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.

Explanation:
Answer:
Index Fossils can be used to identify a specific time period.
Explanation:
I believe it is natural selection. Natural selection is when over a period of time, traits that are formed to help the organism survive, are passed to the next generation. For example, if there were two types of rabbits. One had black fur and the other was white. They both lived in the artic. The black furred rabbits are mostly eaten by predators because their black fur is easily seen against the ice and snow. Over a period of time, the black furred rabbit would die out. The next generation would mostly have white fur to help them survive.
