Question

4 what process best explains how a nerve cell and a muscle cell can both develop from the same fertilized egg? a differentiation b natural selection c selective breeding d genetic engineering

Explanation:

Differentiation is the process by which unspecialized cells become specialized. All cells in an organism start from a single - fertilized egg. Through differentiation, different cell types such as nerve and muscle cells are formed. Natural selection is related to survival and reproduction of organisms in an environment, selective breeding is used in agriculture for desired traits in plants and animals, and genetic engineering is the manipulation of an organism's genes in a laboratory.

Answer:

A. differentiation
