A boy holds a ball of clay above the floor. He drops the clay ball, and it speeds up as it falls to the floor. The clay ball flattens as it hits the floor and remains flat. When the clay ball hits the floor, the clay
and the floor get a little warmer. (Assume that no energy is transferred between the clay ball and the air
or between the floor and the air.)

C. The total amount of energy in the system stays the same because the decrease in energy due to the clay ball moving closer to the ground is equal to the increase in energy due to the clay ball and the floor getting warmer.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
