Question

In any population there will be variations of certain characteristics. For example, in the giraffe population there is a variation in neck lengths among individuals. Some have longer necks and some have shorter necks. Which of these events would the giraffes with the longer necks have the best chance of surviving?
A) loggers come in a chop down all of the trees
B) insects can only eat the highest leaves due to the canopy
C) a plant disease infects the trees, resulting in total leaf death.
D) monkeys swarm in and tear off all of the lower leaves to use for shelters

Answer 1

Hi there!

The best possible scenario for the giraffes with longer necks to survive would be one in which all the lower leaves somehow disappear! This would mean only giraffes with longer necks can eat therefore those will have a better chance of surviving. Luckily the answer that fits that perfectly would be...

D. Monkeys swarm in and tear off all of the lower leaves to use for shelters.

Answer 2

D. Monkeys swarm in and tear off all of the lower leaves to use for shelters.
