anna is preparing 30 day of dessert for her pet beetle. she starts by mixing 3.67 grams of pureed ants with a 1.43 gram blueberry. she then divides the mixture into 30 equal parts one for each day. the international federation of beetle keepers recommends that a beetle should have 0.15 grams of such dessert each day. over the course of a seven day week, how many more grams of dessert will anna's beetle have eaten than the recommended amount?

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.
