Compare the influence of genetic inheritance to environmental factors on individual health.
Genetic inheritance provides predispositions to certain health conditions (e.g., muscular dystrophy is purely hereditary). Environmental factors such as diet, exercise, exposure to toxins, and lifestyle can trigger, modify, or prevent the expression of many genetic risks (e.g., type-2 diabetes or heart disease). Thus, both genetics and environment interact to shape individual health outcomes.

Explain why children are at a higher risk of suffering negative effects from environmental hazards than adults.
Children are at a higher risk of suffering negative effects from environmental hazards than adults, because children do not have fully developed immune systems. In addition, children have a higher exposure to environmental hazards, because they spend more time outside, on average, than adults. Children also take in more air per unit mass than adults, which means that they also take in more pollutants relative to their size.
Explain how scientific advancements have lessened the effects of hazardous events on society.
Scientists are able to detect and predict some hazardous events through scientific advancements. By detecting these events early, society can prepare for the events, thereby reducing the amount of damage to people and property caused by the hazardous event.
How have scientific advancements been both beneficial and disadvantageous to society?
Scientific advancements have benefited society in a number of ways. Improvements in communication and transportation have helped stimulate economic growth. Advancements in medical technology have led to an increase in the overall health of society through vaccinations, antibiotics, and other medical technologies. Some disadvantages of scientific advancements to society are the increase in carbon dioxide emissions, the increase of hazardous waste, increased urbanization, and an increase in resource use. Some of these disadvantages can be curbed through further scientific advancements that lead to a decrease in waste production and employ alternative energy sources.
