Explanation:
Psi packaging Element is a cis-acting RNA element identified in the genomes of the retroviruses Human immunodeficiency virus (HIV) and Simian immunodeficiency virus (SIV) It is involved in regulating encapsidation of the retroviral RNA, an essential step in replication.
Answer:
its "C"
Explanation:
On our planet we can survive thanks to a layer of different composition of gases that surrounds the whole Earth. This layer remains on Earth thanks to gravity. It is the earth's atmosphere, and it is difficult to determine exactly its thickness, since the gases that make it up become less dense with height, until they practically disappear a few hundred kilometers from the surface.
The atmosphere fulfills various functions for life on the planet and without it we would not be able to have life as we know it.
Answer:
Por cada par de electrones transportados a la cadena de transporte de electrones por una molécula de NADH, se generan entre 2 y 3 ATP. Por cada par de electrones transferidos por FADH2, se generan entre 1 y 2 ATP
Explanation:
Answer:
Performing the ischemia/reperfusion experiment using neutrophil-depleted animals and examining whether the degree of tissue damage is reduced
Explanation:
Neutrophils are one of the important component of the white blood cells. Neutrophils has the ability to phagocytose the cell and these cells first reach at the time of parasitic infections.
In case of reperfusion experiment, the neutrophil cells can be used to obtain the best results. The variables that are used in the experiment can be tested and is limited in the absence and the presence of the neutrophil cells. The tissue damage can be diagnosed by this experiment.
Thus, the correct answer is option (B).
Answer:
The reactants and enzymes required for a particular biological process are concentrated in a particular organelle.
Slower
Explanation:
Enzymes are usually localized in organelles to make it easier for cellular processes to occur. Enzymes are NOT randomly distributed in the cell. Each organelle is capable of a specific function and uses specific enzymes to do these processes. Enzymes are very specific and only work for certain organelles, so they are appropriately distributed throughout cells to ensure biological processes can proceed appropriately. This is also why processes would run slower if they were just in the cytoplasm, because organelles have reactant-specific enzymes to do certain biological processes, which cannot be effectively done in the cytoplasm in the cell.
