Question

A scientist wanted to find out if the amount of plant food affects the number of beans produced in bean plants. Which of the following would be a good hypothesis for her experiment? A) since plants grown in poor soil often need food to grow is expected that bean plants given the most plant food will grow the tallest. B) since plants grown in poor soil often need food to grow is expected that the bean plants given the most water will produce the most beans. C) since plants grown in poor soil often need to need food to grow it is expected that bean plants given the most water will grow the tallest. D) since plants grown in poor soil often need food to grow it is expected that bean plants given the most plant food will produce the most beans.

Answer 1

Answer:

D) since plants grown in poor soil often need food to grow it is expected that bean plants given the most plant food will produce the most beans.

Explanation:

A hypothesis can be described as a tentative statement which can be proved to be either right or wrong through scientific experiments.

Since the scientists wanted to test the effect of amounts of plant food on the number of beans produced hence the most suitable hypothesis would be " since plants grown in poor soil often need food to grow it is expected that bean plants given the most plant food will produce the most beans."

Answer 2

Answer:

The correct option would be D) since plants grown in poor soil often need food to grow it is expected that bean plants given the most plant food will produce the most beans.

Explanation:

A hypothesis can be described as a tentative statement which can be proved to be either right or wrong through scientific experiments.

Since the scientists wanted to test the effect of amounts of plant food on the number of beans produced hence the most suitable hypothesis would be " since plants grown in poor soil often need food to grow it is expected that bean plants given the most plant food will produce the most beans."

Other options like option A are not correct because option A refers to the eight of the plant whereas we want to observe the number of beans.
