_________ 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").

In humans, what gamete determined the sex of an offspring?
kari74 [83]

In humans, the "male gamete determines the sex of an offspring because it may contribute either an X or a Y chromosome"

<u>Answer:</u> Option C

<u>Explanation:</u>

Human sex gets decided by the function of SRY gene which possessed by with or without of Y chromosome. The hormone of anti-mullerian and testosterone produced from cells when activating the SRY gene. It generally confirms the development of single-male reproductive systems.

The scenario in humans, the sex ration gets affected by the male parent's hormone level. Also, in XY sex evaluation system, the sperm of male takes part in X or Y chromosome whereas the ovum from female contributes to X chromosome. This greatly results in offspring - either male (XX) or female (XY).

Less reproductive isolation among populations that share similar habitats

<h3>What is Reproductive Isolation?</h3>

The reproductive isolation mechanisms are a set of evolutionary mechanisms, behavioral, and physiological processes that are essential for speciation.

They either prohibit individuals of other species from having children or guarantee that any children are infertile. When individuals or groups diverge in the time of various behaviors, such as foraging or mating, reproductive isolation can arise.

Toad species Bufo americanus and Bufo fowleri exhibit reproductive isolation due to changes in mating season. Members of these species can successfully cross in the lab, resulting in healthy, viable hybrids. Temporal isolation, ecological isolation, behavioral isolation, and mechanical isolation are the three modes.
