Choose the best scientific design to test the question "which soil type results in the highest yield of tomatoes: clay soil or
sandy soil? "
measure the growth of 10 tomato plants that are grown in clay soil, and compare it to the growth of 10 tomato plants that
are grown in sandy soil.
measure the growth of a tomato plant that is grown in clay soil, and compare it to the growth of a tomato plant that is
grown in sandy soil.
o count the number of tomatoes that are produced by a tomato plant that is grown in clay soil, and compare it to the number
of tomatoes that are produced by a tomato plant that is grown in sandy soil
o compare 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.

preservation because he preserves part of the land and preserves means save

5. the study of energy and its transformations thermodynamics     -thermodynamics

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
