In peppered moths, color is controlled by a single pair of alleles. The allele for dark coloration (D) is dominant to the allele for light coloration (d). The initial moth population consists mostly of light-colored moths. Industrial pollution then discolors the bark of most trees in the environment to a much darker shade than normal. After several generations, only 25 percent of the remaining moths are light-colored. 1. If the population enters into and remains in Hardy Weinberg equilibrium at this point, what will the frequency of the light-colored allele be after three additional generations?

2. What is the frequency of the dark-colored allele after three additional generations?

3. If there are 400 moths in the population after the three additional generations, how many of them are expected to be heterozygous for coloration?

4. If there are 400 moths in the population after the three additional generations, how many of them are expected to be h. o.m. o.zygous dominant?

Sally and sue were investigating the topic of friction in science. they used a small car and a ramp as seen in the picture to test what they were learning. they knew that they slipped easily on waxed floors but not on carpet, so they decided to change the material on the surface of the ramp to see what happened. they planned to use glass, carpet, aluminum foil, and sandpaper and run the car down the ramp over each surface. what would be the best research question to guide the girls' experiment? a) does the amount of surface area affect the friction on the moving car? b) will the car travel fastest on the glass surface? c) how does the angle of the ramp affect the speed of the car? d)do rougher surfaces tend to create more friction than smooth surfaces?
