Answer:
The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. These hormones regulate the body's growth, metabolism (the physical and chemical processes of the body), and sexual development and function.
Explanation:
The endocrine system is responsible for regulating a range of bodily functions through the release of hormones.
Hormones are secreted by the glands of the endocrine system, traveling through the bloodstream to various organs and tissues in the body. The hormones then tell these organs and tissues what to do or how to function.
Some examples of bodily functions that are controlled by the endocrine system include:
metabolism
growth and development
sexual function and reproduction
heart rate
blood pressure
appetite
sleeping and waking cycles
body temperature
Endocrine system organs
The endocrine system is made up of a complex network of glands, which are organs that secrete substances.
The glands of the endocrine system are where hormones are produced, stored, and released. Each gland produces one or more hormones, which go on to target specific organs and tissues in the body.
The glands of the endocrine system include:

I don't think we can say for sure. The crystal clear odor free water is probably safest to drink, but it could have some sort of poison mixed in it. And the semi cloudy green water is probably bad to drink, but it could just be vegetables making the water look green and cloudy.
Answer:
A
. the fertilized egg and the cells produced by the first few cell divisions
Explanation:
Totipotent cells are those cells in developmental stage of multicellular organisms which can give rise to any part of the organism. It can give rise to both the placenta and the embryo.
After the fertilization, the cells produced in first few divisions are totipotent. This stage is also called as morulla stage. Once blastocyst stage is reached, totipotency is lost. All the cells of blastocyst are not totipotent. The inner cell mass of blastocyst is pluripotent which means it can give rise to the entire embryo except placenta. The trophoblast layer of blastocyst can only produce placenta.
Answer:
Cells undergoing mitosis just divide once because they are forming two new genetically identical cells where as in meiosis cells require two sets of divisions because they need to make the cell a haploid cell which only has half of the total number of chromosomes.
