In fruit flies, the gene for eye color is carried on the X chromosome. The allele for red eyes (R) is dominant over the allele for white eyes (r). A white-eyed male is crossed with a hom..zygous red-eyed female. The offspring of this cross were then mated with each other. Which distribution of genotypes is most likely in the F2 generation? A. 25% Xr/Y males, 25% XR/Y males, and 50% XRXr females

B. 25% Xr/Y males, 25% XR/Y males, 25% XRXR females, and 25% XrXR females

C. 50% Xr/Y males and 50% XrXR females

D. 50% Xr/Y males and 50% XRXR females

Please explain answer

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.
