I will mark brainliest!! THANK YOU! Students are discussing differentiation of cells in an organism. Which student has to most accurate description of differentiation?

Student 2

Explanation:

I think it is student 2 because differentiation is the dividing and changing of embryonic stem cells into cells that are specialized in structure and function. Some stem cells form liver cells, some heart cells, muscle cells.

 Student 1: differentiation occurs during reproduction.

Explanation:

The process of cell differentiation starts with the fertilization of the female egg. As soon as the egg is fertilized, cell multiplication is initiated resulting in the formation of a sphere of cells known as the blastocyst.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
