Question

The histogram represents the proportions of newborn mammals falling into various birth weight categories. The line graph represents mortality.
From the information given, which of the following conclusions is correct?

• A. Birth weight is undergoing continuous variation
• B. Birth weights is an example of discontinuous variation
• C. Birth weight is genetically linked to mortality
• D. Birth weight and mortality are inversely proportional

Answer 1

The correct option is D Birth weight and mortality are inversely proportional

A baby's weight at birth is strongly associated with mortality risk during the first year. The lower the weight, the higher a baby's risk of infant mortality. Neonatal mortality increases inversely proportional to birth weight.

So, the correct answer is option D.
