The answer is frozen gases
Answer:
1.Carbon is small and has four valence electrons; these factors combine into a unique structure that allows it to easily make a chain of carbon atoms. It creates covalent bonds — the strongest bonds between atoms. A covalent bond is one where atoms share electrons to form a bond.
2.But what makes carbon unique is that it can bond with other carbon atoms to create long carbon chains and rings. No other element is capable of forming molecules as large and complex as carbon based molecules (think about it—without carbon chains and rings, there could be no DNA!)
3.Because the carbon-carbon bond is stronger than the silicon-silicon bond, carbon compounds stay together in water while silicon compounds break apart. Besides this, another probable reason for the dominance of carbon-based molecules on Earth is the abundance of oxygen.

Answer:
Answer is the muscle cells.
Explanation:
This is because they are responsible for all the movement occurring in the body. And ,it has been observed that, most energy are consumed or used through the movement of the muscles.
Also, the muscles require more energy because they have more mitochondria than other cells that require less energy.
The answer is: 200kcal
Physical activities will cause the muscle to burn more calorie. A child that more physically active would need more calorie to supply the energy need of the muscle. Ryder participate in many physical activities most of the days of the week, so the physical activities would be around moderate to very active. The upper limit of calorie addition for moderately active child would be 200kcal.
