what would be valid hypothesis for this experiment?
○ a if the scientist use pea plants, then there will be a lot of growth
○ b if the light is red, the plants will grow
○ c if plants are grown under different colored lights, then they will grow different heights.
○ d if a month passes, then the plants will grow under the red light

students will benefit greatly from having homework each night, therefore, they should be assigned it regularly.

○ b reasoning

○ d support

Explanation:

Question 24

• Option a: Focuses on pea plants, not red light’s effect. Eliminate.
• Option b: Links red light (independent variable) to plant growth (dependent variable), fitting the experiment’s goal.
• Option c: Compares different colored lights, not just red. Eliminate.
• Option d: Confuses time passage with growth under red light. Eliminate.

• A claim is a statement asserting a position. The sentence states students benefit from nightly homework and should get it, which is a claim. Reasoning (b) explains “why,” evidence (c) is data, support (d) backs a claim—this is a claim itself.

Answer:

b. If the light is red, the plants will grow
