Up to this point, did you notice any differences between the development of male and
female gametes?
Explain

Both male and female gametes are produced by different organs and in different sizes.

The main difference between male and female gametes is that male gametes which are known as sperm cells are produced in large numbers by the male reproductive organs whereas female gametes are called egg cells which are produced single at a time by the female reproductive organs.

Both male and female gametes are formed by meiosis type cell division. The female gamete is a large in size and motile while the male gamete is small in size and also motile so we can conclude that both gametes are produced by different organs, numbers and sizes.

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.

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.
