Hi There!
Tell me a little about prokaryotic and eukaryotes.
What do these types of cells have in common?
How are they different?
2 very common similarities between the types of cells is that they both have a certain type of structure and all cells have a plasma membrane, DNA, ribosome, etc. They are different in a way that eukaryotes have a "membrane-bound organelle" which usualy includes it having a nucleus. Whats cool is that eukaryotes can be multicellular or singled celled> For Example, plants, insects, and fungi. Prokaryotes don't have a nucleus or organelle (membrane bound).
Hope This Helps :)
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.
