A woman treated her home with a pesticide that kills spiders. The first application killed 78% of the spiders. Two months later

WARRIOR [948]

Natural selection. Only spiders that were more resistant to the pesticide lived through the first spraying of the pesticide, thus we're the only ones that could reproduce. This in turn made the offspring of the previous generation more resistant as well; thus making the pesticide less effective.

Why do birds have hallow bones?

kari74 [83]

The hollow part of a bird bone isn't wasted space. In some bones, the hollow cavities contain extensions of the air sacs from the lungs. These air sacs help the bird to get the oxygen it needs to fly quickly and easily.

Drawing a cartoon in pencil, then going back over it later with an ink pen is most similar to which biological process?

Montano1993 [528]

Given that the main reason for which an artist will retrace a drawing in pen is to correct errors and achieve a final draft, we can compare this to the biological process of DNA proofreading.

DNA proofreading is a biological process that takes place during the biosynthesis of DNA. During this time, a chain of DNA is read and a complementary chain is creating, effectively duplicating the genetic code.

During this process, DNA proofreading takes place. This is described as a process in which the DNA polymerase retraces the genetic code, detecting and fixing any errors in the synthesis before the strand is closed once again.

The fact is that both processes, despite taking place in astronomically different situations, share a final goal which is to prepare the "product" for the "final draft". This allows us to draw valid comparisons between the retracing of a cartoon and the proofreading of DNA by the DNA polymerase enzyme.
