A cell is incubated with a radioactive lipid called [3H]-palmitic acid. Membrane proteins are then isolated from the cell using multiple different treatments. High pH and high salt treatments serve to reduce the strength of ionic and hydrogen-bonding interactions. Determine the type of membrane protein that is isolated from each of these treatments.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

satellites are frequently used to make observations of the orbit on earth

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
