-What is a hypertonic solution? & -What happens to a cell when it's in a hypertonic solution?

-A solution that has a higher concentration of solutes in comparison to the cell -The cell will SHRINK because water is going to move out of it

-What is a hypotonic solution? & -What happens to a cell when it's in a hypotonic solution?

-A solution that has a lower concentration of solutes in comparison to the cell -The cell will SWELL because water is going to move into it

Nitrogenous bases are located on both strands of the DNA double helix. What is the significance of the nitrogenous bases? A The number of adenines and cytosines determines the type of RNA that will be produced. B The order of nitrogenous bases determines the order of amino acids in the proteins synthesized. C The amount of thymine and guanine in the DNA molecules determines the length of the genes. D The type of hydrogen bonding between the nitrogenous bases determines which amino acid will be added to the peptide chain.
