Are bunchgrass because they form a kind of ecosystem within the prairie.
Yes, because there is only so much weight it can hold.
The key processes in the fast carbon cycle include: Photosynthesis: the absorption of CO2 from the atmosphere (terrestrial plants) and from oceans (marine plants) to produce organic carbon structures. Respiration: the release of CO2 into the atmosphere, soil and oceans by animals as they exhale.
So we know that to transport materials in or out of the cell, we need to have access to both the inside and outside of the cell. This would require that the protein be a transmembrane protein that reaches both the inside and the outside of the cell.
So in this case, let's look at pore proteins. These are proteins that cross a membrane and act as a pore for the materials that need to cross the membrane.
One example of a pore protein is an aquaporin. These proteins aid in the transport of water into or out of a cell.
Therefore, the answer to your question is: A) Pore proteins.
Answer:
The nuclear envelope does not disappear in metaphase of mitosis, because it already did in prophase. ... The nuclear envelope needs to be broken apart so that the chromosomes can be found, aligned in the middle of the cell, and then pulled apart.
