1. How does gene activation lead to cell differentiation? A. Different genes are activated in different cells, causing each cell to have a unique function.
B. The same genes are activated in every cell of your body, causing every cell to function the same.
C. Certain cells only have parts of DNA that cause cell differentiation,
D. Unique genes are in different cells, causing each cell to have a unique function.

Which is the correct answer and why? Also write why the others are wrong.

the question isn't complete here so i can't right an answer '_'

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

it's false. hope i .
