The best answer would be letter D. C<span>ompare the average number of tomatoes that are produced by 10 tomato plants that are grown in clay soil to the average number of tomatoes that are produced by 10 tomato plants that are grown in sandy soil.
It would be best to grow more than one tomato plant in each soil to truly represent the tomato's growth in them. To average the number of tomatoes yielded by each soil sample would also allow a sample that is more representative of the tomato plants than merely comparing single tomato plants.

A, D, and not sure but maybe E
B. I think correct answer
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.
