A species of lizard is found on the eastern and western sides of part of a mountain range. On both sides, individual populations are small. On the western side, individual populations are relatively close together and males move extensively among populations to breed. On the eastern side, however, populations are farther apart and males seldom move among more than one or two adjacent populations to breed. If you were to study the genetic diversity of western and eastern populations, which pattern would you expect to find?

What is the main function of the reproductive system?

Answers

The major function of the reproductive system is to make sure that the human species survives. It is not necessary for every human being to produce children, but in order to continue our human species, at least some people have to have children. The four main functions of the human reproductive system are: To produce egg and sperm cells, to transport and sustain these cells, to nurture the developing offspring, and to produce hormones.
All of these functions are divided by their primary and secondary, or accessory, reproductive organs. 

Hope this helps and good luck :)

Answers

The answer is (c.) They take the form of sporangia.

The Oomycota or Oomycetes is also known as water molds. In 1840, this type of genus ravaged some parts of Europe especially in Ireland. It is called the Irish Potato Famine.
