What is the difference between osmosis and diffusion?

a. osmosis moves molecules, such as water, through a semipermeable membrane. diffusion moves molecules, such as oxygen and carbon dioxide, through a permeable membrane.

b. osmosis allows all molecules to move from areas of higher concentration to areas of lower concentration. diffusion allows only water molecules to move from areas of higher concentration to areas of lower concentration.

c. osmosis requires facilitation by a channel protein. diffusion requires additional energy from an energy-carrying molecule like atp.

d. osmosis occurs over an area called a concentration gradient. diffusion occurs over a membrane bilayer.

Are these strong bases, neutral, strong acids, weak acids or weak base household bleach (ph=12.6) fluid in a car's battery (ph of less than 1.0) milk (ph=6.7) stomach contents (ph=2.2) pure water (ph=7)

The seed coat's most important function is to provide a) a nonstressful environment for the megasporangium. b) the means for dispersal. c) dormancy. d) a nutrient supply for the embryo. e) desiccation resistance.

The graph below compares the rates of reaction of a burning candle and an exploding firework. comparing chemical reactions what can you conclude from the graph? the reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires less energy to start, and occurs less rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires more energy to start, and occurs less rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires more energy to start, and occurs more rapidly than the reaction that causes a candle to burn. mark this and return
