Step 1
Which of the following is a suitable hypothesis to be tested by the students?
Answer
A suitable hypothesis must be testable and specific. Among the options provided:
- (A) is too general and lacks specificity regarding the type of plants.
- (B) is also not specific to a particular type or condition necessary for testing.
- (C) specifies Pea plants and compares the growth in red light against blue light, making it a clear, testable hypothesis.
- (D) also compares two types of plants but lacks a specific light condition.
Thus, the correct choice is (C) Pea plants will grow taller in red light than in blue light.
