No. Osmosis is the movement of a solvent through a membrane (semi-permeable) from a less concentrated solution to a more concentrated solution to the point where the two sides reach equilibrium. Isotonic solutions are solutions where the two sides of the membrane are already at equilibrium - so there is no movement of the solvent (like water) - so this is different from osmosis.
Answer: E.
Explanation: Decreasing greenhouse gasses is good. You could always use the process of elimination for this! All of these are harmful to the environment except the decreasing of greenhouse gasses!
Fatty acids are mostly composed of chains of carbon and hydrogen. Fatty acids without double bonds are "saturated" with hydrogen. When a fatty acid has one double bond, hydrogen is released therefore the fatty acid is "monounsaturated". When a fatty acid has two or more double bonds, then the fatty acid is "polyunsaturated". Unsaturated fatty acids are usually takes in the form of oils as they are liquid in room temperature (in contrast to saturated fatty acids which are solid in room temperature). Unsaturated fatty acids are usually found in plant based fats such as oils. Therefore the answer to this question is sunflower oil.
