The options for this question are:
- Requires genetic variation
- Results in descent with modification
- Involves differential reproductive success
- All of the above
Answer:
<u><em>The correct option is d) All of the above</em></u>
Explanation:
The theory of natural selection explains that genetic variations occur in organisms of a species. Those organisms which are better adapted to live in an environment are able to survive and pass on their characteristics to their offsprings, hence descent with modification. Through this phenomenon, evolution takes place with the passage of time. Natural selection favours survival of the fittest. Hence, all of the above statements are true.
Explain that water moves down a water potential gradient, and the salt solution has a lower water potential than the vacuole so water leaves the vacuole through osmosis
In exam Q's key points are:
- Water potential gradient
- Higher water potential in vacuole
- Leaves through osmosis
