Natural selection is when favorable traits stay in a population while unfavorable traits get weaned out. EX: There is terrain that is lightly colored and there are some moths there. They need to blend into the terrain to not be eaten by birds. So, the lighter colored moths live longer and can produce more offspring than the darker colored moths. Now, what happens if the color of the terrain changes due to a factory being put right next to it and causing the terrain to turn grey. The lighter colored moths will be eaten more than the darker colored moths so then he darker colored moths will be reproducing more and most of the moths will be darker colored.
Artificial selection:<span> is the intentional breeding for certain traits, or combinations of traits, over others, and is synonymous with "Selective breeding".
EX: the breading of certain dogs to produce the poodle.

To maintain body homeostasis
Explanation:
The endocrine system consists of the endocrine glands that release hormones directly int the blood. Those hormones bind to their receptors on the target cells and thus regulate their function. The major glands are:
pineal gland-releases melatonin, controls sleep cycle
pituitary gland-control growth, blood pressure, thyroid glands and metabolism etc.
pancreas-secretes insulin and glucagon, control of blood sugar levels
ovaries, testes-reproductive role (release female and male hormones)
thyroid gland-controls metabolism and protein synthesis
parathyroid gland-controls Ca levels
hypothalamus-connects nervous and endocrine systems, controls other glands
adrenal glands-release adrenalin and steroid hormones.
An excretory system that is partly based on the filtration of fluid under high hydrostatic pressure is the kidneys.
The paired kidneys are frequently regarded as the primary excretory organs. The generation of urine, a liquid waste product, by the kidneys serves as the body's main method of excreting extra water and waste from circulation.
What are kidneys?
- Excretory systems maintain the right concentrations of water, salts, and nutrients while eliminating metabolic wastes to regulate the chemical composition of bodily fluids. In vertebrates, this system is made up of the kidneys, liver, lungs, and skin.
- Kidneys are the vital organ of the human body.
- Kidneys helps in removing wastes and extra fluids from the human body.
- Kidneys helps in removing acid from the body, which maintain the balance in the cell.
- Kidneys also helps in regulating and filtering the blood.
- Kidneys helps in synthesizing the cells, which makes blood cells.
- Kidneys helps in regulating the blood pressure.
