Biology Questions and Answers Already Passed What is the maximum magnification of a compound light microscope? 500x 1,000x 2,500x 5,000x 2,500x A new multicellular organism has been discovered, and scientists want to study the organism's cell structures, including organelles. Which microscope should they use? scanning electron microscope transmission electron microscope compound light microscope simple microscope transmission electron microscope Which microscope uses a probe to map atoms on the surface of a specimen? transmission electron microscope compound light microscope scanning electron microscope scanning tunneling microscope scanning tunneling microscope According to the endosymbiotic theory, which cellular process was involved in the evolution of mitochondria and chloroplasts? symbiosis phagocytosis endosymbiosis photosynthesis phagocytosis Which is a function of the cell membrane? performs photosynthesis controls what enters and leaves the cell protects the external structures of the cell provides energy to the cell controls what enters and leaves the cell Chlorophyll is found in plant leaves and absorbs light from the sun to enable plants to perform photosynthesis. Magnesium is an important component of chlorophyll. The concentration of magnesium ions is higher in the root-hair cells of plants than in the soil. Which mechanism of ion uptake would best enable a plant to produce a steady supply of chlorophyll? osmosis diffusion passive transport active transport active transport What is shown in the image? prokaryote eukaryote chloroplast mitochondrion prokaryote The endosymbiotic theory states that chloroplasts and mitochondria evolved as a result of a prokaryotic cell engulfing a bacterial cell. a eukaryotic cell engulfing a bacterial cell. a bacterial cell engulfing a prokaryotic cell. a bacterial cell engulfing a eukaryotic cell. a prokaryotic cell engulfing a bacterial cell. Which homeostatic process is characterized by the diffusion of water molecules? active transport osmosis passive transport dynamic equilibrium osmosis A patient is in need of hydration. Which type of solution are the patient's cells most likely in? hypotonic hypertonic isotonic osmotic hypertonic The data in the graph are the result of a paramecium being placed in a hypertonic salt solution. Based on the data in the graph, which would most likely happen if the paramecium were placed in distilled water? The contractions would increase. The contractions would decrease. The contractions would cease altogether. The contractions would establish dynamic equilibrium. The contractions would increase. 11 Which two microscopes generate three-dimensional images? scanning electron microscope and scanning tunneling microscope transmission electron microscope and scanning electron microscope scanning tunneling microscope and transmission electron microscope compound light microscope and scanning electron microscope scanning electron microscope and scanning tunneling microscope
