PLS HELP ASAP What causes a tornado to form? Water vapor condenses, giving off energy. Wind over ocean water forces water vapor upward. A warm, moist air mass collides with a cold, dry air mass. Air pressure changes suddenly, causing rapid air movement.

What feature of cell theory is best demonstrated in the image

What evidence supports the law of conservation of energy? a) mechanical energy is converted to chemical energy during photosynthesis. b) oxygen is made from the breakdown of carbon dioxide during photosynthesis. c)energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis. d)the sun gives off light energy that is absorbed by plants.

Molecules like glucose and amino acids are not lipid soluble, so cannot cross the cell membrane by simple diffusion. instead, they are shuttled across by carrier proteins in the membrane from high to low concentration. does this process require energy from the cell? this is an example of what type of molecular movement?
