DNA comprises the genetic makeup of every organism. It carries genetic information that is used by the organs in the body to determine what functions to carry out.
DNA cannot be used to see the nuclei of cells or absorb viruses. A person's personality cannot be determined from DNA.
The answer is D. to determine if people are related, as DNA between two people can be compared for similarities of code between the two.
For the first question, I would say a line graph. And the one about the human heart, I need some more information.

Explanation:
The source of the energy required to regenerate ATP is the chemical energy stored in food (e.g. glucose). The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP.
Answer:
Perfectly in theory, except there is chance involved
Explanation:
The Punnet square is a diagram that allows scientists to predict the possible outcomes of the offspring when the genotypes of the parents are known. This is in line with Mendel's principles, and from a theoretical point of view would match up perfectly. However, it all works based on <em>probability</em>.
However, inheritance is always down to chance. Of your parents 2 alleles, you always have 50:50 chance of inheriting one of the allele. Overall, this is what is predicted in punnet squares.
However, think about flipping a coin. There is always 50:50 chance of getting heads, but that doesn't mean it is impossible to flip a coin and get tails 10 x in a row. It is just less likely. So in reality, observations might deviate from the theory.
