Why is it impossible to predict the phenotype of the offspring by observing only the phenotype of the two parents?
igomit [66]

Because some trait's phenotypes don't indicate their genotypes so in order to predict the phenotype of the offspring you have to know the genotypes of the parents

Which structures are highlighted? Which structures are highlighted? duodenal glands Peyer's patches (aggregated lymphoid nodules
lilavasa [31]

Answer: (<u>Note</u>: You will find the image with the highlighted structure in the attached file)

Peyer's patches (aggregated lymphoid nodules)

Explanation:

Peyer's patches are anatomical regions located under the mucosa of the gastrointestinal tract, specifically in the lamina propria of the thin intestine. These patches are nodules or cumulus of lymphatic tissue and other accessory cells, and this is why they represent a huge part of the mucosa´s immunity system.

Peyer's patches belong to the group of lymphoid tissue associated with the intestine, composed of lymphoid follicles distributed along the gastrointestinal tract.

A lymphoid follicle is a cumulus or aggregate of lymphoid cells that do not have a well-defined structure nor organization. In general, these follicles are isolated from each other in the intestine. But in the terminal ileum (The last portion of the thin intestine) they get so close that they might form a plaque.  The Peyer´s patches are formed principally by lymphocytes B that synthesize immunoglobulin A, which has an important role in immunity.

Describe how the output of the Krebs cycle can be modified in additional processes of the carbon cycle.
Murljashka [212]

Answer:

Step 1. A carboxyl group is removed from pyruvate, releasing a molecule of carbon dioxide into the surrounding medium. (Note: carbon dioxide is one carbon attached to two oxygen atoms and is one of the major end products of cellular respiration. ) The result of this step is a two-carbon hydroxyethyl group bound to the enzyme pyruvate dehydrogenase; the lost carbon dioxide is the first of the six carbons from the original glucose molecule to be removed. This step proceeds twice for every molecule of glucose metabolized (remember: there are two pyruvate molecules produced at the end of glycolysis); thus, two of the six carbons will have been removed at the end of both of these steps.

Step 2. The hydroxyethyl group is oxidized to an acetyl group, and the electrons are picked up by NAD+, forming NADH (the reduced form of NAD+). The high- energy electrons from NADH will be used later by the cell to generate ATP for energy.

Step 3. The enzyme-bound acetyl group is transferred to CoA, producing a molecule of acetyl CoA. This molecule of acetyl CoA is then further converted to be used in the next pathway of metabolism, the citric acid cycle.
