Answer:
BCIP/NBT
Explanation:
BCIP/NBT is a colorogenic substrate used for AP. AP stands for alkaline phosphatase. When they are catalyzed with this alkaline, we would have a product that has a dark blue or probably a purple color. NBT stands for nitro blue tetrazolium. Both of these work as substrate for the reaction. BCIP oxidizes BCIP to form this color.
Answer:
Active transport
Explanation:
Diffusion is when particles (like perfume) spread out everywhere from an area where there is a lot of it to where there is a little to none of it. Active transport is the opposite. A cell for example would use it's own energy to absorb nutrients when it already has quite a lot. Naturally diffusion would make the particles or nutrients go out of the cell because there is a lot of it inside the cell not outside, so active transport is used to absorb as much as the cell can from around it, even when it is full.
