Can I see the picture please?
Just by reading the answers it seems like the correct one would be A, but i would like to double check.
Oxygen will diffuse more quickly into cell B because the diffusion gradient there is steeper.
The concentration gradient depicts the slow change in the concentration of solutes found in a solution between the two regions. A gradient in biological terms arises due to an unequal distribution of ions across the membrane of the cell. Both the process of facilitated and simple diffusion take place when there is a concentration gradient.
Answer:
C)
Explanation:
Bacteria are prokaryotic, which means they (generally) don't have organelles or a nuclear envelope around their nucleus. They have ester linkages in the phospholipids in their cell membranes, while archea, which are also prokaryotic, have ether linkages. Ether linkages are more chemically stable than ester linkages, and since archea live in extreme environments this is helpful.
Bacteria are not multicellular and do not have organelles (complex cellular structures) besides ribosomes.
They are animal organelles that remove wastes from the cell
The new hypotheses proposed by different scientists are often criticized by the others because these new hypotheses contradict the ideas and hypotheses that already exist. Adapting one's mind to a new hypotheses explaining a past event is often difficult when more clear hypotheses were already given earlier. Thus, the hypotheses suggesting the extinction of the dinosaurs are difficult for the scientific community to accept.
