Mrs. Brown bought a maple seedling from the plant store, which weighed 10 pounds. She planted it in a large planter with 50 pounds of soil. She added water every week for 200 weeks. At the end of 200 weeks, she weighed the plant and pot together. It weighed 260 pounds. How did the maple seedling gain so much weight?

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

i think its white blood cells

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
