<span>Because of the U shaped tube having a selective permeable membrane, the number of the water molecules on the sides changes but the number of the sugar molecules remain same. This particular cell membrane is such that it lets only specific kind of molecules and ions pass through.</span>
It is also called a decision lol!
Answer:
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
Answer: 40 mm Hg, 95 mm Hg, out of, down
Explanation:
In tissue cells the P(O2) is 40 mm Hg. The blood as it reaches the systemic capillaries around it has a P(O2) of 95 mm Hg. Hence, oxygen diffuses into the cells from the systemic capillaries down the partial pressure gradient. The carbon dioxide diffuses in the same direction at the same time.
Hence, the blanks will be filled with 40 mm Hg, 95 mm Hg, out of, down.
