Ivana is studying insect life cycles. she placed a male and a female gnat inside a terrarium. the female gnat laid eggs, ivana
observed and recorded all of the stages she saw the eggs go through. her results are shown in the table below.
stage time in stage
egg 24 hours
larva 7 days
pupa 6 days
adult 2 weeks
which of the following is a valid conclusion that ivana can draw from her data?
a. agnat generally does not live for more than 1 week.
b. agnat completes its life cycle in about 1 month.
c. agnat life cycle has more than five stages.
d. agnat is a crustacean, not an insect.

B. A gnat completes its life cycle in about 1 month.

Explanation:

hope this helps. i know the question is hella old, but- yk

C. The finches all appeared to be related but different from the mainland population.

Darwin compared the finches of Galapagoes island and Mainland. He hypothesized the fact that one species might have migrated to the Galapagoes island from mainland and undergone with modifications in different ends from the ancestor species. He proposed that around 13 species of finches evolved from a single ancestor species. This process in which one species giving rise to multiple species which have different corresponding niches is called as adaptive radiation. These finches were adapted according to their different diets: seeds, flowers, insects and leaves. The ancestor finches were ground-dwelling and insect eating. The expense of speciation  in the Galapagoes island resulted in 14 species of finches which includes three species of ground-dwelling seed eaters, three others living on cactus and eating seeds, one living in trees and eating seeds, and 7 species of tree-dwelling insect-eaters. Therefore, the finches all appeared to be related but different from the mainland population.
