Explanation:
In population genetics, the term evolution is defined as a change in the frequency of an allele in a population. ... The allele frequency within a given population can change depending on environmental factors; therefore, certain alleles become more widespread than others during the process of natural selection.
Answer:
C- Bacteria become more resistant to antibiotics that are used to treat bacterial infections.
Explanation:
Selective breeding involves humans breeding plants and animals by choosing which animal or plant males and females will sexually reproduce and have offspring together. This is usually done to achieve a particular favorable phenotypic trait in the new offspring.
Bacteria become more resistant to antibiotics that are used to treat bacterial infections doesn’t undergo any selective breeding process by humans which makes it the right answer.
An environment that has all the things that particular plant or animal need in order to live is referred to as habitat.
<h3>What is Habitat?</h3>
This is an area where an organism lives and comprises of resources and factors which supports its survival.
Food, light etc are part of the resources in which a habitat has which ensures appropriate growth and reproduction of species.

Answer:
During the resistance phase of the general adaptation syndrome, the human body undergoes a process of adaptation or tolerance to stress, which requires an increase in levels of growth hormone (GH) and cortisol, so it is observed rise the levels of GHRH and CRH.
Explanation:
General adaptive syndrome is a product of the stress to which an individual is subjected, causing a number of symptoms reflecting the loss of normal body balance, symptoms that can be both physical and psychological. This syndrome has three phases:
- <em>Alarm phase.
</em>
- <em>Resistance phase.
</em>
- <em>Exhaustion phase.
</em>
The second phase, resistance, is due to an <u>adaptation or tolerance when the stressful stimulus is maintained</u>. At this stage, an increase in blood levels of growth hormone and cortisol -which contribute to the stress tolerance process- is usually observed, increasing the bioavailability of blood glucose and endogenous steroids.
Both GHRH (somatocrin) and CRH (corticotropin-releasing hormone) are produced by the hypothalamus and activate the release of GH and adrenocorticopotrotrope hormone (CRH) by the pituitary gland, producing:
- <em>Increased levels of circulating growth hormone, necessary to regulate metabolism, and increase the amount of blood glucose.
</em>
- <em>Increased levels of cortisol, from the adrenal glands, in response to stress. </em>
In the resistance phase of general adaptative syndrome, GHRH and CRH levels increase to regulate adaptive changes that occur in the body of the individual who has it.
