The cells have a capsule which allows it to evade the immune system of the mice. So, Last option is accurate.

The characteristic of the S strain that allows it to evade the immune system of mice is that the cells have a capsule. The capsule is a protective layer that surrounds the bacterial cell and makes it difficult for the immune system to recognize and attack the bacteria. The capsule can also help the bacteria avoid being engulfed by phagocytes, which are immune cells that can engulf and destroy bacteria. This allows the S strain to evade the immune system and cause disease in the mice.

Genetic variety in a population is expected to decrease if non-sister chromatids fail to cross across during meiosis.

Genetic variety is produced over time by populations and can be specifically or stochastically suppressed by selection or genetic bottlenecks. Following a bottleneck, a small number of randomly chosen people form a founder population, which causes genetic drift.

Genetic variation can be increased by human mutations and alleles being created as a result of gene duplication, recombination, or other events. A population can generate new genetic variation within a few generations, hence a population with high rates of reproduction would likely have a high level of genetic diversity.

It is not true that thrombocytopenia increases the risk of embolus formation. Option A is correct.

Thrombocytopenia is a medical condition characterized by a low platelet count in the blood, which can increase the risk of bleeding and bruising. Platelets are important for blood clotting, so a decrease in their number or function can lead to bleeding disorders.

However, a low platelet count does not directly increase the risk of embolus formation, which is a blood clot that travels to another part of the body and can cause blockage of blood vessels.

The other options are true of thrombocytopenia: it may produce petechiae (small red or purple spots on the skin caused by bleeding under the skin), it is caused by having a low number of circulating platelets, and it can be caused by conditions that destroy bone marrow (where platelets are produced), such as chemotherapy, radiation therapy, and certain infections.

When the heterozygous genotype results in a phenotype where both alleles are fully and separately expressed, it is called codominance. In this case, neither allele is dominant or recessive, and both are fully expressed in the phenotype of the organism.

For example, in the case of human blood types, the A and B alleles are codominant, meaning that if an individual inherits one A allele and one B allele (heterozygous genotype), both antigens will be fully expressed on the surface of their red blood cells. As a result, the individual will have a blood type AB, which is different from the A and B blood types that result from the homozygous expression of one of the alleles. Codominance results in a unique phenotype that reflects the full expression of both alleles and provides an additional level of genetic variation within a population.

Capsules are neutrally charged. In this staining procedure, the purpose of emulsifying the sample in serum is to facilitate the staining of capsules.

Emulsifying a bacterial specimen in serum allows capsules to be stained because capsules are made of water-soluble complex polysaccharides that cannot be stained by the traditional Gram stain technique because they are resistant to dyes. A capsule is a slimy, non-rigid structure that serves as a means of evading the host's immune system.

Bacteria have the ability to create a protective capsule that is made up of complex polysaccharides, which shields the bacterial cell from being recognized and engulfed by white blood cells. Capsules assist bacteria in remaining attached to surfaces, including host tissues and implanted medical devices, and allow for bacterial growth in biofilms, which are aggregates of microorganisms that grow on surfaces immersed in fluids.

In order to eliminate red plants if you start with two pink plants, you will need to perform a process called backcrossing.

Backcrossing involves crossing a hybrid organism (in this case, pink plants) with one of the parent organisms (in this case, red plants). This will result in offspring that are the same as the parent organism (in this case, red plants). After the backcross, the red plants can then be isolated from the other plants and removed from the population.

To carry out backcrossing, you must first identify the parent organism. This is usually done through phenotype, or the physical characteristics of the plant. In this case, if you have two pink plants, you must identify which parent organism is the red plant and which parent organism is the white plant. Once you have identified the parent organism, you will then cross the pink plant with the red plant.

This will result in the production of offspring that are identical to the red parent organism. The red plants can then be removed from the population, leaving the white plants and any other offspring that may have been produced in the backcross.

Backcrossing is a useful technique for eliminating a particular genotype from a population, as it allows you to control the genotypes of the offspring produced. In this case, it allows you to isolate and remove the red plants from the population.

The correct answer is B. Future earthquakes are likely because underground stress builds up in similar locations.

The occurrence of earthquakes is primarily determined by tectonic plate movement and stress accumulation in the Earth's crust. If a region has experienced earthquakes in the past, it suggests that the area is located in a region where tectonic plates meet or where there are active faults. As stress accumulates due to the movement of tectonic plates, the rocks in the region become strained and can eventually rupture, causing an earthquake.

Therefore, the occurrence of past earthquakes indicates that there is a potential for future earthquakes in the same location as the underground stress builds up in similar areas.

If the addition of an inhibitor does not change the maximal reaction rate of an enzyme and substrate combination, then the inhibitor is a competitive inhibitor.

A competitive inhibitor is a type of enzyme inhibitor that binds to the active site of an enzyme, preventing the binding of the substrate. Since the inhibitor competes with the substrate for binding to the active site, the reaction rate can be restored by increasing the concentration of the substrate.

In the presence of a competitive inhibitor, the maximal reaction rate of the enzyme and substrate combination remains the same, but the apparent affinity of the enzyme for the substrate is reduced. This means that a higher concentration of substrate is required to achieve the same reaction rate in the presence of the inhibitor.

Therefore, if the maximal reaction rate of an enzyme and substrate combination is unaffected by the addition of an inhibitor, the inhibitor is a competitive inhibitor.

A volcanic eruption that covers a region with lava and destroys the biodiversity of the ecosystem can have the following two consequences:

A. A very long period of time will pass before a new ecosystem can be established: The volcanic eruption can completely destroy the existing ecosystem, leaving a barren landscape. The lava may take a very long time to cool and solidify, and the process of weathering and soil formation that is necessary for new plants to grow can be slow. Therefore, it may take many years or even centuries for a new ecosystem to establish itself.

D. The ecosystem must now undergo primary succession: Primary succession is the process of colonization and establishment of plants and animals in an area that was previously barren, such as the area covered by lava in the case of a volcanic eruption. Since the existing ecosystem has been completely destroyed, the area will need to undergo primary succession for new plants and animals to establish themselves.
