Explanation:

Question 7

Congestive heart failure occurs when the heart's pumping ability is impaired, leading to fluid and blood backing up into the lungs. Cardiomyopathy is a disease of the heart muscle, rheumatic heart disease is from rheumatic fever, and congenital heart disease is present at birth. So the correct option is the one with congestive heart failure.

Cancer originates from a single abnormal cell that undergoes uncontrolled growth. So the statement "Cancer develops from a single cell that goes awry" is true.

Stage 4 of NREM sleep is the deepest stage. Waking up from stage 4 (now often combined with stage 3 in some models as slow - wave sleep) leads to the most grogginess due to the deep state of sleep. Stage 1 is light sleep, stage 2 is a transition, and stage 3 (formerly part of deep sleep) - but in traditional models, stage 4 was the deepest. So the correct option is the one with stage 4.

Answer:

A. congestive heart failure (assuming the first option is A, as per typical multiple - choice formatting with the first option being A. If the original had different labels, adjust accordingly. But based on the order, the first option is the correct one for this question.)
