What characteristics of dna results in cell differentiation in developing embryos? a. what protein is produced by a gene. b. which genes are active. c. how many copies of each gene are present. d. which genes are present.

Hi!

The correct option is B. Which genes are active.

Embryonic differentiation is a developmental process by which embryonic cells give rise to specialized cells and a diverse range of tissue structures. All of this unique cells essentially rise from a type of cells that are known as pluripotent cells.

But how do these pluripotent embryonic stem cells know which cells to differentiate into? This is where genes come into play. The cell has an inherent signalling ability that determines which gene is to be active and expressed. These specifically activated genes then translate into proteins for which it is specific, giving each cell, tissue and organ its particular identity.

Hope this helps!

the answers are a and c

its temperature is increasing. this causes molecular vibrations to increase.
