A roller coaster cart at the top of a hill is an example of ___________ potential energy.
Gravitational
100
Who would have more gravitational potential energy?
A 100 pound person on a hill or a 150 pound person on a mountain? Why?
A 150 pound person on a mountain. The more mass you have the more gravitational potential energy you have. The higher something is the more gravitational potential energy it has.

A species of fish living in a stream displays variation in body color. Fifty years ago, most of the fish were light-colored but a few were dark-colored. Over time, the clear water of the stream became cloudy and the population of dark-colored fish increased.
Why are more dark-colored fish found after the water became cloudy?
The light-colored fish reproduce less and are eaten more by predators because they are more easily seen. The dark colored fish reproduce more

In seals, the gene for the length of the whiskers has two alleles. The dominant allele (W) codes long whiskers & the recessive allele (w) codes for short whiskers.
Create a Punnett Square from the cross of two long-whiskered seals, one that is homozygous dominant (WW) and one that is heterozygous (Ww).
What percentage of the offspring will have short whiskers?
0%
