Mrs. Strunk's Earth Science class used an erosion model to investigate the relationship between the slope of a hill, or incline, and
the amount of soil that washes off of the incline.
The class increased the slope of the incline from 1 to 5. Then, they poured 100 ml of water down the incline. Finally, they
collected the soil from a tray at the bottom of the incline, dried the soil in an oven, and used a balance to find the mass of the soil.
The data from their study is shown below.

C.
the slope of the incline is steeper.
D.
there are fewer rocks in the soil.

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
