Organisms that reproduce sexually recieve genetic material from both parents when fertilization occurs. the development of the zygote into a multicellular organism is the result of a) meiosis followed by mitosis b) mitosis and cell differentiation c) meiosis and cell differentiation d) protein synthesis followed by meiosis

The correct answer is option b, that is, mitosis and cell differentiation.

Explanation:

A zygote refers to the outcome of fertilization. The diploid zygotes go through the process of mitosis and differentiation in order to generate the embryos. The differentiation of cells at the time of embryogenesis is essential for the cell, organ, tissue, and organism identity.  

Once the process of fertilization takes place, that is, the fusion of sperm with the egg, the development of zygote takes place. The zygote differentiates into various kinds of cells by the process of mitosis, initiating the beginning of embryonic differentiation.  

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
