<span>Large amounts of water can freely move across the cell membrane through aquaporins they are integral membrane proteins that serve as passageways in the movement of water, and in some cases, small particles can cross the membrane.</span>
Yes. All organisms go through cellular respiration. This is because cellular respiration requires oxygen. Very few organisms can perform respiration without oxygen.

The answer is <span>B. The carbon dioxide level in the city will be higher because the exhaust gases from vehicles release carbon dioxide and there are not many trees to utilize it.
It is known that in photosynthesis, plants use carbon dioxide and convert it into organic compounds. So, in a garden, there will be a lower amount of carbon dioxide than in a city. In the city, vehicles will release it in the atmosphere and if there are not many trees to utilize it, the carbon dioxide level in the city will be higher than in the garden.</span>
Radiometric dating is a kind of technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.
