Question

The human population's life expectancy has increased significantly but seems to have an upper limit. Which of the following might be described as an ecological consequence of passing that upper limit by regulating cell death? A. a decrease in the birth rate a decrease in the ratio of younger to older members of the population OB. OC. an increased need for gerontologists and other professionals to care for the elderly OD. an increase in the relative frequency of deaths from cancer an increase in the total population of humans on the planet

Answer 1

Step-by-step explanation:

It is possible that some of the following options could be described as ecological consequences of passing the upper limit for human life expectancy:

A. a decrease in the birth rate: If the population has a higher proportion of older individuals, this could lead to a decrease in the birth rate, as fewer people are of childbearing age.

C. an increased need for gerontologists and other professionals to care for the elderly: As the population ages, there may be an increased need for medical professionals and caregivers to support the elderly.

D. an increase in the relative frequency of deaths from cancer: As people live longer, they may be more likely to develop age-related diseases such as cancer, which could lead to an increase in the relative frequency of deaths from these causes.

It is important to note that these potential consequences are not necessarily inevitable or certain to occur, and there may be other factors at play that could influence the outcomes described above.
