Answer:
The primary site for ribosome assembly
Explanation:
The nucleolus is a dark-staining spherical body, but it is found within the nucleus, not in the mitochondria. New ribosomes are assembled in the nucleolus, specifically the subunits of the rRNA or the ribosomal RNA. It is the biggest structure within the nucleus and can be seen during interphase. Interestingly, studies have shown that the size of the nucleolus can determine the life span of the cell.
A constant variable would be an element that remains unchanged and constant throughout the course of the experiment / investigation.
Answer:
A typical fire regime for a boreal forest might have fire re-occurring every <u><em>53 years.</em></u>
Explanation:
The fires caused in the boreal region adds essential nutrients to the soil. Some tree species are even dependent on the heat from fire to disperse their seeds, and the natural burn cycle helps maintain a healthy forest ecosystem. On average, wildfires burn anywhere between 5 to 20 million hectares of boreal forest each year. In Russia, low to moderately intense surface-level fires return every 53 years; for Canada, the return interval is roughly 180 years.
Answer:
Pollution that runs off the land often combines with the sediments at the bottom of the ocean or other types of water. In this way, fish may become poisoned. This is an example of how fish interact with the following are types of rocks that make up the lithosphere exceptThe amount of carbon dioxide in the atmosphere would greatly increase the population .
