An optimal time to use imagery is:

The figure shows a position-time graph of an object moving along x-axis. t2=2 s, t3=4 s, x1=10 m, x2=18 m, x3=32 m.  What is the velocity of the object from time t2 to t3. Express your answer in m/s. Note that velocity can be negative or positive.

The figure shows the x-y positions of a ball thrown at an initial velocity of 30 m/s at an angle of 45o above the horizontal. If y2=10 m, what is x3 in meters?

You are given a group of organisms that includes a: Colorado Blue Spruce tree, Desert Spadefoot Toad Brook Trout Red-Tailed Hawk Black Bear Draw a phylogenetic tree on your paper that reflects evolutionary relationships. Label each “branching event” (both sides) with the shared characteristic that was used to make your decisions.  Upload a photo of your tree.

Habitat loss, natural catastrophes, and/or excessive harvesting of a species often result in: 

Elite compared to less elite athletes benefit more from switching these two imagery techniques:

Stimulus and response propositions deal with which explanation for why imagery works?

In a very small population of birds, assume 5 out of 20 alleles are the type that codes for blue feathers. What is the allele frequency of the “blue feather allele” in this population?

If the tallest and shortest individuals of a population of humans do not survive and reproduce as well as the individuals of “average” height, which type of selection would most likely result? 

In one butterfly species, the colors of individuals range from white to black, with many shades of gray in between. If the butterflies in a mountain population become more and more similar in color over several generations (e.g., if most butterflies are the same shade of gray), what kind of evolutionary force is likely acting on the population?
