if i knew it i could tell you lol haha
If a membrane-bound sac filled with large molecules of oil is suspended in a beaker of water, water will start to enter the sac. The sac will then swell.

A patato cube is placed in a beaker filled with hot salt water and another patato cube is placed in a beaker filled with cold salt water?
There are three types of transport for molecules across the cell membrane. 1 - Diffusion - Molecules move from an area of high concentration to an area of low concentration 2 - Osmosis - same idea as diffusion, but refers to the movement of WATER across a selectively permeable membrane. How can you change water concentration? Add a solute. If you have 2 250 ml beakers, connected and divided by a selectively permeable membrane, and one beaker contains a salt solution, the salt solution is "hypotonic" (hypo- less, tonic - water) to the water filled beaker. One will see a migration of water into the salt solution beaker. BOTH diffusion and osmosis rely on concentration gradients to perform their jobs. They always want "equilibrium" between both sides of the membrane. 3 - Active transport - Proteins embedded in the cell membrane move large molecules through the cell membrane or AGAINST the concentration gradient. The size one is obvious; If it's really big, it won't permeate the membrane. As for the concentration gradient, this means that it moves a molecule INTO the area with and already HIGHER concentration. If this happens with say... H+ molecules, it creates a potential difference - ie - Voltage across the membrane. Cellular respiration counts on this process to create ATP/Energy for the cell.
Porins are proteins that are located in the outer membrane a bacteria. They function to form a water-filled pore through the membrane. The porin channel allows the diffusion of small hydrophilic (water-loving) molecules through to the periplasm.

Nuclear membrane
place starch solution inside the partially permeable membrane and than partially submerge it a beaker filled with distilled water. after some time, take the tubing out and test the water inside the beaker for starch by adding iodine solution. if the tubing is permeable to starch, the starch would have diffused into the water in the beaker and test positive for starch and turn dark blue. if not, then the water in the beaker would test negative for starch and remain a yellowish brown solution.
No, distiled water will not conduct electricity.
I have seen beakers with filled capacities from 25 mL to 5 liters.
The vacuole is a fluid-filled membrane-surrounded cavity located inside a cell
A vacuole is a membrane-enclosed fluid filled sac found in the cells of ... enzymes in vacuoles break down large molecules sent there for disposal. ... the plant; to cell elongation and to the processing and storage of waste products.
