Answer:d)introns; exons

The choices can be found elsewhere and as follows:
<span>body mass index
basal metabolic rate
resting heart rate
resting caloric count
</span>
I believe the correct answer is the second option. The term that describes the <span>number of calories the body uses at rest would be basal metabolic rate. Hope this answers the question. Have a nice day.</span>
