30. Distinguish the difference between passive transport and active transport; include two examples of each and a brief description of each example. You could make a chart or a Venn Diagram to show your answer. (5 pts) 31. Three cells each containing 98% water are soaked in different solutions. Cell #1 is soaked in a solution containing 100% water. Cell #2 is soaked in a solution containing 98% water. Cell #3 is soaked in a solution containing 80% water. Explain where water would move because of osmosis occurring within each cell. Use vocabulary words to describe each solution. (5 pts) Explain water movement: Cell #1 Cell #2 Cell #3

00:01 Hello students in question number 30 we have to tell the difference between passive transport and active transport so let's see the active transport the passive transport so the first difference is the active transport this is a process in which the molecules and ions they move from lower concentration to fire with the help of atp which is a form of energy and for the passive transport this is a process in which the molecules and ions they move from higher concentration to lower concentration and there is no need of atp now the example of active transport are sodium potassium pump an example of the passive transport is the exchange of nutrients in kidney.

02:06 So here both active and passive transport, they regulate the entry and exit of molecules and ions in the cell.

02:26 And these processes, they transport only specific compounds to process continuously through the membrane and only requires a carrier to pass through the membrane, the passive transport, it can be classified into different types which are simple diffusion, osmosis, and facilitated diffusion.

03:04 So this is the answer for question number one.

03:06 Now question 30.

03:08 Now question number 31, we have given the conditions of three cells.

03:13 So we have to explain where the water would move because of the osmosis occur within the each cell.

03:20 So let's discuss this question.

03:22 Let's first discuss what is? osmosis.

03:27 So osmosis, this is a process of diffusion of water molecules through the semi -permeable membrane in according with the concentration gradient of the water across the membrane.

04:07 So the three different type of osmotic solutions are first as isotonic solution.

04:21 This is when the concentration of salute is balanced with the concentration of the which is inside the cell.

04:40 In isotonic solution, the water, it moves between the solution, but the movement rate are same in both the directions.

04:58 And second is the hypotonic solution.

05:10 So the hypotonic solution, it means that the solute concentration, this is lower than the concentration, which is inside the cell...
