Cellular respiration
Explanation:
The energy animals need for their life functions are released when their cells carry out cellular respiration.
Cellular respiration is a metabolic process by which living organisms breaks down organic molecules using oxygen especially glucose to produce energy and gives off carbon dioxide and water in the process.
It is the reverse of photosynthesis.
During this process, chemical energy stored in food substances are released and converted to heat energy.
The process takes place in the mitochondria of a cell.

<span>The elements that are found in a high proportion in Earth's crust are oxygen, aluminium, iron, calcium, potassium, sodium, and magnesium. But for your Option, I think it is B) Oxygen and Silicon. This is because Oxygen makes 46.6% while Silicon makes 27.7% of the Earth crust.</span>
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement
Answer:
Substitution Mutations
Explanation: A substitution mutation occurs when specific bases (A, T, C or G) in a gene are swapped for different ones. This type of mutation doesn't cause a difference in the number of bases like insertion or deletion mutations do. Substitution mutations just switch out one or more bases for different ones.
