Plant leaves are organs that are composed of multiple cell types, including palisade cells and guard cells. Palisade cells contain many chloroplasts and are the main sites of photosynthesis in a leaf. Guard cells are specialized epidermal cells that can change shape in order to control gas exchange between the leaf and its surroundings.

Select all the correct answers. which statements fail to meet the requirements of a scientific claim? 1 even though evidence indicates that the solar system's planets follow elliptical paths, copernicus's model involving circular orbits is true. 2 the evidence supporting newton's laws of motion was accurate in newton's time, but the universe operates differently today. 3 flowers that reflect the most ultraviolet light are more likely to attract bees and other pollinators than flowers that reflect less ultraviolet light. 4 in the final 100 meters of a 10,000-meter race, an athlete's speed is more strongly related to anaerobic efficiency than to aerobic efficiency.
