Chapter 10, Problem 3DAA
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.
There was no correlation between early death of a male child and eating habits of his paternal grandmother, but there was a strong correlation with the eating habits of his paternal grandfather. What does this tell you about the location of epigenetic changes that gave rise to these data?

- The 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.

- Mortality due to lung cancer was followed ingroups of males in the United Kingdom for 50 years. FigureQ20–1 shows the cumulative risk of dying from lung can-cer as a function of age and smoking habits for four groupsof males: those who never smoked, those who stopped atage 30, those who stopped at age 50, and those who contin-ued to smoke.
