Red blood cells are placed into a solution of unknown solute concentration. after an hour they have all burst open. the best explanation is that the solution 1. had a very high concentration of solutes. 2. was at equilibrium. 3. had a very high concentration of solvent had no solutes.

Option C

Explanation:

Red blood cells when places in a solution having higher concentration of solutes then the cells bursts.

The red blood cells when kept in the such of a solution bursts because of the hypotonic solution outside the cell.

The cells when kept inside hypotonic solution the solution will move from outside to inside of the cell and the cell will burst.

type 2 happens when excess consumption of high-sugar foods flood the blood supply with glucose and reduce the production and effectiveness of insulin. if a person has prediabetes, they can reduce the risk of full diabetes through regular exercise and a balanced, low-sugar diet.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
