How are diffusion and osmosis different? A. Osmosis is the movement of proteins. Diffusion is the movement of water. B. Osmosis
stepladder [879]
The answer is B, osmosis is the movement of water. Diffusion is the movement to chemicals and molecules.

Both osmosis and diffusion are movement of molecules from a region of higher concentration of the substance moving to lower concentration down the concentration gradient. However, osmosis is only for the movement of water molecules, while diffusion is for any type of substances including liquid or gas. So we can also say osmosis is a type of diffusion actually.

And also, both of these movement of molecules does not require extra energy, they all happen due to natural tendency.

kolezko [41]
It depends on the individual reaction to lactose. first, some individuals are considered lactose intolerant meaning they lack enzymes that break down lactose into glucose and galactose. hence, if they digest dairy products they can have severe symptoms that will affect their health. however individual who aren’t lactose intolerant benefit from digesting lactose containing products because it improves the individuals health by providing the body with sufficient amount of energy when lactose is broken down to glucose and galactose. Also, consuming Foods in the Dairy Group provide nutrients that are vital for health and maintenance of the body. over all, it all comes down to how an individual will react to such decisions when eliminating lactose. If this decision outweighs the disadvantages then I agree with it however if it doesn’t I completely disagree
