A researcher is trying to design an experiment to measure the amount of energy a person uses during different activities. He pro
Tomtit [17]

The right answer is to measure the amount of released carbon dioxide.

The carbon dioxide exhaled by the lungs can reflect the energy consumed by the body since it comes from the degradation of glucose which is the main energy substrate. And this is a better indicator of energy consumption than measuring heart rate because it can be inflected by several factors.


A is false because glucose is not found in the urine, except in the case of diabetes mellitus.

C is false because the consumption of calories does not mean that we will directly use it.

D is wrong because perspiration is independent of energy consumption, this is a way to cool the body after exercise.

Which statement about Earth's rotation and its revolution is correct?
Allisa [31]

Answer:

It takes Earth longer to revolve around the sun than to rotate on its axis.

Explanation:

The vocabulary can be tricky in this question. It is important to remember that the term revolution refers to something moving around a fixed point. In this case, the earth is the object revolving around sun which is the fixed point in the frame of reference.

Now, the earth rotates at a constant speed around its axis. This is what causes the day/night cycle. The earth itself is spinning, therefore we use the term rotate.

Given the mRNA sequence GGU-GCU-CCU-AUU, what would happen if a nucleotide was added at the fourth location in the chain? A. chr
anygoal [31]

Answer: The correct answer is B) Frameshift mutation.

The given  mRNA sequence is GGU-GCU-CCU-AUU. When a nucleotide is added at the fourth location in the chain, it entirely changes the frame from the insertion of the nucleotide till the end of the gene sequence. This is called a frameshift mutation.

This is because after adding a nucleotide, a new frame is generated that will code for different amino acids and therefore a different protein will be synthesized.

On the contrary, chromosomal mutation is an abnormality in the chromosome ( in terms of number or structure) whereas substitution mutation is the one, which exchanges one base with another. Deletion of base also results in the frame-shift mutation.
