Mortality refers to
a. the number of cases of disease per unit of population occurring over a unit of time.
b. the first occurrence of menstruation.
c. the number of deaths attributable to a particular cause per unit of population over a unit of time.
d. the statistical likelihood of a person dying from a particular cause.
Studies indicate that humans were physically active in our evolutionary past.
True
False
When people think about living to an age far outside of normal expectations – say to 120 or even 150 years of age – they tend to think about their own lives and what they would do with such time. Extending the human lifespan to such lengths, however, might have drastic implications for public policy and the planet as a whole. Do you think that such an increased lifespan would be good for the population? Why or why not? Be thorough in your discussion of these factors.

- Mortality due to lung cancer was followed in groups of males in the UnitedKingdom for 50 years. Figure 20–3 shows the cumulative risk of dying from lung cancer as a function of age and smoking habits for four groups of males: those who never smoked, those who stopped at age 30, those who stopped at age 50, and those who continued to smoke. These data show clearly that individuals can substantially reduce their cumulative risk of dying from lung cancer by stopping smoking.

Some argue that the prevalence of screen time and social media are reasons for decline in physical activity and rise in obesity and other health problems. Others argue that these are unfair attributions for a population that has limited opportunities to participate in programs that have been eliminated or downsized or require a "pay to play" agreement. Are those proponents for countering the obesity epidemic through reductions in screen time, video games, and technology justified in claiming that these aspects are primarily responsible for youth physical inactivity and obesity? What would be a good thesis statement for the above scenario? (Thesis is a point of view that must be clear and unambiguously).arrow_forwardWhich of the following accurately describes a trophic cascade? a.

- Why is the world population increasing? Select one: a. Women in developing countries are continuing to have more children, thereby increasing the global fertility rate. b. Advances in medical technology are allowing the world population to live longer and decrease infant mortality. c. The global birth rate is continuing to surpass the death rate. d. A significant portion of the global population is getting older and retiring earlier.arrow_forwardIf the one- year cumulative incidence for exposed subjects is identical to that of non-exposed subjects then: a. one - years incidence rates must be identical for exposed and non- exposed subjects; b. survival curves must be identical for exposed and non- exposed subjects; c. median time to event must be identical for exposed and non- exposed subjects; d. none of the abovearrow_forwardLook at the question here, ____ Suppose a study looking at the association between smoking and bladder cancer found an odds ratio = 2.4. What would be the best way to interpret this? (Select one answer.) Smokers are 140% times as likely to develop bladder cancer compared to non-smokers. People with bladder cancer are about 40% more likely to be smokers compared to people who don't have bladder cancer. Smokers have a 2.4 % more risk of bladder cancer compared to nonsmokers. Smokers have 2.4 times the risk of developing bladder cancer compared to non-smokers..?arrow_forward
