Question

based on figure 1, which statement best describes how the skin cells and muscle cells of an elephant form? a. skin cells and muscle cells form from the same group of cells, but the cells in that group were originally different types of cells. b. skin cells and muscle cells form from different groups of cells, but each group originally came from the same cell. c. skin cells and muscle cells form from the same group of cells, and the group started out as a single cell. d. skin cells and muscle cells form from different groups of cells, each of which started out as a different single cell.

Explanation:

All cells in an organism originate from a single - celled zygote. Through cell division and differentiation, different types of cells such as skin and muscle cells are formed. Skin and muscle cells come from different cell lineages that ultimately trace back to the original zygote.

Answer:

B. Skin cells and muscle cells form from different groups of cells, but each group originally came from the same cell.
