Answer:
The structure of mitochondria contains the foldings in the inner side called "cristae" which increase the surface area of the mitochondria. The cristae are important to mitochondria as well as cell as cristae embody the ATP synthase enzymes which help in the formation of the ATP molecules.
Heart cells require more energy to pump the blood from the heart to the body so it needs a more mitochondrial number in the cells with more infoldings to synthesize more ATP.
Answer:
The hershey chase experiment on bacteriophages showed the genetic information is carried in <u>DNA.</u>
Explanation:
In 1952 Alfred Hershey and Martha Chase provided evidence that DNA is the genetic material. These scientists carried out an experimental work with the T2 virus, a bacteriophage that infects the Escherichia coli bacteria, which reproduces by attaching itself to the outer wall of the bacteria, injecting its DNA into it where it replicates and directs, the synthesis of phage proteins. Phage DNA is encapsulated within proteins and produces phages, which lyse or break the cell and releasing phage from the progeny. They used radioactive forms (isotopes) of phosphorus and sulfur. A radioactive isotope can be used as a marker to identify the location of a specific molecule, because any molecule that contains the isotope is radioactive and therefore easy to detect. The DNA contains phosphorus, but doesn't contain sulfur, therefore phosphorus-32 was used to mark the DNA, instead the protein has sulfur, but not phosphorus, so sulfur-35 was used. Hershey and Chase found that sulfur-35 is outside the cell while phosphorus-32 was inside, indicating that DNA was the physical support of the inheritance. This work allowed the scientists to conclude that it's the DNA and not the protein that enters the bacteria during phage reproduction and that only the DNA is transmitted to the phage of the progeny.

Answer:
the human heart is a double pump with the right ventricle as pump one and the left ventricle as pump two. the heart a double pump functions as a double ventricle. the Blood moves from the body into the right atrium, and then into the right ventricle where it gets pumped into the lungs. Blood gets oxygenated in the lungs, moves into the left atrium, and into the left ventricle and the process begins all over again.
normally, the human body requires two pumps functioning at different pressures, high pressure to permits the blood to circulate around the body, and low pressure to give room/permits for optimal gas exchange in the lungs without broken capillaries.
