Should be A the newer layers are usually on top
Answer:
All human beings are 99.9 percent identical in their genetic makeup. Differences in the remaining 0.1 percent hold important clues about the causes of diseases.
The experiment by Peter Agre who discovered the protein Aquaporin demonstrated the function of proteins that allow facilitated diffusion of water.
Explanation:
Aquaporins are water channel proteins that facilitated diffusion of water. Agre was able to prove its function when a frog’s oocytes showed increased water permeability when an unknown protein (membranous) from the RBCs was introduced into them. The oocytes without proteins did not facilitate water diffusion.
Aquaporins are membranous proteins that belong to larger intrinsic proteins but act as pores on the cellular membranes to facilitate water diffusion.
Answer:
the genetic code is being carried by the Dna molecules, which is in most organisms
Answer: A- Disruptive selection
Explanation: Disruptive selection increases genetic variation as the population begins to be more different when selection existing in nature chooses multiple phenotypes reaching the highest degree which each have particular benefits. However, they tend to make single-celled life form that has interposed characteristics to produce smaller offspring while allowing the organisms that have the highest degree of characteristics to produce more offspring.
