A researcher is trying to design an experiment to measure the amount of energy a person uses during different activities. He pro
Tomtit [17]

The right answer is to measure the amount of released carbon dioxide.

The carbon dioxide exhaled by the lungs can reflect the energy consumed by the body since it comes from the degradation of glucose which is the main energy substrate. And this is a better indicator of energy consumption than measuring heart rate because it can be inflected by several factors.


A is false because glucose is not found in the urine, except in the case of diabetes mellitus.

C is false because the consumption of calories does not mean that we will directly use it.

D is wrong because perspiration is independent of energy consumption, this is a way to cool the body after exercise.

Lesechka [4]

Let 'C' denote the dominant trait of eye-crossing and 'c' denote the recessive trait of not being able to cross the eyes. The genotype of the father is heterozygous dominant for the trait of eye-crossing. This is denoted by 'Cc'. The mother is homozygous recessive for the trait of eye-crossing, denoted by 'cc'. The mating between the two will result in following genotypes: two of 'Cc' and two of 'cc'. Therefore the probability that the child will be able to cross his or her eyes is 0.5 or 50%.

75% purp, 25% white i would think. you could easily eliminate the 50% purp 50% white because that wouldn’t make sense, purp is the dominate color. it would most likely not be 100% purple because there are two 25-75 answers, which would most likely make it one of those answers. since purp is the dominate color, 75% white would not make sense, making the correct answer 75% purp and 25% white.
