What is the main way that active transport differs from diffusion?

Active transport is different from diffusion because it requires energy expenditure, while diffusion requires no energy at all. In diffusion, materials are moving from areas of high concentration across the cell membrane into areas of low concentration. This requires no energy on the part of the cell. In active transport, however, the cell is moving material between two areas of equal concentration, or from an area of low concentration into an area of high concentration. This requires the cell to expend energy.

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
