Answer: c
Explanation: it dose not matter
When antibiotics attacks a bacteria first the growth of bacteria is stopped and the bacteria will become unable to divide and spread throughout the body via the bloodstream and aortic arteries. An antibiotics' main job is to stop the growth of bacteria and other foreign entities inside our body, such as a virus, fungal spore, parasites, and other dangerous and potentially deadly protozoa, so as to prevent the body from harm that may be fatal.
On cellular level, antibiotics chemically damage the bacteria or targeted organism's DNA and alter it in such a way that they will become unable to divide any further and thus become unable to reproduce and eventually die off as the white blood cells engulf the decaying organism's body, so it doesn't become dangerous.
Answer: A, a structure that has no use in the organism
Explanation:
A vestigial structure is an anatomical feature that no longer seems to have a purpose in the current form of an organism of the given species.
The black coat allele will be represented as the capital letter over the lowercase letter in guinea pigs. When crossing, you get 25% for homozygous dominant, 50% for heterozygous dominant, and 25% for homozygous recessive.
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.
