We know that the efficiency of the immune system declines with age.Predictions of survival rates have been made through
A) the rate of cell division.
B) variable rate theories.
C) measures of immune cell levels.
D) All of these

Question

Quizplus · Accepted Answer

Measures of immune cell levels have been found to be the best predictor of survival rates in older adults. This is because immune cell levels decrease with age, resulting in a weaker immune response and increased susceptibility to infections and diseases. The other options (A and B) may be factors that contribute to the decline in immune system efficiency but may not provide a direct measure of immune cell levels and their impact on survival rates.
