Question:
One of the team members suggests a test of the design using a bar magnet, as shown above. In her proposal, she explains the effect of changing the direction and position of magnets. Select the statement that correctly describes the effect of magnet direction and position on their relative potential energy.

Question 11:
Sunlight consists of multiple colors of light, as seen in Figure 1 above. Plants absorb sunlight in order to complete photosynthesis and produce glucose. The graph in Figure 2 above shows the percentage of different colors of light that are absorbed by green plants. Identify the model (Model A or Model B) that best represents the data. Explain your identification.

Scientists measured the spot size of all the guppies (small fish) that lived in a river 40 years ago. They measured the spot size of the guppy population again last year.

When was there more variation in the spot size of guppies in the river?

Tree squirrels can have different fur colors.
Squirrels live in forests where foxes also live. Foxes hunt squirrels for food. Squirrels that have fur the same color as the trees are harder for the foxes to see and catch.
The diagram above shows a population of squirrels that lived in a forest. Scientists had previously only seen brown and gray squirrels in this forest; they had never seen squirrels of any other color.
The diagram below shows how the population changed after many generations.
