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!!
Answer: B
Explanation: The amount of salt in the inner circle is equal to the amount of salt in the outer circle.
Answer:
Explanation:
<em>Each trait of an organism is determined by discrete units called genes and individuals carry two alleles for each gene. (Mendel didn't actually discover genes though). Each gamete of an individual carries only one allele of each gene (this is Mendel's Law of Segregation).</em>
the center of the solar system is the sun
Non-living parts?
A would be the answer then
sunlight certainly isn’t alive
