<span>One of the key ideas in biology is that structure always impacts function. For one, a neuron has a long axon because it helps to transmit signals from cell to cell, allowing the nervous system to function. Secondly, epithelial cells are long and thin, which allows them to cover numerous organs in the body. Finally, muscle cells are more rod-shaped and are comprised of contractile units which allows them to withstand the wear and tear of muscle movement.</span>
A vacuole
is responsible for temporary storage for water, waste products, food, and other cellular material.
Explanation:
Vacuoles are storage bubbles found in cells. They are found in each animal and plant cells however are a lot of larger in plant cells. Vacuoles may store food or any form of nutrients a cell may got to survive. they'll even store waste merchandise that the remainder of the cell is shielded from contamination.
Answer:
Inducible
Explanation:
When a gene is expressed only under certain conditions such as the presence of an inducer in the environment to inactivate the repressor, the gene expression is said to be inducible. Here, the presence of substance Y is required as it serves as an inducer by inactivating the repressor protein. When the repressor protein is inactivated, RNA polymerase is able to express the gene. This is an example of inducible gene expression. For example, the presence of lactose is required for the expression of genes of the lac operon.
Answer:
Microarray technology is a very useful technology that allows to study the measure the expression levels of large numbers of genes simultaneously. It consists of a solid support (that can be glass, silice, or nylon), and to it are attached a lot of single stranded DNA fragments that acts like probes. By complementarity, the genes corresponding to this probes that are being expressed at some time will attach to it. Probe-target hybridization is usually detected and quantified by detection of a fluorophore compund, a silver stained, or chemiluminescence-labeled targets.
The answer is fifth. This is because the increase in expenditure is reflected in the increasing cost to the federal and state governments of operating the Medicare and medical programs as well as in the increase in out-of-pocket payments made by the elderly. As a consequence health care financing has become one of the more critical policy issues to be addressed.
