Answer: The correct option is A (chromosome Number is reduced from diploid to haploid)
Explanation:
In sexual reproduction, offspring are produced by fusion of two different sex cells which usually come from two different parents. These sex cells are know as gametes.
Meiosis is a type of cell division that gives rise to gametes in which the chromosome number is halved. Thus, the gamete cell is said to contain a haploid number (n) of chromosomes.
A diploid cell has two sets of chromosomes: one from the male parent and the other from the female parent. When a diploid cell undergoes meiosis the following occurs:
--> the chromosomes replicate once and
--> the nucleus and cell duplicate ( divide equally) twice.
As a result, the diploid parent cell gives rise to four haploid gamete cells. Therefore the statement "chromosome Number is reduced from diploid to haploid ' is true concerning meiosis I.
The dermal blood arteries work in dermal papillae to hydrate the epidermal cells.
<h3>What are dermal papillae used for?</h3>
The term "dermal papilla" can also be (DP). It is described as the hair follicle of an epithelial progenitor cell's chemical and physical niche. The dermal papilla's main job is to produce the hair shaft and rejuvenate the cycling section of the hair follicle. Dermal papillae are important because they reinforce the bond between the dermis and epidermis and reduce friction-related damage in places that are often used. Moreover, The dermis has a rough appearance thanks to the papillae, which interlocks with the epidermis above it to reinforce the bond between the two layers of skin. The papillae produce epidermal ridges on the palms and soles. These epidermal ridges give rise to fingerprints.
