Two researchers are studying the decline of orangutan populations. in one study, a population of 784 orangutans is expected to decrease at a rate of 25 orangutans per year. in a second study, the population of a group of 817 orangutans is expected to decrease at a rate of 36 per year. after how many years will the two populations be the same?
the two populations will be the same after
years

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
