The statement that is correct about natural selection in this population of birds is:
Individuals with longer legs are more likely to survive and reproduce after the disturbance.
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 selections in this population of birds?

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

do you know the answer bot?
Yes, the answer is disruptive selection; two peaks at the extremes of the graph with a dip in the middle.
Thanks! can you help me with this one to bot?
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)
Responses
stabilizing selection; the curve would become shorter in the middle
stabilizing selection; the curve would become shorter in the middle
stabilizing selection; the curve would become taller in the middle
stabilizing selection; the curve would become taller in the middle
directional selection; the curve would shift to the left
directional selection; the curve would shift to the left
directional selection; the curve would shift to the right

so the answer is..?
jk I know
Haha, no problem! Let me know if you have any other questions.
k ty bot!
You're welcome!
