Write a paragraph on how Blood Glucose goes with Negative Feedback
vagabundo [1.1K]

Answer:

Here are some explanations from 0nline so if you want rewrite in your own words

hope this helps  :))

blood glucose-

"The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels."

"If the blood glucose level is too low, the pancreas releases the hormone glucagon. This travels to the liver in the blood and causes the break-down of glycogen into glucose. The glucose enters the blood stream and glucose levels increase back to normal. This is an example of negative feedback."

body temperature-

" Body temperature is regulated by negative feedback. The stimulus is when the body temperature exceeds 37 degrees Celsius, the sensors are the nerve cells with endings in the skin and brain, the control is the temperature regulatory center in the brain, and the effector is the sweat glands throughout the body."

"Body temperature is controlled by the hypothalamus in the brain. If the hypothalamus detects that the body is too hot, the response is that the body begins to sweat to try and reduce the temperature back to the correct level."

"Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances."

"Negative feedback brings a system back to its level of normal functioning. Adjustments of blood pressure, metabolism, and body temperature are all negative feedback"

What are 2 ways in which gametes differ from somatic cells?
tatuchka [14]
Gametes are the cells in human body used for reproduction, such as sperms or eggs, and somatic cells are the other body cells, such as muscle cells, skin cells and all other.

First, they have different number of chromosomes. Gametes have only one set of chromosomes, while somatic cells have a complete 2 set of chromosomes. This is because fertilization requires 2 gametes joining together and this will help maintain the correct amount of chromosomes at last.

Second difference between them is that gametes are products of meiosis, while somatic cells are products from mitosis. Both are types of cell divisions but meiosis produces 4 genetically different cells while mitosis produces 2 genetically indentical daughter cells.
