Answer:
Origin of Viruses. ... Small viruses started as runaway pieces of nucleic acid that originally came from living cells such as bacteria. Large viruses were once parasitic cells inside bigger host cells. Over time, genes needed to survive and reproduce outside host cells were lost.
Diffusion has a major part in this. It has proteins embedded in it that allow molecules to diffuse in and out of the cell up and down its concentration gradient.
Answer:
The correct answer is D increasing the activity of protons pumps that lowers the pH of the cell walls allowing cells to elongate.
Explanation:
The plant growth hormone auxin work by increasing the H+ ion concentration thus decreasing the pH of the apoplast.
The decrease in the pH of the apoplast helps in the cell wall extension that ultimately result in cell growth.
Auxin hormone exert this effect by increasing the activity of increasing the activity of proton pumps in the apoplastic membrane.
