Select the statements that are true. Question 1 options: CO2 and O2 are water-soluble molecules that diffuse freely across cell
membranes. The differences in permeability between artificial lipid bilayers and cell membranes arise from variations in phospholipid content. Transporters are similar to channels, except that they are larger, allowing folded proteins as well as smaller organic molecules to pass through them. Cells expend energy in the form of ATP hydrolysis so as to maintain ion concentrations that differ from those found outside the cell.

Explanation:
CO2 and O2 are highly soluble molecules in water due to their polarizability and their ability to react with water molecules and form new compounds. CO2 is 30 times more soluble in water than oxygen, which also has a high solubility. This ability allows these two molecules to diffuse freely across cell membranes.
Cells promote hydrolysis, that is, the breakdown of ATP molecules when they need to expend energy for any metabolic process, especially when they need to maintain a balance between ion concentrations inside and outside the cell. This is because ATP is a highly energetic molecule and its breakdown promotes energy for the cell to use in its activities.
A Fossil Fuel is the highest b Nuclear goes down during 2005-2015 but solar is the lowest through it all but it seems to increase a little between 2005-2015 so I’m not sure which one but it’s between those two
