Describe the chromosomal difference between sex cells and a zygote (fertilized egg)/ body cells

The main difference between sex cells and zygote is the chromosomal charge, where the sex cells have half of the chromosomes haploid and the zygote has the full load, is diploid, as well as the body cells.

Explanation:

Ploidy is based on the number of chromosomes found in a cell:

The reason for this difference is that the gametes go through a process of reductional division, called meiosis. They are haploid because when the gametes of the parents unite —during fertilization— they give rise to a haploid cell, the zygote.

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.  

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.
