Answer:

d generate offspring that carry parental genes

The use of restriction enzymes and electrophoresis to generate a map of the DNA molecule is known as RESTRICTION MAPPING. This technique is used to map an unknown fragment of DNA.

Restriction enzymes are enzymes that cut a DNA fragment at specific nucleotides sites, thereby generally smaller fragments of DNA.

Restriction mapping is a strategy used to map unknown fragments of DNA by digesting them into smaller fragments and then identifying the specific sites of the DNA breakpoints.

Restriction mapping can then be used to create a diagram of fragments of DNA marked with specific sites where they are cut by specific restriction enzymes.

a. Testosterone gland  

Explanation:post protected

Testosterone gland is not an accessory gland of the male reproductive system.

Testosterone is a hormone that is primarily produced in the testicles in males and in small amounts in the ovaries and adrenal glands in females. It is a vital hormone that plays a critical role in the development of male reproductive tissues and secondary sexual characteristics, such as muscle mass, bone density, and body hair growth.

Testosterone is also essential for maintaining sex drive and overall physical health in both men and women. The production of testosterone is regulated by the hypothalamus and pituitary gland in the brain, which release signals to the testes to produce testosterone.

Certain medical conditions, lifestyle factors, and aging can affect testosterone production and levels, which can have significant impacts on health and wellbeing. Treatment options are available to address testosterone deficiencies and imbalances.

Explanation:

For plants, light is an external stimulant. Phototropism is a response to light that plants have. The plant responds by orienting its growth in the direction of the light.

A stimulus is an occasion or any change in the environment that causes an organ or tissue to have a certain functional response.

An external or internal trigger is possible. Sensitive to external stimuli like sound and touch are sense organs like the ear and sensory receptors like those in the skin.

Direct one-to-one stimulus-response reactions are the most basic sort of response. The stimulus is a change in the environment, and the response is how the organism responds to it.

A stimulation that comes from outside the organism is known as an external stimulus. Light is one example of an outside stimulation. Although it comes from outside the body, it has an impact there as well.

Thus, it can be concluded that light is an external stimulus.

Answer:

The correct answer is C (The change of color allowed them to hide better from predators)

Explanation:

Before, the deer mice were easy prey for predators since their color stood out and the predators could find them. Therefore, the change of color allowed them to hide better from predators. You may be tempted to answer a, but if you read carefully it says "The change of color camouflaged them, which helped them HUNT better." Clearly A is wrong since deer mice don't really hunt.
