Compare means to tell how they are alike, but these molecules don't have roles that are alike.

Contrast means to tell how they are different.

Here's what they do:

ATP is the energy source for cell processes. ATP is broken apart to release energy for the cell to use.

RNA is instrumental in making proteins for the cell. mRNA takes the instructions from the DNA to a ribosome; rRNA makes up a ribosome; tRNA brings the amino acids to the building site to build the protein.

ATP and RNA are not alike.

1. chloroplast and cell wall 2. nucleous 3.cell membrane 4. Cells create TISSUES, which create ORGANS of all sorts, which can form an organisms body. 5. organic compounds contains carbon(any compound containing C is organic). 6. Carbohydrates, Lipids, Proteins, Nucleic Acids 7. passive transport does not require energy. it is the moving of liquid or particles to another area that happens regularly. active transport is transport that requires the cell's energy. 8. It is a membrane in cells that only allows a certain number of things in. 9. Diffusion-a passive transport where molecules move from higher concentration to lower concentration. Osmosis-Diffusion through a selectively permeable membrane. Equilibrium-where all areas of molecules are equal in concentration. DONT LISTEN TO RRS HES WRONG MANY TIMES
