Which substances pass through a leaf's stomata?

To add to water-- Carbon dioxide cannot pass through the protective waxy layer covering the leaf (cuticle), but it can enter the leaf through a stoma (plural: stomata), flanked by two guard cells. Likewise, oxygen produced during photosynthesis can only pass out of the leaf through the opened stomata. 

(So water, carbon dioxide, and oxygen)

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
