Which type of human cells contain a half set of chromosomes (often written as n)?

Gametes are the type of human cells that contain a half set of chromosomes.

Explanation:

In superior organisms that reproduce sexually, such as human beings, the somatic cells are diploid (2n), which means that each cell has a pair of equal chromosomes. The somatic cells are all the body cells excepting for the sexual ones, and they reproduce by the process of mitosis. These cells have a set of chromosomes inherited from the maternal side and another homologous set of chromosomes inherited from the paternal side. Hence, the number of chromosomes in these double sets of the somatic cells are diploid, 2n.

In humans, there are also sexual cells, which are haploid (n). These cells are the gametes, and they reproduce by the process of meiosis. Gametes contain half the number of chromosomes that might be found in the somatic cells. The number of chromosomes in this set is haploid, n.

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
