A) one human somatic cell
Explanation:
A human genome is a complete set of DNA in somatic cell and it contains 23 chromosome pairs (nuclear genome). Beside nuclear genome cell also have mitochondrial genome.

Human genomes include genes that are protein-coding but also noncoding DNA.
Answer:
Brain stroke (Cerebrovascular Accident)
Explanation:
The blood is supplied to anterior areas of brain by carotid arteries and to the posterior areas of brain by vertebral arteries. The dysfunction of brain after stroke depends upon the corresponding brain area associated with blocked artery. The middle cerebral artery (found in cerebrum portion of brain) is most commonly blocked in stroke.
Stroke occurs when brain cells are deprived of oxygen due to the lack of blood cell. There are several type of strokes. It may be caused by the blockage of blood vessels due to depositions of cholesterol in blood vessels. It hardened the walls of blood vessels and narrow them causing hindrance in the blood flow. If this clot remain at one place it is known as ischemic stroke and if it can convert to embolus and travel across the body it would cause the embolic stroke.
Haemorrhagic stroke is caused due to rupturing of one of the blood vessel and it is the most crucial form of stroke.
