Babies with very low or very high birth weight are less likely to survive. observe a graph of the data. a graph entitled percentage of babies born at different weights has weight in pounds on the horizontal axis, and percentage on the vertical axis. a small percentage of babies are born at the low and higher birth weights, and a greater amount are around 7 to 8 pounds. which statement is a valid claim that could be made using the data in the graph? directional selection is occurring because the graph favors an extreme. stabilizing selection is occurring because the average is favored. disruptive selection is occurring because the two extremes are favored. biodiversity selection is occurring because of the greater variation.

The pattern of this wave changes between its beginning and end. what is true about the amplitude and wavelength of the wave when the pattern changes?

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.
