Sperm cells of the russian dwarf hamster, phodopus sungorus, contain 14
chromosomes. what is the total number of chromosomes that would be contained in
a normal, newly formed zygote of this species?
a.7
b.14
c.28
d. 42

The correct option is C) 28

Explanation:

Sex cells divide by the process of meiosis. Meiosis can be described as a type of cell division in which the daughter cells formed contain half the number of chromosomes as the parent cell. This is because when the sex cells from the female and male parent will unite then the zygote will possess the right number of chromosomes.

In the following scenario, the sperm cells of the Russian dwarf will contain 14 chromosomes which will unite with the egg of another Russian dwarf also having 14 chromosomes. As a result, a zygote will be produced having 28 chromosomes.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
