The question is incomplete, however, the statements associated with this question is given in the comments and here as well:
Neither facilitated diffusion nor osmosis requires cell energy.
Diffusion of gases and other small molecules requires no energy on the part of the cell.
Active transport requires cell energy and osmosis doesn't.
Both endocytosis and active transport require cell energy.
Answer:
The correct answer is - Active transport requires cell energy and osmosis doesn't.
Explanation:
Osmosis is an example of passive transport as it does not require energy to facilitate the movement of solvent In the process of osmosis,. It moves from high concentration to low concentration through the semipermeable membrane which is along the gradient so no requirement of energy.
In the case of Active transport, it requires energy to facilitate the movement of transport as it is the movement of a substance from low concentration to a high concentration area that is against the concentration gradient.
Answer:Physical systems differ from social systems because a physical system refers to systems that rely on a group of physical parts to perform a function. Examples of a physical systems are solar systems or even an animals digestive system. Social systems are systems like an ant colony, wolf pack, or a town.
Explanation:
- a living species
- adaptation
- Reproduction
- Change

The sodium hydroxide solution and vegetable oil underwent a chemical change.
<h3><u>Explanation:</u></h3>
The reaction between a base and a fat or fatty acid is called as saponification reaction. Here the base dissociates into the cation and hydroxyl ion. The hydrogen from the fatty acid of the oil reacts with the hydroxyl ion to form water which is basically the neutralization reaction. This cation now reacts with the rest of the fatty acid to form a bipolar molecule which is the soap. During the reaction, the solution becomes cloudy but with time, it again goes back to solution. The cloudyness appears because oil isn't soluble in water based solutions and the base is actually made solution in water.
Here the sodium hydroxide reacts with oil to form water and the soap molecule which is a chemical change.
