Part D) Think about pushing two boxes of different weights across the floor-one box is a lot heavier than the other box. How will the amount of force change as you push each box? Explain how this relates to energy expenditure of two people-one person who's heavler than the other.

This is on plato and edmentrum. :)

More force is needed to push the heavier box. Likewise, people who weigh more use more energy to move their bodies than people who weigh less.

answer; i believe the correct answer is (anemia);

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
