1. Researchers plotted a distribution curve for leg length in a population of birds, with length from short to long on the x-axis. The curve shifts to the right after a disturbance. Which statement is correct about natural selection in this population of birds?

Question

Birds with long legs were selected for.

Birds with long legs and birds with short legs were selected for.

Birds with medium-length legs were selected for.

Birds with short legs were selected for.

2. In peppered moth populations, light and dark moths are selected for in different environments. Which type of selection is this, and what would a distribution curve for all peppered moths look like?(1 point)

disruptive selection; a tall, narrow peak in the center of the graph

stabilizing selection; a tall, narrow peak in the center of the graph

disruptive selection; two peaks at the extremes of the graph with a dip in the middle

stabilizing selection; two peaks at the extremes of the graph with a dip in the middle

3. Over generations, female reindeer in a Finnish population give birth to larger offspring. Which type of selection is occurring, and how would a distribution curve for this trait change over time?(1 point)

stabilizing selection; the curve would become shorter in the middle

directional selection; the curve would shift to the left

stabilizing selection; the curve would become taller in the middle

directional selection; the curve would shift to the right

4. In a population of mice, individuals with medium brown fur are less likely to be seen by predators than light brown and dark brown mice. What type of selection is this, and what would the distribution curve for the mouse population look like?(1 point)

disruptive; a tall, narrow peak in the center of the graph

stabilizing; a tall, narrow peak in the center of the graph

stabilizing; two peaks at either end of the graph with a dip in the middle

disruptive; two peaks at either end of the graph with a dip in the middle

5. Paleontologists observed changes in the sizes of black bears as their environment changed. During warmer periods between ice ages, most black bears were small. During ice ages, most black bears were large. Which type of selection is this, and how would a graph of the distribution curve of black bear size change as Earth moved out of an ice age?(1 point)

directional; the curve would shift to the right

stabilizing; the curve would become taller in the middle and shorter on each side

directional; the curve would shift to the left

disruptive; the curve would break into two peaks with a dip in the middle
