When you stain a cell that reacts with an enzyme that is found in the lysosome, you would expect to see the dye in the endoplasmic reticulum. Cell staining is the name of this test. It is used to visualize the cell much better in a microscope. There are certain stains to be used depending on the need.
The third one, hope this helped.
Answer:
move molecules into or out of cells of the body
Explanation:
Majorly, there are two types of transport used by living cells. These are; passive and active transport. Passive transport involves the movement of molecules down a concentration gradient without the need for energy (ATP) input. Example is DIFFUSION AND OSMOSIS.
On the other hand, active transport is a type of transport that moves molecules against a concentration gradient (low to high) with the aid of energy input (ATP). Example is sodium-pottasium proton pump.
Although there are obvious differences between these two processes (diffusion and active transport), but they both MOVE MOLECULES INTO OR OUT OF CELLS OF THE BODY.
