The answer is <u>B: a mutation inhibiting human immunodeficiency virus from entering the host cell</u>
The correct answer is (a.) moderate temperatures. The moderate temperatures allow Earth to maintain bodies of water into its normal state. Changes in the bodies of water in terms of volume and structure would change due to the change in temperature.
I know this might sound like a dumb answer but it could be your answer <span>They are both very hot</span>
I answered the question before but ill try to explain more. You know after 5 seconds they are going 60km/h, if you want to know how many km/h they are going per second (that would be their acceleration) you would take how fast he is going after those 5 seconds (60km/h) and divide it by how many seconds it takes him to get to that speed (5sec) and your answer would be how many km/h they can get to in one second (their acceleration).
Positive feedback: breast feeding, giving birth, and blood clotting are two examples.
Negative feedback: Blood glucose levels, temperature control, and body temperature are two examples.
-Negative feedback: accumulation of an end product of a process slows that process.
-Positive feedback: the end product speeds up its own production. Regulation is important because without it we would bleed out from small cuts because we wouldn't be able to form blood clots. Or we wouldn't be able to form ATP. Regulatory mechanisms help us do the important tasks needed to sustain life.
Hope this helps! :)
