Answer:
Does not take up the stain.
Explanation:
Negative staining refers to the process wherein the unstained specimen is visualized under the darkly stained background.
One of the examples is capsule staining wherein the capsulated cells are stained with India ink or nigrosin dyes. The particles of these dyes stain the background blue-black but cannot enter the capsule.
Hence, the light-colored capsulated cells are visualized in the midst of the blue-black background.

<u>Answer:</u>
When cells are in an <u>isotonic</u> solution, they are maintaining homeostasis.
<u>Explanation:</u>
"Homeostasis" is the process to maintain a stable and relatively constant internal environment. In addition to temperature it is maintained for many other factors too. "Isotonic solution" comprised of two solutions having the similar osmotic pressure across a semipermeable membrane.
Such solution maintain homeostasis of a cell via diffusion process. As in such solution the overall concentration on both sides of the membrane remains equal. The cell membrane command the movement regrading entrance and exit of anything in cell, the membrane control water and ion transport because of its phospholipid bilayer structure.
