What changes during a controlled experiment? A. A variable B. The results C. The conclusion D. The hypothesis

Biology
1 answer:
N76 [4]3 years ago
7 0

Answer:

Option B

Explanation:

The answer is option B or "the results." Wouldn't be option A because a variable depending on the type is tested during a experiment if you change the variable you have a whole other experiment going on, it wouldn't be option D because your hypothesis is a logically guess at the beginning of a experiment of what you think is going to happen and it doesn't change. It wouldn't be option C because the conclusion is at the end of the experiment after you finished testing, recorded the results, and found out if your hypothesis is correct meaning it doesn't change, leaving option B as your answer.

Hope this helps.

How might a substrate of the citric acid cycle block respiration when it is present in great excess
murzikaleks [220]
The substrate of the citric acid cycle which can block respiration when it is present in excess is MALONATE. Malonate inhibits respiration by competing with succinate dehydrogenase for its acitve site. Malonate binds to the active site without reacting, thus competing with succinate. This disrupts the cellular respiration in the cell.
