The answer is C
Explanation:
Answer
The correct order to describe the carbon cycle would be;
• The carrot plant takes in carbon dioxide from the air during photosynthesis(3)
• The rabbit eats the carrot plant(2)
• The rabbit decomposes(1)
• The carbon compounds are returned to the soil (4)
Explanation
Carbon is captured in the food web through autotrophs (carrot plant) which undergo the process of photosynthesis. The captured carbon will utilized in making organic compounds (glucose). Heterotrophs (the rabbit) will feed on the carrot to allow the organic carbon to proceed into the food chain. Decomposers (acting on dead rabbit) release organic compounds and carbon iv oxide during breaking down of the decomposing matter. Biologically carbon is returned to the environment and soil after this stage.
Answer:
CO2 and O2 are water-soluble molecules that diffuse freely across cell membranes.
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.
