Ahuman somatic cell contains 46 chromosomes. how many chromosomes are found in a human egg cell?

23 chromosomes.

Explanation:

Chromosomes are present in the nucleus of eukaryotic cells and their amount varies in each species. In humans, for example, they are distributed as follows:

Somatic cells (non-reproductive cells): 46 pairs of homologous chromosomes. These paired chromosomes are similar, and thus these cells can be called diploid and represented by 2n; Reproductive, germ cells or gametes (eggs): They have half of the somatic cell chromosomes, so they have 23 chromosomes. These cells unite in the reproductive process, giving rise to somatic cells with 46 chromosomes. When cells have only one set of similar chromosomes, they are called haploids and represented by n.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
