Plant cells and bacteria both have cell walls. Many antibiotics work by breaking down the proteins that make up the cell wall, so bacteria become vulnerable to the human body's immune system. A. Plant cells are less complex than bacterial cells, and their cell walls are made of enzymes which prevent the antibiotic from breaking down the plant cell walls.

B. Plant cells are prokaryotic, and their cell walls are made of lipids which prevent the antibiotics from breaking down the plant cell walls.

C. Plant cells are simple cells, and their cell walls are made of carbohydrates which prevent the antibiotics from breaking down the plant cell walls.

D. Plant cells are eukaryotic, and their cell walls are made of different proteins which prevent the antibiotics from breaking down the plant cell walls.

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.
