Question

directions: select the correct answer from each drop - down menu. field mice are sexually - reproducing organisms. in a population of field mice, traits that promote survival and reproduction are drop - down over time. traits that do not promote survival and reproduction are likely to drop - down over time. chart with bars labeled \increases in frequency\, \decreases in frequency\ reset submit

Explanation:

For the first drop - down (traits that promote survival and reproduction): In a population, traits that help organisms survive and reproduce are more likely to be passed on, so their frequency increases over time. So the correct option is "increase in frequency".
For the second drop - down (traits that do not promote survival and reproduction): Traits that are not beneficial for survival and reproduction are less likely to be passed on, so their frequency decreases over time. So the correct option is "decrease in frequency".

Answer:

First drop - down: increase in frequency
Second drop - down: decrease in frequency
