Answer:
The correct answer is option Complex neuroendocrine response.
Explanation:
Hypothalamus is the thermostat of the body as it regulates and maintains body temperature by responding to external signals or stimuli and adjusts the body temperature in a close one to two degree of 98.6 degree.
The regulation involves a different type of endocrine hormones and thyroid gland and receptors that help in signaling the increase or decrease of body temperature it involves neurons and hormones.
Due to the response of thermoreceptors and hormones is known as the neuroendocrine response. Hypothalamus Involves two or more hormones and several steps it known as a complex response.
Thus, the correct answer is a Complex neuroendocrine response.
The correct option is (a) 2 → 4 → 1 → 3
A change occurs in the environment. → Poorly adapted individuals have decreased survivorship. → Well-adapted individuals leave more offspring than do poorly adapted individuals. → Genetic frequencies within the population change.

What is genetic variation in population?</h3>
- The presence of various alleles, or different gene versions, within a population indicates genetic variety.
- If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
- Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.
