Question

a student tests whether fertilizer increases tomato production. which are constants? tomato production water soil fertilizer light how many ml of water per day had the most seeds germinated? * 3 points water (ml) seeds sprouted 0 1 50 7 100 10

Explanation:

Step1: Identify constants in tomato - fertilizer experiment

In an experiment to test if fertilizer increases tomato production, factors like water, soil, and light should be kept constant to isolate the effect of fertilizer. Tomato production is the dependent variable and fertilizer is the independent variable being tested.

Step2: Analyze water - seeds germination data

From the table showing water (mL) and seeds sprouted, we can see that when 100 mL of water is given per day, 10 seeds sprouted which is the highest number compared to 0 mL (1 seed sprouted) and 50 mL (7 seeds sprouted).

Answer:

• Constants: Water, Soil, Light
• mL of water for most seeds germinated: 100
