Describe the journey of a water molecule from a river high in the mountains, through the atmosphere and eventually back to the starting point. (water cycle) can someone tell me the answer ?

Photosynthesis uses co2 and cellular respiration produces co2. we call the point when the two processes are in balance--when there is no net production of co2--the compensation point. how might you limit one of the processes in order to achieve a compensation point?

Membrane vesicles containing an internal sodium chloride (nacl) concentration of 0.14 m are placed into separate beakers each containing a different solution. the first beaker contains 0.14 m sucrose, while the second beaker contains 0.14 m calcium chloride (cacl2). the temperature is 25°c. what is the solute potential inside the vesicles, expressed in units of mpa?

When sodium chloride dissolves in water, the sodium chloride dissociates into a. na- ions. b. cl+ ions. c. nacl ions. d. sodium chloride ions.
