Answer:
Explanation:
In the first option, the compound has 1 hydrogen atom and 3 Oxygen atoms. There are 3 times as many oxygen atoms as hydrogen atoms.
In the second option, the compound has 2 hydrogen atom and 4 Oxygen atoms. That is 2:4 = 1:2. Therefore, there are twice as many oxygen atoms as hydrogen atoms.
In the third option, the compound has 2 hydrogen atoms and 1 Oxygen atom. There are ½ times as many oxygen atoms as hydrogen atoms.
In the fourth option, the compound has 3 hydrogen atoms and 4 Oxygen atoms. 4 oxygen atoms to 3 hydrogen atoms.

Answer:
Friend (endotherm) will need to eat more calories than snake (ectoderm) to maintain constant body temperature.
To generate heat endotherms convert the food they eat into energy through the process called metabolism. Most of the food that the endotherms eat is converted into fuel to maintain a constant body temperature. Endotherms need to eat more food than ectoderms of the same size to maintain their constant body temperature.
