So the answer is 75cm?
a 3 kg baby is 0.40m long at birth. How
long is it by the time it has doubled its
mass? Calculate the mass of a 2.0m tall man

answer is unreasonable. (0.50m; 375kg)
A friend breeds giant racing Rhosgobel rabbits. She is seeking your advice on how to breed faster rabbits. As per your request, she compared the mid-parent and
mid-offspring running speeds. Look at the graph to the below, which of the following statements provides accurate information to your friend.

Midoffspring running speed (m/s)
O a. The slower rabbits will produce faster offspring than the faster rabbits in the current generation.
O b.If your friend selectively breeds her fastest rabbits, you expect the next generation to be significantly faster.
OC. The best way to increase running speed in the next generation would be to alter the environment, maybe increasing nutrient density of the food.
O d. There is a higher degree of heritability in other populations of Rhosgobel rabbits.
