- A red blood cell with an intracellular fluid (ICF) concentration of 280 mmol/L, is placed into an environment were the concentration of the extracellular fluid (ECF) is 305 mmol/L. As a result, water will move across the cell/plasma membrane. a) Name the process by which water moves b) Describe the overall direction of movement of the water. Answer choices: (i) From outside the cell to inside the cell (ii) From inside the cell to outside the cell, or (iii) Equally, into and out of the cell iii Explain your reasoning for your answer to part (c). 1In your answer you must describe the environment on both sides of the membrane, and use 3 of the following 4 terms correctly; hypertonic, hypotonic, lower solute concentration, higher solute concentrationn (2pts -Correct use of biological terminology, and correct spelling is essential.

It is important to clean them daily using a sterile, isotonic cleaning solution. The concentration of solutes in the cleaning solution is the same as the concentration of the hydrogel in the contact lens. What would happen if instead of an isotonic cleaning solution, soft contact lenses are cleaned with water? (A) The soft contact lenses will shrink because it will remove too much water by osmosis. B The soft contact lenses will shrink because too much water is absorbed by osmosis. The soft contact lenses will swell and change shape because too much water is absorbed by osmosis. The soft contact lenses will swell and change shape because too much water is removed by osmosis.arrow_forwardOsmosis Define osmosis and why does blood cell become clear in distilled water?arrow_forward

- You fill a bag made of semipermeable membrane with a .5 mol/litre solution of sugar, seal it and immerse it into a .3mol/litre solution of salt and water. Which description best fits what will happen. 1) The environment is hypertonic to the contents, so the bag will shrink as water leaves the bag. 2)The environment is hypotonic to the contents, so the bag will expand as water enters the bag. 3) The environment is hypertonic to the contents, so the bag will expand as water enters the bag. 4) The environment is hypotonic to the contents, so the bag will shrink as water leaves the bag.arrow_forwardFor the following scenarios, determine whether the molecules in the scenario are moving by simple diffusion (S), osmosis (0), facilitated diffusion (F), or active transport (A). a)For water to travel across the cell membrane at a substantial rate, the water molecules travel through protein channels known as aquaporins b)While water molecules are polar, they are also very small. Some water molecules are able to squeeze directly through the phospholipid bilayer due to their small size. C)Charged ions such as Na* travel through a cell membrane against their concentration gradient d)Cells lining the gut need to take in glucose, but at certain times, the concentration of extraceliular glucose is lower than the concentration already stored in the cells. e)At a certain time, glucose is in a high concentration outside of a cell and needs to travel through the membrane into the cell but does so using a glucose transporter protein.arrow_forwardKnowing that there is constant turnover of phospholipids in a cell’s membrane and that new phospholipids are regularly synthesized, what strategy could a cell (or organism) use to maintain membrane fluidity and integrity in: A) Cold temperatures?
