Answer:
The onion cell has a cell wall, unlike the human skin cell.
Explanation:
Only plant cells have cell walls.
Answer:
C. It harms aquatic organisms
Explanation:
The hydropower is a one of the most commonly used in the world. It is based on the power of the water, and by building a dam on a river, the water is accumulated, and its power used for production of electrical energy. While this type of power has lot of advantages, like having long lifespan, being eco-friendly, and it has high efficiency, it also has some negatives about it. The biggest negative by the hydropower is that it causes harm tot he aquatic organisms. Because there is a dam built, the water becomes more stagnant, meaning that it becomes warmer, harming the organisms that are not able to adapt to it. The dam restricts the migration of the aquatic organisms, which is especially a big problem for the ones that migrate because of mating. The nutrients start to concentrate in front of the dam, while after the dam they are in very low quantity.
Aminopeptidases are enzymes that cleave polypeptides, or proteins,at the N terminus, or the amino end. Protein hydrolysis is breaking down proteins into amino acids by adding water. Aminopeptidases are enzymes that cause protein hydrolysis. Once the protein is broken down into amino acids, the amino acids can be metabolized. Usually the body uses carbohydrates or lipids for metabolism, but in rare cases, such as starvation, proteins can be broken down and used for energy.
Protein metabolism starts with the enzyme,pepsin, in the stomach and the smaller polypeptides travel to the small intestine where trypsin and chymotrypsin break them down into amino acids. Most of the newly available amino acids are combined to form new proteins. If the body has no need for proteins, they are converted to glucose or ketones and are decomposed. Breaking down amino acids results in nitrogen, which is converted to urine. In starvation, protein is broken down to amino acids and amino acids are broken down to oxaloacetate acid, pyruvate and acetyl coA and these intermediates are used in the Kreb cycle to produce ATP.
It means that you can adapt to the conditions around you. I hope this helped you out! <span>(っ˘ω˘ς )</span>
