It would be A, because a fossil forms after an animal dies, and hundreds to thousands of years of soil or sediment coversit's body, preserving it. :)
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.

Answer;
-Simple squamous epithelium
Explanation;
-Simple squamous epithelium is the single layer of thin, flat cells that line body surfaces which are not exposed substantially abrasive forces. The primary function of the columnar cell is that secretion and absorption simple squamous epithelium a single layer flat scale shaped cells.
-Simple squamous epithelium lines the air sacs, or alveoli, of the lungs. The alveoli are sites where air is exchanged in the lungs. Simple squamous epithelial cells in the alveoli allow oxygen from the air to enter the blood in the capillaries of the lung.
Answer:
D. hotter rock rises and cooler rock sinks.
Explanation:
We know that as we move <u>towards Earth's center</u>, the <u>temperature rises</u>. This rise in temperature causes rocks to melt (magma). The high temperature and melting of rocks <u>decrease the density of material </u>which makes it <u>move upward</u>. By <u>moving upward</u>, the molten rock <u>starts turning solid</u> and becomes <u>denser again</u>. Here, it <u>sinks back due to gravity</u>. This upward and downward movement of rocks due to density and temperature makes a convection cell.
PS: The formation of convection cells in Earth's interior is also the reason for plate tectonics.
