Sugar is needed for scientists to grow plants
1) Atmospheric Carbon Dioxide.
Trees are an important part to this planet because they take the carbon dioxide out of the air and convert it to oxygen. When deforestation occurs, there are less trees to do this, resulting in more carbon dioxide in the air.

Answer:
The major structural difference between chromatin and chromosomes is that the latter are more organized and condensed.
Explanation:
Chromatin is genetic material packaged into a complex by special proteins (histones). That complex is in the form of uncoiled structures, so chromatin fibers are long and thin. Chromatin structure is permissive to DNA replication, transcription and recombination events.
On the other hand, chromosomes are highly condensed structures of genetic material that are formed just before the cell division.
<span>When a cell is in a dynamic equilibrium with its environment, this means that the salt/water concentration inside the cell is equal to the salt/water concentration outside the cell. It is called an equilibrium because no transport of molecules is needed since the concentrations are already the same.</span>
Answer:
Alveoli
Explain:
They are the workhorses of your respiratory system. You have about 480 million alveoli, located at the end of bronchial tubes. When you breathe in, the alveoli expand to take in oxygen. When you breathe out, the alveoli shrink to expel carbon dioxide.
