If the pancreas secretes too little insulin, it results in ________. if it secretes too much insulin, it results in ________.

Montano1993 [528]

1 - Diabetes is a possible answer. When to little insulin is secreted, not enough glucose is broken down, which might cause diabetes (high blood sugar levels).

2 - Hypoglicemia. When too much insulin is secreted, all glucose will be broken down, and there will be no glucose left fot the blood (low blood sugar levels.

_________ cells must be in osmotic equilibrium with their surrounding environments, because if they swell or shrink their membra

dlinn [17]

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").

A group of scientists are observing a new found cell. They want to classify it as either a prokaryotic cell or a eukaryotic cell

valkas [14]

The question can be solved by using the difference between eukaryotic and prokaryotic cell.
Prokaryotic cell does not have a well defined nucleus. The nuclear material lies naked in the cytoplasm. It is known as nucleoid. While, eukaryotic cell has a well defined nucleus with a nuclear membrane.
Prokaryotic cell has a single chromosome while eukaryotic cell has more than one chromosome.
Finally, prokaryotic cell do not have membrane-bound cell organelles while eukaryotic cell have membrane-bound cell organelles.

Hope you could get an idea from here.

How are sex cells different from other cells in the body?

Readme [11.4K]

Sex cells are haploid, therefore it has half the number of chromosomes (23) while other cells have 46
