Well I'm not exactly certain where the teacher is going with this, but an often used example is red blood cells (RBCs) aka: erythrocytes.
RBCs are suspended in blood plasma as they flood through vessels around and around the body, so the osmolarity (amount of small particles that affect osmosis) must remain relatively constant. This is termed "isotonic", meaning the same amount of osmosis-influencing particles that are there inside the RBCs' cytosol, within their plasma membranes.
If the plasma osmolarity get too high, called hypertonic (as with extra salt particles) then water inside the RBCs will have an osmotic force driving it out of the cells' membranes, to flow where there are more salt particles. This will lead to cell shrinkage (called "crenation").
Counter to that, if the plasma osmolarity gets too low, as due to low plasma salt with excessive water intake (for example from the condition "water intoxication"), then the plasma will be hypotonic with respect to the intracellular cytosol concentration. This can result in water rushing into the RBCs' membranes via osmosis, causing the cells to swell from discs into spheres (balls), or even rupture and burst (a phenomenon called "hemolysis").
HOPE THOSE EXAMPLES HELP!!
Troposphere -----------------
Answer:
The nutrient cycle describes the use, movement, and recycling of nutrients in the environment. Valuable elements such as carbon, oxygen, hydrogen, phosphorus, and nitrogen are essential to life and must be recycled in order for organisms to exist.

Answer:
OD. Lithosphere
Explanation:
The lithosphere is a strong rigid layer of the crust and the uppermost part of the mantle
When individuals in a population are unevenly spaced throughout their habitat, their dispersion was most likely random dispersion.
Habitat in simple terms is the place where an organisms lives. An organism carries out all its life activities in that area. These activities include eating, living, mating and reproduction. An organism's habitat must contain all the essential resources for it to survive efficiently.
Random dispersion is the type where the organisms are distributed randomly without any fixed pattern. These are a little rare to see in nature. The example of random dispersion is the dispersal of seeds from wind, they can spread in any direction.
