Buffers, such as sodium phosphate, protects solutions and cells from undergoing drastic pH changes
Ozone layer is important. It protects us from UV rays.
A SolutionA Solutiona solution However: Mastering Biology by Pearson says that the answer is a BUFFER. Do NOT select "solution," as that is incorrect.
You can tell that plant cells are undergoing osmosis if they swell or shrink. When plant cells are placed in a hypertonic solution, they lose water and shrink. Conversely, when they are placed in a hypotonic solution, they gain water and swell. These changes in cell size indicate that osmosis is occurring.
An indicator. It is a substance that changes color in response to a change in pH, making it a useful tool in chemistry to visually determine the acidity or basicity of a solution.
Yes. Liquid or solid changes to a gas physically.
The term for a substance that changes color according to the pH of the solution is an indicator. Indicators are commonly used in chemistry to visually determine the acidity or basicity of a solution based on color changes.
A natural acid/base indicator is a substance that changes color in response to the acidity or alkalinity of a solution. It functions by undergoing a color change based on the pH level of the solution it is placed in. This color change can help determine the pH of the solution, with different colors indicating different pH levels.
solution that changes it's strength with the passage of time.

A substance is permanently altered by undergoing a chemical reaction that changes its molecular structure, composition, or properties. This alteration is often irreversible and results in the formation of new substances with different characteristics than the original substance.
As thermal energy is added to a substance, its temperature increases, causing its molecules to move faster and vibrate more. This can lead to changes in state, such as melting or boiling, depending on the substance and the amount of thermal energy being added.
Ozone layer is important. It protects us from UV rays.
An example of a substance that changes color is litmus paper. Litmus paper is commonly used in chemistry as an indicator to determine the acidity or alkalinity of a solution, as it changes color in response to the pH level of the substance it is in contact with.
Physical changes can be undone, and the substance undergoing the change is still chemically the same thing. It is just in a different form.
