Peyer patches are lymphoid nodules located in the walls of the small intestine.
Peyer patches are also known as aggregated lymphoid nodules, they are organized in the form of follicles and are round or oval and their surface is free of the villi and depressions that are present throughout the intestinal wall.
Peyer patches mainly consist of B cells and play an important part in the immune system by monitoring intestinal bacterial populations and controlling the development of pathogenic bacteria in the intestines.

The continental drift affects living organisms in that it causes changes in climates which puts selective pressure on organisms, causes changes in habitats, including when large amounts of shallow marine habitat were lost in the formation of Pangea. Additionally continental drift may cause an increase or decrease in competition among different species and also it happens so slowly that it does not affect living organisms

Answer:
D) Energy is required in order to maintain homeostasis--without a constant, organized internal state, the cell will die.
Explanation:
Homeostasis is the condition of relative stability that the body needs to perform its functions properly for the body's balance.
Despite changes that may occur in the body, internally or externally, homeostasis is the constancy of the internal environment (interstitial fluid). Keeping at an appropriate temperature (37º C) ensuring that the necessary changes to the body occur; and thus the cells of the body develop.
Because of homeostasis, cells need a constant supply of energy. That's because energy is needed to maintain homeostasis - without a constant, organized internal state, the cell will die.
The reaction of cellular respiration and fermentation substrate level phosphorylation occur in both glycolysis and the citric acid cycle.
This phosphorylation occurs in the cytoplasm of cell and in mitochondria. When the phosphorylation inside the mitochondria, it occur during Krebs cycle. In this reaction the molecules are broken down in presence of oxygen to produce energy.
In cytoplasm, the reaction occur during the glycolysis. It is the reaction to add a phosphate group to a molecule that is derived from ATP.
Krebs cycle this is also known as citric acid cycle (CAC). This is the reactions in which oxidation of acetic acid provides energy for storage in phosphate bonds.
