Hey Brainly Student!
I found this in wonderopolis.org: “Scientists concluded that the average human body contains approximately 37.2 trillion cells! Of course, your body will have more or fewer cells than that total, depending upon how your size compares to the average human being, but that's a good starting point for estimating the number of cells in your own body!”
This is an estimation and there is not an exact amount because everyone is different :)
Answer:
Beaker A= Isotonic
Beaker B = Hypotonic
Beaker C= Hypertonic
Explanation:
ISO means the same on each side.
Hypo means less.
Hyper means more.
Answer:
Negative feedback mechanism
Explanation:
Negative feedback mechanism occurs when the product or the output of a process inhibits the same process. When blood glucose level rises, body receptors stimulate beta cells in pancreas to release insulin. Insulin leads to uptake of glucose by cells, lowering the blood sugar levels. The lowered blood sugar level is again sensed by the receptors and they inhibit the secretion of insulin. Hence, insulin inhibits its own secretion by removing glucose from blood which makes it a negative feedback mechanism.
