Answer:
C. pH and temperature
Explanation:
Enzyme activity can be affected by a variety of factors such as temperature and pH
Answer:
B
Explanation:
More substances dissolve in water than in any other chemical. this is because of the polarity of its molecules. H²0 has a small positive electronic charge and the oxygen side has a small negative charge. the negative and positive charges help water dissociate ionic compounds into them.
Answer:
Diffusion, osmosis and active transport are three similar chemical methods by which single molecules or very small structures are moved across membranes or relatively short distances, often within or between cells.
Explanation:
The movement of substances in and out of cells is a very important part of biology as without it no cell and so no organism could live very long. Substances can only cross the protective cell membrane by diffusion, osmosis or active transport. Mass flow only works at the organ, tissue and whole organism level.
