Unlike natural selection, genetic drift does not depend on an allele’s beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation.

Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele’s adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100\%100%100, percent frequency) of a harmful allele in a population.

The founder effect and the bottleneck effect are cases in which a small population is formed from a larger population. These “sampled” populations often do not represent the genetic diversity of the original population, and their small size means they may experience strong drift for generations.

Most of the mutations have no effects whatsoever on the organisms but some can be dangerous. There are two types of mutations that cause harm to the organism's ability to survive:teratogen muations are the mutations that form inside the uterus when the fetus is still developing and can even kill it or cause severe malformations that lead to death in the early life. Carcinogen mutations are the ones that lead to the formation of neoplasms(masses of cells that divide uncontrollably, basicly cancer).

An oligomeric enzyme transitions from a T to R state as substrate binds, producing positive cooperativity. If a heterotropic all
V125BC [204]

Answer:

Increase

Explanation:

Oligomeric enzyme have more than one polypeptide chain and the enzyme show positive cooperativity. It means that binding of the ligand to the enzyme will help other ligands to bind to the enzyme. Hill cofficient is used to measure the determining the degree of cooperativity of the binding between enzyme and substrate or ligand. As in this case, allosteric enzyme show positive cooperativity, its Hill cofficient will increase

<u>Answer</u>: predator and prey

<u>Explanation</u>:

The described graph illustrates the cycle of a predator and prey population.  The population curves for predator and prey are not synchronized with each other and their amplitudes differ.

Changes in the prey population will not result in immediate or exactly identical changes in the predator population.

In the attached image, the red line represents the prey population and the blue the predator population. As it can be observed, when the prey population increases in size, the predator population size increases too.

However, this increase is not of the same size and is delayed in time. The predator population will continue to increase even though the prey population has started to decrease.

This has to do with the fact that the adult predators mated and gave birth when the food availability was still high. However, these new young individuals will not survive and reproduce due to decreasing prey. As the prey continues to decrease, more and more predators will perish.

The same cycle will then repeat over and over again.

Answer:

If this didn't help then vote me 1 star. Thanks.

Explanation:

Two groups of proteins, called cyclins and cyclin-dependent kinases (Cdks), are responsible for the progress of the cell the. A phosphatase is an enzyme that removes a phosphate group from a protein. Together, these two families of enzymes act to modulate the activities of the proteins in a cell, often in response to external stimuli. Rough the various checkpoints. What genes destroy cancerous cells?  The primary function of the p53 gene is to repair or destroy defective cells, thereby controlling potential cancerous cells. This type of gene is called an anti-oncogene or tumor suppressor gene Cancer growth blockers are also called cancer growth inhibitors. They are a type of targeted cancer drug.  Our body makes chemicals called growth factors that control cell growth. Cancer growth blockers work by blocking the growth factors that trigger cancer cells to divide and grow. There are many types of cancer growth blockers that work in different ways..
