Four substances (A, B, C, and D) are mixed in a test tube during a chemical reaction. The concentrations of the four substances are measured at 0s and at 100s. Time (s) [A] (mM) [B] (mM) [C] (mM) [D] (mM)

0 1 5 3 5

100 2 5 1 2

Based on the data, which substance was a product of the chemical reaction?

A.

Substance A

B.

Substance B

C.

Substance C

D.

Substance D

B

Explanation:

On Pearson Connexus

In a chemical reaction, atoms are neither created nor destroyed, therefore the concentrations should be the same.

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.  

the answer is: metamorphic rocks often show the presence of fossils, also a
