When it's hot or when the organism starts sweating a lot, this causes an amount of water to be lost from the body. Water is important for the organism to survive and it's absence wi lead to death, therefore Osmoreceptors cells in the hypothalamus in the brain, sends signals to increase the rate of water re-absorption by the kidney. This causes the urine to be of a low volume and more concentrated. This allows enough water to be used by the body as a lot has been lost during sweating.

The Cell to Mentee
A cell is the basic unit of life of a human. The body cell contains cytoplasm in which organelles are present . There is a nucleus found in eukaryotic cell. It contains the genetic material in the form of DNA with proteins and chromosomes. Inside there is nuclear membrane. Outside the nucleus, there are many other organelles like mitochondria, ribosomes, golgi apparatus, endoplasmic reticulum, and many more.
Answer:
nuclear membrane, endoplasmic reticulum, Golgi apparatus, and vesicle
Explanation:
The structures or organelles in internal membrane system in the cell do all production, processing and secretion function together. A prokaryotic cell does not contain any membrane bound organelles but Eukaryotic cells do have. Nuclear membrane has double membrane and golgi-rendoplasmic reticulum and vesicle contain single membrane so all these organelles are membrane bounded.
