Food chains don’t have infinite links, because only about 10% of energy is passed upwards in trophic levels. So a mouse could eat 10 grasshoppers, but a hawk would need to eat 100 mouses to get the same energy
Answer:
The sentences can be completed as follows:
The enzyme lactase breaks down the sugar lactose.
If the body doesn’t produce much of this enzyme, people have what’s called lactose intolerance.
During the chemical reaction the enzyme doesn’t get used up, but gets reused.
Enzymes are substances that speed up chemical reactions which are also known as catalysts.
Explanation:
Enzymes can be described as molecules which act as biological catalysts i.e they are involved in speeding up a chemical reaction. The enzymes do not get used up in a chemical reaction and hence, they can be reused.
Lactase is an enzyme which helps in breaking down the sugar lactose which is commonly found in the milk. If enough lactase is not produced by a person's body, then he/she becomes unable to digest the sugar lactose. Such a condition is known as lactose intolerance.
I do believe that it is C. crossing over :) I hope that is correct, it seems like the only plausible answer.
Answer:
The correct answer is "stress relaxation response."
Explanation:
Smooth muscle cells relaxes after being stretched which is called "stress relaxation response". If we explain it a bit further, smooth muscle cells lack gap junctions and because that contraction of a single cell doesn't spread to adjacent cell resulting with no strong contraction.
