How do most cancers arise? question 1 choices choice a., from a single mutations arising simultaneously in a cluster of cells choice b., from a series of mutations that arise in the descendants of a single somatic cell choice c., from multiple mutations arising simultaneously in a single cell choice d., from mutations arising in a single cell that are then transmitted to other cells in the body?

thinking it would be d not too sure but i think it's right

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
