A scientist wrote a paper titled “Directional Selection in Action” after observing a population of mice for 15 years. The mice typically preferred to eat berries, although a few would also eat insects. After a drought in year 3, the scientist observed that more mice were eating insects. By year 10, most of the mice in the population ate insects in addition to berries. Which best describes her article?
Her title is accurate because two opposite extremes are favored.
Her title is accurate because one extreme is favored.
She should change her title because she is observing stabilizing selection.
She should change her title because she is observing disruptive selection.

Interpret the model. a three-part model with black right-arrows between the parts. left part: a large green apple-shaped component with a w-shaped indentation centered on top. a small blue apple-slice shape sits above the left indentation and an arrow points from the shape to the indentation. a small purple apple-slice shape and arrow sit above the right indentation and an arrow points from the shape to the indentation. middle part: a large green apple-shaped component with a square indentation centered on top. sitting in the left side of the indentation is a blue apple-slice shape with a flat bottom, fused to a purple apple-slice shape with a flat bottom on the right side of the indentation. right part: a large green apple-shaped component with a w-shaped indentation centered on top. an up-arrow is centered above the indentation pointing to a fused blue and purple apple-slice-shaped flat-bottom component sitting above the indentation. assigne "true" or "false" to the end of each statement. the model shows a shape change occurring in the enzyme after the substrate is bound in the active site. t/fthere are two products in this model. t? f there are three substrates in this model. t/f the model shows two different enzymes. t/f
