Answer: E. Polygenic

Explanation: The color of eyes and hair is due to quantity and accumulation of pigments such melanin. Melanin is synthesize by multiple enzymatic steps and every enzyme is codified by a different gene. That means polygenic inheritance, that several genes are implicated in determined the this trait and its difficult to trace since every gene has a sequence that can vary between families or human groups.

Snowcat [4.5K]

Biological processes that systematically vary over a 24-hour cycle are called circadian rhythms and are regulated by a cluster of neurons called the suprachiasmatic nucleus.

<h3>What is the circadian rhythm?</h3>

The circadian rhythm refers to the biological process regulated by the duration of a calendar day, which is common for many organisms ranging from animals to plants.

The circadian rhythms enable the maintenance of homeostatic control of physiological functions and thus perform metabolic activities.

In conclusion, biological processes that systematically vary over a 24-hour cycle are called circadian rhythms and are regulated by a cluster of neurons called the suprachiasmatic nucleus.

Elena-2011 [213]

Answer:

Option (1).

Explanation:

DNA (deoxyribo nucleic acid ) is the genetic material present in all the organisms except some viruses. DNA structure follows the Chargaff's rule.

Accoprding to Chargaff's rule, the ratio of purines to pyrimidines in a DNA molecule is equal to 1. The amount of guanine is nearly equal to the amount of cytosine whereas the amount of thymine is nearly equal to the amount of adenine.

Thus, the correct answer is option (1).
