Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A student places three identical plants in the same type of containers, uses the same type of soil and the same amount of water for each plant. This student places the three plants in three different locations. Plant A is placed in a sunny area, Plant B is placed in a shaded location, and Plant C is placed in the dark room. Each day this student records the growth of each plant. What is the different variable in this investigation?
A
the soil
B
the amount of water
C
the amount of light
D
the growth of each plant
Explanation: 

Detailed explanation-1: -When experimenting with the growth of a plant, a scientist uses three (of the same type of) plants, two different fertilizers, equal light, and equal water. What type of variable is the fertilizer? Independent.

Detailed explanation-2: -Loamy soil is ideal for most garden plants because it holds plenty of moisture but also drains well so that sufficient air can reach the roots.

Detailed explanation-3: -The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

Detailed explanation-4: -Soil is the primary source of nutrients and water, which are crucial for healthy plant development. The wrong soil can prevent your plants from getting the moisture and nutrients they need to grow and flourish.
