The heart and the arteries of a person, both contracts to pump the blood throughout the body. The aorta, which is the largest artery of the human body, pumps the blood from the heart to the entire body of a person. The oxygen-rich blood is pumped out of the left ventricle when its contraction into the aorta, from where it is transported to the whole body.
Hence, the given statement is true.
Muscle cells, also known as myocytes, contain numerous amounts of mitochondria inside of their cytoplasm. Mitochondria are organelles that are popularly known as the powerhouse of the cell because they function to process different biochemicals (such as glucose, oxygen, etc) and produce essentially Adenosine Triphosphate (ATP). Kreb's Cycle in particular talks about energy production, and the mitochondria is one of the main units where this cycle happens. You can think of ATP as the currency of the body in terms of energy. The more ATP one has, the more energy there is available for use by the different systems of the body. Muscles in particular have high demand for ATP.

Answer:
C. Genetic material composed of nucleic acid
Explanation:
The information needed by every organism to perform life functions like reproduction, growth etc are held in the genetic material that the organism carries in its genome. Every genetic material of organisms is composed of nucleic acids, which are only two in nature i.e. Ribonucleic acid (RNA) and Deoxyribonucleic acid (DNA). This is a common feature of all organisms including bacteria and viruses that they contain genetic material which must be in form of a nucleic acid.
The viruses do not undergo a cell division, neither do they contain protein synthesis structures called Ribosomes because they do not have the ability to reproduce or perform any living process outside a living host cell. This means that they strictly depend on another organism's transcriptional, translational, replicational ability to survive.
