A growth curve for a
population of crabs is
shown. What is happening
at Point A?
A
Population growth decreases as individual crabs get older
The population is stabilizing as it approaches carrying capacity
Destruction of habitat is causing a decline in the population of the
crabs
Intro. Of a new predator is causing a decline in population
growth of crabs
Meiotic cell division results in gametes
that produce sperm & egg cells by:

Increasing the daughter chromosome number by 50%
Increasing the daughter chromosome number by 75%
An ecosystem has a stable population of whitetailed deer. What is the most likely outcome if
a new species of deer that competed for the
same resources were introduced?

Which process most contributes to
genetic variation in a population?
Crossing over during meiosis
