered and can be recycled.

The question pertains to a stage in biogeochemical cycles where nutrients move rapidly; these cycles help maintain ecosystem health by keeping essential elements available.

The part of a biogeochemical cycle being described relates to a phase where nutrients are in a state of rapid movement and transition, typically referred to as the 'active' or 'main' cycle. In this stage, elements move swiftly through the ecosystem, being taken up by organisms, traveling through food webs, and also cycling through the physical environment, such as soil and water.

This rapid cycling ensures that essential elements remain available to support life. An example is the circulation of nitrogen, which can be rapidly integrated into biological systems through the process of nitrogen fixation and become part of the proteins and nucleic acids in living organisms.

Answer:

  Variations Within Ecosystems

Ecosystem diversity can be described as a term which is used o describe the changes within an ecosystem and the impact these changes have on the environment and humans.

Variations within an ecosystem can cause genetic drifts. Variations will cause those organisms to survive which are better adapted to survive to the changes which occur in an ecosystem. And the organisms which are not better suited become extinct over a period of time. Hence, this will lead to a wide rise in biodiversity.

Answer:

D

Explanation:

This is coming straight from USAtestprep, The paramecium will gain water in the hypotonic environment and will be unable to regulate its water levels, resulting in lysis.

The paramecium will gain water in the hypotonic environment and will be unable to regulate its water levels, resulting in lysis. Thus, option D is correct.

A paramecium is a single-celled, freshwater protist that lacks a cell wall but contains a contractile vacuole. The contractile vacuole is surrounded by rings of proteins that can contract when the vacuole is filled with water, expelling the water from the paramecium.

When the paramecium placed into a freshwater aquarium that has been treated with a chemical that disrupts the function of the contractile vacuole than the paramecium will gain water in the hypotonic environment and will be unable to regulate its water levels, resulting in lysis.

The paramecium will balance its water levels with exocytosis of water droplets through its membrane.The paramecium will expel sodium ions from its cytoplasm to allow less water to enter through its membrane.The paramecium will lose water to the environment without the ability to regulate its water levels, resulting in cell death.

Therefore, The paramecium will gain water in the hypotonic environment and will be unable to regulate its water levels, resulting in lysis. Thus, option D is correct.

Nucleic acids are polymers made up of nucleotides. They store genetic information in a coded form.

Answer:

2 reactants and 2 products. All are compounds

Explanation:

Answer : The correct option is, two reactants and two products.

Explanation :

Double replacement reaction : It is a type of chemical reaction in which a positive cation and a negative anion of two reactants exchange their places to form two new products.

It is represented as,

[tex]XY+AB\rightarrow XB+AY[/tex]

(X and A are the cations, Y and B are the anions)

For example : Barium chloride react with magnesium sulfate to give barium sulfate and magnesium chloride as a product.

The balanced chemical reaction will be:

[tex]BaCl_2+MgSO_4\rightarrow MgCl_2+BaSO_4[/tex]

From this we conclude that, there are two reactants and two products are present in a double-replacement reaction.

Hence, the correct option is, two reactants and two products.

Explanation:

Watershed are connected to water basins, rivers and ponds and therefore if its protected from being polluted through recycling runoff, it reduces polluting the waters and therefore agricultural pollution is reduces.

Answer:

The correct option is B. All ecosystems contain symbiotic relationships.

Explanation:

Symbiotic relationship can be described as a relationship between the organisms of two species. It might be harmful for both the species, beneficial for both the species or just beneficial to one of the species. All ecosystems will have some kind of symbiotic relationships. Hence, option B is correct.

Other options like Option A is false because the desert ecosystem does has symbiotic relationships. For example, the Gobi woodpecker lives on a cactus in a desert. In return it eats the insects and other parasites which harm the cactus.

The correct answer is A. deserts.

Symbiotic relationships are interactions between two or more organisms from different species that live in close physical association with each other. These relationships can be beneficial to one or both organisms (mutualism), beneficial to one while having no effect on the other (commensalism), or beneficial to one while being harmful to the other (parasitism).

In ecosystems, symbiotic relationships are widespread and can be found in virtually all environments where life exists. This includes deserts, tropical rainforests, coral reefs, tundras, and even human bodies, where millions of bacteria form symbiotic relationships with their host.

Option B states that all ecosystems contain symbiotic relationships, which is generally true. However, the question asks for an option that does NOT have symbiotic relationships, which means we are looking for an exception to this general rule.

Deserts (option A) are often characterized by harsh conditions, including extreme temperatures, low precipitation, and limited resources. While it is true that deserts can have fewer visible examples of symbiotic relationships due to the sparse distribution of organisms, symbiotic relationships do still exist in desert ecosystems. For example, cacti may have mutualistic relationships with certain species of birds or insects that nest in them or help with pollination.

Tropical rainforests (option C) are known for their high biodiversity and complex web of interactions, including a multitude of symbiotic relationships.

Therefore, the most accurate answer to the question is that all ecosystems, including deserts, contain symbiotic relationships to some extent. However, if we were to identify an ecosystem with fewer symbiotic relationships compared to others, deserts might be considered due to their extreme conditions and lower organism density. It's important to note that the question's premise is somewhat flawed because symbiotic relationships, even if less visible or less diverse, are present in all ecosystems.

A nuclear envelope forms around each set of chromosomes, and a nucleolus forms in each of the newly forming cells. Copied DNA coils into chromosomes. ... Kinetochore fibers move chromosomes to the cell's center.

Answer:

it will form a Telophase

Explanation:

During telophase, the newly separated chromosomes reach the mitotic spindle and a nuclear membrane forms around each set of chromosomes, thus creating two separate nuclei inside the same cell. As Figure 4 illustrates, the cytoplasm then divides to produce two identical cells.

The rough endoplasmic reticulum, with its surface-bound ribosomes, is the site for synthesis of enzymes intended for export in eukaryotic cells. Post-synthesis, these proteins are modified in the Golgi apparatus before being transported to their final destinations.

The cellular structure most likely involved in the synthesis of enzymes for export is the endoplasmic reticulum (ER), specifically the rough ER due to the presence of ribosomes on its surface. Enzymes, which are proteins necessary for catalyzing various biological processes, are synthesized by ribosomes that are found either floating freely in the cytoplasm or attached to the rough ER. When enzymes are meant for export or for use in lysosomes, the rough ER becomes the primary site of synthesis. After synthesis, these proteins are usually sent to the Golgi apparatus for further modification and sorting, before being shipped to their final destinations.

Cells that are highly active in protein synthesis, such as those in the pancreas that produce digestive enzymes, have a large number of ribosomes. Moreover, certain enzymes are compartmentalized within specific organelles, like mitochondria, which house enzymes involved in cellular respiration; or lysosomes, which contain enzymes that break down cellular debris. This compartmentalization provides efficient and regulated chemical reactions within the cell.

Answer:

Explanation:

Characterized by their flat, open pastures and abundance of nutrient-rich soil, more than a quarter of the world’s land—and about 70 percent of its agricultural land—is covered by grasslands.

This biome is home to a range of flora and fauna, which add to its resilience against natural disasters such as droughts or wildfires. In fact, native grassland plants have adapted to extreme weather conditions to such an extent that savannas, a subset of grasslands found in Africa, Australia, South America, and India, require seasonal droughts and wildfires to maintain biodiversity

But this resiliency does not equate to immunity.

Grasslands are threatened by habitat loss, which can be caused by human actions, such as unsustainable agricultural practices, overgrazing, and crop clearing. Almost half of all temperate grasslands and 16 percent of tropical grasslands have been converted to agricultural or industrial uses and only one percent of the original tallgrass prairie exists today.

Answer:

The phenotype of the sneaky neighbor dog will be pink. Let's consider the phenotype of our spotted gummed Labrador to be CPCB and neighbors dog to be CPCP

          CP          CB

CP     CPCP       CPCB

CP     CPCP      CPCB

The results of this cross show that there will be a probability of having pink dogs as well as spotted dogs. Hence, this proves that the neighbors dog had pink gums.

Final answer:

The genotype of the sneaky neighbor dog is likely pp, resulting in a pink gum phenotype, because when this dog mated with a Bp (black and pink spotted gums) Labrador, half of the puppies had pink gums.

Explanation:

The observation that half of the Labrador retriever puppies have spotted gums while the other half have pink gums suggests that gum coloration in dogs displays a pattern of co-dominance. In this case, the phenotype of the puppies informs us about the possible genotype of the parents.

Since the Labrador mother has spotted gums, her genotype for gum color must be one allele for black and one for pink, expressed as Bp. The appearance of some puppies with pink gums indicates they must be pp, receiving a pink allele from both parents. Thus, the father (the sneaky neighbor dog) must have a pp genotype to produce pups with pink gums when mated with a Bp Labrador.

To conclude, the phenotype of the sneaky neighbor dog is likely to be pink gums.

Fleas on a dog represent parasitism because the fleas benefit by obtaining nutrients at the dog's expense, potentially causing illness to the dog. The example of parasitism among the options provided is B.

Parasitism is a type of symbiotic relationship where one organism, the parasite, benefits at the expense of another organism, the host. The flea acts as a parasite by living on the dog and deriving nutrients from it, while the dog suffers harm, often in the form of illness or discomfort. This detrimental effect on the host is a hallmark of parasitism.

The immune system protects the body from possibly harmful substances by recognizing and responding to antigens. Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. Nonliving substances such as toxins, chemicals, drugs, and foreign particles (such as a splinter) can also be antigens. The immune system recognizes and destroys, or tries to destroy, substances that contain antigens.  Your body's cells have proteins that are antigens. These include a group of antigens called HLA antigens. Your immune system learns to see these antigens as normal and usually does not react against them.

Innate, or nonspecific, immunity is the defense system with which you were born. It protects you against all antigens. Innate immunity involves barriers that keep harmful materials from entering your body. These barriers form the first line of defense in the immune response. Examples of innate immunity include:

Cough reflex

Enzymes in tears and skin oils

Mucus, which traps bacteria and small particles

Skin

Stomach acid

Innate immunity also comes in a protein chemical form, called innate humoral immunity. Examples include the body's complement system and substances called interferon and interleukin-1 (which causes fever).  If an antigen gets past these barriers, it is attacked and destroyed by other parts of the immune system.  Acquired immunity is immunity that develops with exposure to various antigens. Your immune system builds a defense against that specific antigen.  Passive immunity is due to antibodies that are produced in a body other than your own. Infants have passive immunity because they are born with antibodies that are transferred through the placenta from their mother. These antibodies disappear between ages 6 and 12 months.  Passive immunization may also be due to injection of antiserum, which contains antibodies that are formed by another person or animal. It provides immediate protection against an antigen, but does not provide long-lasting protection. Immune serum globulin (given for hepatitis exposure) and tetanus antitoxin are examples of passive immunization.

Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. ... Your immune system learns to see these antigens as normal and usually does not react against them. INNATE IMMUNITY. Innate, or nonspecific, immunity is the defense system with which you were born

Answer:

Specific Defense

Explanation:

Specific immune system gets activated when the pathogens (foreign elements) enter the body and are able enough to bypass the innate immune defenses thereby activating the adaptive immune system  

Specific defense is triggered by elements found on the surface of pathogens. These surface elements are called antigens. Antigens responds to these pathogens by producing antibodies specific to pathogen surface type.

Answer:

'The rule of 10' is associated with the pyramids of quantifying energy flow.

Only a small amount of energy is transferred from one trophic level to another. Most of the energy is lost in the form of heat. Hence, we quantify that about 10% of energy travels from one trophic level to another.

Let's say the producers have 100% energy. The primary consumers will only receive 10% of this energy. The secondary consumers will receive 1% energy from the primary consumers. The tertiary consumers will receive 0.1% energy. This is known as the rule of 10.

Answer:

During evolution, plants have acquired a vascular system, which has greatly contributed to the success of land plants. The vascular system allows plants to rapidly transport water and nutrients over long distances between roots, growing deeply in soil, and shoots, growing upward toward the sun.

Answer:

It made it possible to move water within the plant structure.

Explanation:

The evolution of plants occurred, mainly, after atmospheric changes due to the release of oxygen by autotrophic organisms. Thus, the first species to colonize the terrestrial environment were bryophytes and mosses, and the main characteristic that facilitated colonization after the formation of multicellular organisms was the formation of epidermal tissue and structures that guaranteed protection against water loss, the movement of water within the plant.

In the Paleozoic period, the first plants with vascular systems emerged, which developed from the first plant groups that colonized the terrestrial environment. The vascular system is composed of xylem and phloem which are the vessels that conduct nutrients and water within the plant.

About 400 million years ago, ancestral plants went through several events of adaptive irradiation, and diversified into the different species that we know today. These adaptive events were fundamental for the colonization of the terrestrial environment, so that diverse environments with adverse conditions were colonized by the plants.

After the appearance of sap-carrying vessels, plants evolved and tall species emerged that constituted the first forests, even at the end of the Devonian period.

Most of the plants survived the extinction events of the Triassic period, however, the environmental and atmospheric changes may have caused more evolutionary events, mainly in relation to the formation of flowers and fruits, which exponentially increased the biodiversity of terrestrial flora from the period Cretaceous.

In addition to the morphological and physiological changes over evolutionary events, another important process in the evolution of plants is reproduction and, indirectly, dependence on water for this process.
