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.

Answer:
The correct answer is - carbohydrates.
Explanation:
The four significant groups of macromolecules found in living beings are carbohydrates, lipids, nucleic acids, and proteins. carbohydrates comprised of carbon, hydrogen, and oxygen molecules, generally in a proportion of 1 : 2 : 1.
Living things use carbohydrates as their main form of energy. Carbohydrates are a class of macromolecules is essentially utilized as a quickly accessible energy source by living things.
Thus, the correct answer is - carbohydrates.
Answer:
Ecology can be described as the branch of biology which is related to the study of the interaction of an organism with other organisms and the environment. This study is important because both biotic and abiotic factors play a vital role in the existence of an organism. Abiotic factors such as soil type, food resources, water resources, amount of sunlight reflect which organisms will be able to live in an area. Biotic factors also influence the life of an organism just as the abiotic factors do.
