4
Why is producing a large number of offspring important for natural selection?
it gives offspring protection from predators
it helps to ensure that enough organisms will survive
it helps to reduce population sizes of other species
it minimizes genetic variation
5
Which BEST describes natural selection?
organisms have offspring that have different traits
organisms learn traits that help them meet their needs
good traits an organism learns in its life will be passed on
organisms with good traits will survive and pass them on
6

walking on 2 legs
increase in cranial size
7
In autumn, leaves fall from trees as they go into hibernation. What causes this?
a decrease of sunlight
a full moon
a decrease in temperature
high temperatures in summer
8
Which tissue brings water upward in a plant?
dermal tissue
cambium
ground tissue

9
Why has the amount of water not changed over millions of years?
precipitation does not require energy
evaporation has increased over time
water vapor condenses in the air
precipitation is about equal to transpiration & evaporation
