A student wanted to know how the size of a moth mating chamber impacts the fertility of a female's eggs. The lab collected 400 egg masses from females living outside and allowed to mate naturally. The lab then set up 400 mating pairs in each shoebox sized, 16 oz, and 4 cup large plastic containers. After a week they collected egg clusters and counted how many clusters from each group hatched.
What is the control in this experiment and why?
The eggs outside because this is the unmanipulated, normal situation
The eggs in the shoebox sized mating chamber since the lab could buy many of these shoebox sized containers for cheap.
The 16 oz deli container since trial was expected to have the lowest fertility
The shoebox sized mating chamber because this is the un-manipulated, normal situation
A student wanted to know how the size of a moth mating chamber impacts the fertility of a female's eggs. The lab collected 400 egg masses from females living outside and allowed to mate naturally. The lab then set up 400 mating pairs in each shoebox sized, 16 oz, and 4 cup large plastic containers. After a week they collected egg clusters and counted how many clusters from each group hatched.
What is the independent variable in this experiment?
The sex of the moth
The 1600 egg masses
Number of fertile egg masses
Mating/egg laying environment

A lyre bird attracts mates by mimicking a combination of strange sounds in the forest (other birds' songs, the communication of monkeys, chainsaws, the click of a camera shutter). Generally, a more complicated song attracts a mate. Even when raised away from other lyre birds, the male will mimic the most complex combination of sounds to which he is exposed. However, the particular sounds vary based on what the male hears and mimics. The song of the lyre bird...
