Btw science and biology are almost the same thing
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!!
Explanation:
Fear is a barrier as people fear being judged for things as there might be a stigma attached to it. When people are judged their problem isn't solved and instead worsened and they will feel compelled to keep their problems to themselves.
The Lysosome is the eukaryotic organelle responsible for cellular digestion. <span>Lysosomes hold enzymes that were created by a cell. They are known as "little digestion machines." A </span>Lysosome<span> is an organelle that breaks down other organelles that are no longer useful. Therefore, A would be the correct answer.</span>
Answer:
C the specific shapes of bacteria
Explanation:
It is responsible for sustaining a cell's shape, for the locomotion of a cell, and for the movement of the various organelles within the cell itself. Besides the intracellular movement of organelles, the cytoskeleton is responsible for chromosome movement during cell division and for cytokinesis.
