The food bolus will then get digested in the stomach.
Specifically, only protein is chemically digested into short polypeptides under the enzyme pepsin. The gastric juice that contains pepsin is produced by the gastric glands. The stomach is very acidic. It has a pH value of around 2. This is because it has to make sure that only pepsin is functional and so as because hydrochloric acid is present.
Polypeptides are not yet the final form of protein, amino acids are. But the process of breaking down polypeptides into amino acid is yet to be done at this stage, so as the other digestion of e.g. carbohydrates or fat. They'll mostly be done in the duodenum, which is the next stage after the stomach.
<em><u>D. Bacteria do not have membrane bound organelles inside their cells, and eukarya do. </u></em>
Answer:
Among vertebrates, external fertilization is most common in amphibians and fish. Invertebrates utilizing external fertilization are mostly benthic, sessile, or both, including animals such as coral, sea anemones, and tube-dwelling polychaetes. Benthic marine plants also use external fertilization to reproduce.
= Fish
Explanation:
Answer:
Organisms have different proportions of bases in the DNA.
Explanation:
Option B is correct because different organisms have different proportions of bases in their DNA. This makes each species unique. This means that it is not possible for multiple species of have similar proportion of DNA bases.
Other options are incorrect because of following reasons:
1. All the genetic information cannot be universal among all organisms. Different species performs different functions and the genetic information differs accordingly.
2. All animals cannot have similar amount of bases in their DNA. Different animals have different bases.
3. The given table doesn't say that plants are least related. In fact, all organisms differs in terms of DNA bases proportion.
Answer:
<u>Polygenic therapies are more likely to show </u><u>unintended effects</u><u> in other regions of the genome likely resulting in harmful diseases.</u>
<u />
Explanation:
Gene therapy involves biotechnological techniques that add or remove gene sequences in the genome. These are typically used in eliminating harmful genes that cause genetic diseases or disorders and are generally thought to improve an individual's quality of life.
Polygenic traits are controlled by several genes. Similarly, polygenic diseases may be caused by variations in several gene sequences. These include hypertension, heart disease, and diabetes. Polygenic therapies are more likely to show unintended effects in other regions of the genome, leading to other deleterious disease-causing effects.
