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"

To introduce a particular piece of DNA into an animal cell, such as that of a mouse, you would find more probable success with w
Lesechka [4]

The correct answer is option B, that is, electroporation succeeded by recombination.  

A usual method of presenting exogenous nucleic acids into cells is known as electroporation. In this, an electric voltage potential is used through a biological membrane, ultimately resulting in the formation of conducting hydrophilic pores. The process of electroporation is utilized for transporting or transfecting nucleic acids generally DNA within the cells, to make them articulate genes that would modify the genetic mechanism.  

The transfected DNA can get recombined or incorporated into the host genome or can remain in its own composition. Thus, the process of electroporation straightforwardly permits more recombination to take place.

Which of the following is an example of the endocrine system maintaining homeostasis? (3 points)
motikmotik

Answer:

C. Sending a message to the pituitary gland to start producing a hormone when the levels in the body are too low

Explanation:

It's not A, because that's the nervous system, not endocrine.

It's not B, because homeostasis = balance, and not stopping production isn't balance

It's not D, because that's the nervous system again.

The endocrine system governs hormones.
