Yes
No
What does it mean for an animal to adapt?
when an organism changes to suit its environment
when an organism dies due to a change in its habitat

Why is reproduction essential to life? Choose two.
So a species will not go extinct
So species will go extinct
for an organism to maintain a balance in population size
So we can eliminate certain species
Which parenting behavior does NOT increase the probability that offspring will survive?
producing milk to feed offspring
protecting the offspring from predators
keeping the offspring warm in cold environments
abandoning young before the eggs are hatched
Which of these is a courting behavior that can increase a male's probability of reproductive success?

fertilization
All of the following are advantages of asexual reproduction except ____________.
produce varied offspring
spread and colonize certain part of an area
Reproduce without a mate
produce a large number of offspring
Which of the following is a disadvantage of asexual reproduction?
All organisms have genetic variation
Parents produces identical off spring which is not suitable for survival in a changing environment
Finding a mate is not needed
It can produce a lot of offspring

individuals look different from one another
only one parent is needed to produce offspring
populations of the organism increase more rapidly
species can better survive environmental changes
