Answer:
Citric acid cycle also known as the Krebs cycle, is the second stage of the three-stage process by which living cells break down organic fuel molecules in the presence of oxygen to harvest the energy they need to grow and divide.
They are found in the center of the osteon within a long opening called the Haversian canal.

- By substitution, justify that x = − 6 is a solution to x − 2 = − x − 14.

First, let's substitute the value of x as -6 in the equation.

Now, let's solve it.

Subtract 2 from -6 to get -8.

The opposite of -6 is 6.

Subtract 14 from 6 to get -8.

Compare -8 and -8. We can see that both the LHS & RHS are equal to each other. So, hence we proved that <u>x = − 6 is a solution of x − 2 = − x − 14.</u>
Answer:
A control group setup in an experiment is used to see if there are other variables in play during the experiment. Say I was to test which type of blood is a shark's favorite, my control would be putting red paint in one of the set ups to see if the shark is just interested in the red color of blood, instead of the other types of blood.

Answer:
The correct answer to this question should be a drup called antibiotics.
In our case, we need to look for something that helps us deal with bacteria infection, or in other words, treating diseases caused by bacteria. A drup that interfers with viral DNA is responsible for treating a kind of virus that basically attack DNA to live. And I would consider the drug that moderates you use of sugar should be used to solve problem related to the amount of sugar in your body, maybe diabetes. Antibiotics is especially designed to kill bacteria, so it is the correct answer.
