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 summarizing her results, the student reports that the spiders fed on caterpillars reach sexual maturity two weeks before spiders fed on beetles. in her conclusion, the student correctly states that a. her results provide evidence in support of her hypothesis b. her results are inconclusive c. her results provide support for her theory d. her results prove her hypothesis
