the man above me had the same answer i just did it as well because it's the right answer i looked it up i hope he or i help you guys <3
Answer:
diagram is weird and unrealistic but B is the only reasonable answer.
Explanation:
B only makes sense - everything else is unreasonable. Proteins don't become enzymes since enzymes are already proteins, there are no proteins, carbohydrates, or glucose molecules in the image.
Things around us are usually made up of combinations of elements. These combinations are called molecules. Molecules make up combinations called compounds.
Water is an example. There are 2 oxygen atoms and 1 hydrogen atom (oxygen and hydrogen are elements). Together there molecules make up H2O (water) which is a compound.
I hope this makes sense! I'm happy to answer any other questions you might have :)
