Calculate the osmotic pressure at 25°C across a semipermeable membrane separating seawater (1.14 M total particles) from a 0.547 Msolution of aqueous NaCl.
What types of molecules can pass through a membrane without the aid of a membrane protein? What types of molecules use a membrane protein in order to cross the membrane?
When particles emitted by a radioactive source pass through a magnetic field, it is found some have bent trajectories, as shown in the figure. Ray 2 is not bent, while the other rays are bent; this observation indicates that The particles in ray 2 are uncharged, while the particles in rays 1 and 3 are charged The particles in ray 2 and 3 are uncharged, while the particles in ray 1 is uncharged The particles in ray 2 have a...
Describe the way the water would move through the semipermeable membrane. Explain what type of transport this is, how you know, and whether or not it requires energy. * Your answer
Please explain it with steps, Thank you! 5 A cell s a semipermeable membrane through which water may pass. If a cell, having a salinity (salt content) of 1.5% w/v NaCl, is placed in a solution made of normal physiological saline (0.9% w/vNaCl) which way will the water flow? Explain your answer. (Diagrams are OK also, but need to have words explaining it.) Flow of water Bag is a sem permeable Solution in bag "cell" Solution outside of bag (the...
Explain why H+ and Na+ ions cannot pass through lipid bilayer but they can pass through biological membrane.
Questions I a) What is osmosis? b) What is dialysis? Can MgSO4 pass through? Explain. 2. Can starch pass through a dialyzing membrane? (Support your claim with evidence from the experiment.) 3. Explain why people who are adrift in a lifeboat without a supply of fresh water are advised not to drink ocean water. note - Ocean water is saltier than body fluids like blood plasma. 4. In terms of osmosis, what happens when fresh water is inhaled into a...
