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

a. her results provide evidence in support of her hypothesis

Explanation:

A hypothesis can be described as a predicted statement(s), which includes the information or explanation for a phenomena. It includes the facts or evidences that are required to be proved experimentally. If the result and conclusion of the experimental procedure proves the statement(s) of the hypothesis than it can be said that the hypothesis is true otherwise false.

According to the given situation, the results shows that the spiders which feed on caterpillars reach sexual maturity faster than those who feed on beetles. These results matches with the pre-proposed explanation of the hypothesis. Thus this can be said that the results are providing evidence for the hypothesis. Hence, it can be said that the hypothesis is true.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
