Why has the amount of water not changed over millions of years?

precipitation is about equal to transpiration & evaporation

What is a benefit of renewable energy?

they are sustainable and get be used for many years to come

Which BEST describes natural selection?

organisms with good traits will survive and pass them on

archaea live in extremely harsh environments

Which trend appeared EARLIEST in hominid evolution?

the ability to walk upright on 2 legs

Why is producing a large number of offspring important for natural selection?

it helps to ensure that enough organisms will survive

Which environmental argument might be used to STOP installing wind turbines?

they are not sustainable and cannot be replaced
they are more expensive and more difficult to use
14
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
