Hi.
All answers except B are correct.
When living things exhale, we release carbon dioxide. Producers use photosynthesis to make food & oxygen - using carbon dioxide.

Answer:
Firstly they are too big to pass through the natural pores of the cell membrane the way water molecules do through aquaporins. Secondly, they would not pass through the hydrophobic layer of the cell membrane because the sodium ions are charged. This is because the hydrophobic layer does not interact positively with charged molecules/ions. Additionally, because sodium ions would be traveling up the concentration gradient into the cell, there is need for active transport. The channels proteins are able to harness energy from ATP to actively transport the sodium ions into the cell.
Explanation:
this is mainly because when water evaporates, it leaves behind minerals, and even pollutants and goes up as clean water
Answer:
Carbon is stored
Fossil fuel deposits and the Earth’s oceans are two places in which <u>carbon</u> is stored
Explanation:
This is because the organisms that lived millions of years ago in the sea died off and their remains were compressed at the bottom of the ocean from carbon, thus creating the fossil fuels that we have today. This process took thousands of years.
