Answer:
Dissolved oxygen concentrations are constantly affected by diffusion and aeration, photosynthesis, respiration and decomposition. While water equilibrates toward 100% air saturation, dissolved oxygen levels will also fluctuate with temperature, salinity and pressure changes ³.
Relationship between oxygen uptake and dissolved oxygen concentration The potential for adverse effects of low DO concentrations on fish can be defined ...
Explanation:
Your answer would be C.It encloses the cytoplasm.
I think you forgot to give the options along with this question. I have researched with the question and have found the options as well. Hope it helps you in your study. Among the choices that i have come up with, the option that says that temperate deciduous forests are less open than tropical rain forests.
Answer:
A
Explanation:
The restriction enzymes cut the isolated DNA into fragments
The answer is diffusion.
The most important mechanism that enables oxygen and carbon dioxide (but as well other small molecules such as glucose, amino acids, wastes) across capillary walls is diffusion. Diffusion is a net movement of molecules through some barrier from an area of high concentration to the area of low concentration. When blood rich in oxygen reaches capillaries close to the cell, now there <span>is </span>more oxygen in the capillaries than in the cells and by diffusion, oxygen will pass capillary walls and enter the cell. Since blood in capillaries lacks in carbon dioxide, it will easily leave the cells and enter the blood. It should be taken into consideration that capillary walls may be fenestrated, continuous, and discontinuous which can affect movement through them.
