By performing photosynthesis, plants create everything they need to build all biomolecules. Is this true? Why or why not? (1 point)
This is true because photosynthesis produces glucose, and plants only need
sugars, not amino acids or fatty acids.
This is not true because plants need to sequester nitrogen from the soil to
build amino acids.
This is true because photosynthesis produces glucose, which has carbon,
hydrogen and oxygen-the building blocks for all biomolecules.
This is not true because plants need to perform cellular respiration to break
down the glucose into carbon, hydrogen, and oxygen.

When does the circulatory system work with the respiratory system? a. during blood cell formation b. during cellular respiration c. during intestinal digestion d. during a viral infection

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
