Answer:
No.
Explanation:
When the set of chromosomes are duplicated, it means the chromosomes will be double the number.
However the genetic information will not change. It will remain the same.
Duplication of chromosomes is usually occurs among the interphase stage of mitosis where chromosomes will duplicate to ensure the formation of two identical daughter cells.
In these cells there will be no addition or variation in genetic information.
Answer:
I believe the answer is B

Can you explain a little more about the question please?
Answer:
d. it diffuses into mitochondria to be broken down to generate ATP
Explanation:
When enough oxygen is available in the muscle cells, pyruvate produced by glycolysis enters the mitochondrial matrix. Once inside the mitochondria, pyruvate is decarboxylated into acetyl CoA. The reaction is catalyzed by the enzyme complex pyruvate dehydrogenase. Acetyl CoA then enters a sequence of reactions called Kreb's cycle and is broken down into CO2 and H2O. The energy released during these reactions is stored in the form of NADH and FADH2.
The NADH and FADH2 are oxidized by giving their electrons to O2 via electron transport chain. During this oxidation, the proton concentration gradient is generated across the inner mitochondrial membrane which in turn drives the process of ATP synthesis.
A is a correct answer.
Dermis is does not had contain significant amounts of the protein collagen.
Hope it helped you.
