It takes seven seconds for the pupil to adapt once again to dark conditions after getting exposed to headlight glare.
The pupil of the eye refers to the black circle at the midpoint of the iris. The pupil functions mainly to monitor the amount of light getting inside the eyes, to make sure that to much light does not blanch out the visions in extremely bright light conditions, and to capture as much light as possible in dim light conditions.

Carbohydrate consists as the name as of carbon and hydrogen and oxygen in the same ratio as water (hydra). Another name for carbohydrates would be saccharides... this is for an example glucose, ribose and so on... and we use fx glucose in cellular respriation.
A carbohydrate<span> is a biological </span>molecule<span> consisting of carbon, hydrogen, and oxygen </span>
Cation-exchange chromatography is used when the molecule of interest is positively charged, the stationary phase is negatively charged and positively charged molecules are loaded to be attracted to it. So, the amino acids with negative charge will elute the first. Glutamate, leucin, arginine is the order of elution because of their pI values ~3, ~6 ~10.
The answer is C. These structures are vacuoles and are found in plants cell (you can tell it’s a plant cell because of the outer cell wall in the picture). Vacuoles have a variety of other functions storage of waste products, maintain turgor pressure for plants support.
