The categories  of energy expenditure include the following:
- Resting metabolic rate - This is the total number of calories burned when your body is completely at rest and accounts for 60-75 percent
- Thermic effect of feeding - This happens during feeding in which the metabolic rate increases and heat is produced and accounts for 5-15 percent
- The thermic effect of activity -  the amount of energy burned during all physical activity and accounts for 15-30 percent.
<h3>What is Energy expenditure?</h3>
These are the processes which involves how energy is used or spent. The categories are mentioned above with their appropriate explanations.

To solve this problem on genetic dominance, we will need a punnet square.
Let's let P represent purple-flowered and p represent white-flowered.
We have one purple flowered plant with the alleles PP, and we have one white flowered plant with the alleles pp. Using a punnet square, we can determine the alleles of the offspring.
       <u>P</u>     <u>P</u>
p|    Pp   Pp
p |   Pp   Pp
As we can tell from our punnet square, all of our offspring will have purple flowers. This is because the purple-flower allele is dominant and the white-flowered allele is recessive.
Since each flower has a dominant and recessive allele, they are heterozygous.
Therefore, the solution to this problem is D.
