The hypothalamic−pituitary−adrenal system helps maintain balance in the body by directing the sympathetic nervous system, as well as the endocrine system, immune system and digestive system. The hypothalamic−pituitary−adrenal system mainly controls the cortisol levels and the sympathetic nervous system, but it also plays a role in regulating hormones in the endocrine system, and it moderates the immune system and the digestive system.
Answer:
Six examples of density-dependent limiting factors are:
1. Competition within the population.
2. Predation.
3. Disease and parasites.
4. Waste accumulation.
5. Energy supply.
6. Migration.
An endergonic reaction, like photosynthesis, refers to a reaction, which needs the energy to be driven. The activation energy for the reaction is usually greater in comparison to the entire energy of the exergonic reaction. The endergonic reactions are non-spontaneous.
In the given case, in order to accomplish the process, the coupling of the endergonic reaction, that is, thermodynamically unstable reaction with an exergonic, that is, the thermodynamically stable reaction is done so that the entire free-energy change of the coupled reactions becomes negative.
