It is true.
<h3>What is isotonic medium?</h3>
- A solution that has the same amount of salt as cells and blood. In hospitalized patients, isotonic solutions are routinely utilized as intravenous fluids.
- When a cell is immersed in an isotonic solution, there is no net movement of water into or out of the cell, and the volume of the cell remains constant.
- Isotonic solutions include 0.9% normal saline and lactated ringers. A hypertonic solution is one that has a greater solute concentration than the solution across the semi-permeable barrier.
- The isotonic solution allows the cells to move water and nutrients in and out of the cells. This is necessary for the blood cells to perform their function of supplying oxygen and other nutrients to other parts of the body.

Answer:
RNA molecules are made of nucleotides. (Ans. C)
Explanation:
RNA, which is also known as ribonucleic acid is found in cytoplasm of the cell, and synthesized in the nucleus. It is shorter, and a single stranded molecule. It is composed of one or more nucleotides which are linked together by phosphodiester bonds.
In RNA, the ribonucleotide contains pentose sugar ribose, four nitrogenous bases (A,U,C,G), and a phosphate group. RNA plays many types of role in cells, but mainly involved in the translation process, and it's regulation which is known as protein synthesis.
An enzyme lowers the activation energy of a reaction so it can take place within living organism, so an enzyme is a biological catalyst.
