a colorimeter is an instrument used for chemical analysis by comparing a liquid’s color with standard colors. in an experiment, a scientist used two colorimeters and noted the readings. the first colorimeter showed consistent readings that were five points lower than the actual reading. the second colorimeter provided readings that were the same as the actual reading. which two statements are implications of these readings?

a) the first colorimeter is reliable but not valid.

b)the second colorimeter is valid and reliable.

c)both the colorimeters are reliable and valid.

d)the readings of the first colorimeter can be used without repeating the experiment.

e)the readings of the second colorimeter aren’t reliable and can’t be used for the experiment.

The first colorimeter (i'm guessing is standard) is less exact then the actual reading, and has a harder time pin-pointing. (it gives a number near the actual temperature, but it is not correct.)

The second colorimeter is exact, and should be 'trusted more in the future', because it gives an accurate reading of the current temperature.

these are the 2 conclusions i got from the top information given to me.

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.  

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes
