Effect of Paternal Grandmother's Food Supply on Infant Mortality Widely available historical data on periods of famine show that before the industrial revolution, a failed harvest in one autumn often led to severe food shortages the following winter. Retrospective studies have correlated infant mortality with the abundance or food during a grandparent's child hood. FIGURE 10.11 shows results from one or these studies.
FIGURE 10.11 Relative risk of early death of female child, correlated with the age at which her paternal grandmother experienced a winter with a food supply, that was scarce (blue) or abundant (red) during childhood. The dotted line represents no difference in risk of mortality. A value above the line means increased risk; one below the line indicates reduced risk.
Children have a period of show growth around age 9. What trend in this data can you see around that age?

- There is no way to regenerate nonrenewable resources. True Falsearrow_forwardThe pesticide DDT was widely used in the 1940s as a method of insect control. In the late 1950s the first DDT-resistant mosquitoes were discovered, and eventually DDT-resistant mosquitoes were found globally. When DDT is used now, the development of DDT resistance in mosquito populations occurs in months rather than years.Which of the following best explains the observations concerning DDT resistance in mosquitoes? * nd 2 school The proportion of DDT-resistant mosquitoes in a population remains constant due to the metabolic costs of DDT utilization DDT is a chemical signal that delays normal reproductive cycles in many mosquito populations. Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT. A population of 1.492 finches is introduced to a rainforest.
