Round 1: Tossup 3

Variants in the progranulin gene are linked to differences in this quantity among African killifish. Hypersensitivity to contact inhibition may explain why this quantity is unusually large for naked mole rats, which illustrate that neither body size nor this quantity is correlated with cancer prevalence by Peto’s paradox. This (10[1])quantity is the maximum value of the x-axis on convex type I and concave type III curves. (10[1])Max Rubner proposed that this quantity increases (10[1])with slower metabolisms. (10[2])By an outmoded (10[1]-5[2])theory, (10[1])stable ecosystems (-5[1])select for large values (10[1]-5[1])of this quantity (-5[1])and high (-5[1])parental (-5[2])investment in K-strategists. (10[1])Caloric restriction increases this quantity, which exhibits a tradeoff with fecundity (-5[1])and rarely extends to a post-reproductive stage. For 10 points, what quantity is extremely long for bowhead whales (10[1])and giant (-5[2])tortoises? (10[1])■END■ (10[9]0[3])

ANSWER: lifespan [accept maximum lifespan; accept healthy life expectancy or life expectancy at birth or LEB; accept longevity or length of life or equivalents; accept lifetime; prompt on age or time] (There are type I, II, and III survivorship curves.)
