Dark fur color appears to be an adaptation for mice living in dark environments, as both the frequency of the characteristic and the allele that generates it have altered. These findings further back with the theory that selection is context-dependent, as dark mice were preferred in some contexts but not in others.

What is mutation?</h3>
A mutation is defined as a change in the sequence of genetic letters, called bases, within a molecule of DNA.
In a population, more offspring are born than can survive, resulting in competition among people. Individuals that possess a certain trait are more likely to live and/or produce more offspring than those who do not possess that trait. The context in which a species exists influences its selection. Characteristics that are advantageous in one setting may be detrimental in another.
New mutations cause black color.
- Fur color is controlled by many genes (4:29).
- Most genes are identical, but dark and light rock
- pocket mice differ in one gene (Mc1r; 4:55).

Answer:
A) Calcitonin injection
Explanation:
Parafollicular cells or C-cells of the thyroid gland produce a hormone which is involved in the regulation of calcium levels in the blood. This hormone is Calcitonin. It works in an antagonistic manner with the Parathyroid hormone (PTH). Calcitonin decreases the calcium level in the blood by increasing absorption of calcium ions in bones. In osteoporosis, when the patient is given the injection of hormone calcitonin, it produces and increase in bone mass because it negatively affects the rate of absorption of bone by the osteoclasts.
Answer:
Merkel cells located in the epidermis.
- It is called sensory function.
- The Merkel cells send information to the brain about temperature and touch.
- After brain decode that we can feel it.
