Passive transport moves molecules and ions from a higher concentration to a lower concentration without any energy while active transport does the same thing only it uses energy. Osmosis deals with the net movement of solvent molecules through a membrane with a higher solute concentration. Osmosis and active transport both work together, while osmosis does its own movement the active transport moves the dissolved solutes across a membrane against a concentration gradient.
Active transport and passive transport are almost the same they function the same only one doesn't require energy while the other one does. Hence why active transport and osmosis work well together it's because of the energy that helps transport dissolved solutes.
Osmosis is the diffusion of water across a membrane.
Active transport is the movement of molecules form an are of low concentration to and area of high concentration.
Passive transport is the movement of molecules form an area of big concentration to an area of low concentration.
Osmosis, Active transport and passive transport are similar in that they are about the process of moving molecules form one area to another. They are different in that they all move the molecules to different areas and osmosis is the movement of water molecules only where as the others may move the same molecule at times.
Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet's history. They can also help scientists reconstruct the evolutionary histories of present-day species.
I believe a possible option for this would be an antibiotic, many specialized kinds interfere with the growth and development of microbes including bacteria.
We do not gain the mass of the food we eat. Therefore, B is wrong. Our cells do not grow in size, they only grow in number. Therefore, C is wrong. Although the puppy's body does, in a way, stretch out, A is a better option. Therefore, D is likely to be wrong.
A catalyst increases the rate of reaction by providing a metabolic pathway that requires less energy. There for they work by decreasing the activation energy of a reaction.
