<span>I think you might be asking about the 3 different osmotic conditions a cell might find itself in. Isotonic is the normal cell environment where water moves in and out of the cell freely and equally in both directions. It is in osmotic equilibrium so to speak. The concentration of water and solutes is equal on both sides of the cello membrane. In a hypotonic solution the cell will gain water and swell up -...</span>
the one that is considered a chemcial mutagen is : Tobacco Chemical mutagen refer to the substance that affected the DNA of those who consume the substancce or their offspring. Studies showed that consuming tobacco has proven to created DNA deformations for the fetus if it consumed by pregnant women.
<span>The answer is green, yellow or brick-red. If simple sugars are present, the blue solution will turn green, yellow or brick-red when combined with the food sample and heated. </span>Benedict's solution<span> is used to test for simple sugars, such as glucose. It is a clear blue solution of sodium and copper salts. When heated with the food sample, the blue solution changes color to green, yellow, and brick-red, depending on the amount of sugar.</span>
The right answer is <span>Refractory period.
At the moment when the action potential is emitted, the fiber being depolarized, it is impossible to depolarize it again. It is, therefore, necessary to wait until the membrane potential returns to a value below the critical threshold in order to be able to excite it again. We are thus led to distinguish two periods that characterize its excitability.
An absolute refractory period: during which any stimulation, even supraliminal, is ineffective since the fiber is already depolarized.
A relative refractory period: during which a second action potential can be omitted provided that the depolarization produced by the excitation reaches the critical threshold, which implies that it is more important since the value of the resting potential has not been restored yet.</span>
The least important role of nutrition in wellness is learning to <span>eat a high fiber diet. The other choices is important because a person should know the right diet he or she can take up. Learning to eat a high fiber diet is to specific and it is least important because you can have the right nutrition with the use of other vitamins and minerals also.</span>
