Question
, you will give the three groups of GM corn plants different amounts of water.As a class, identify variables or factors that you will need to keep the same between the three groups to ensure a fair test.
Solution
To ensure a fair test in this experiment, you will need to control several variables across the three groups of GM corn plants. Here are some factors that should be kept the same:
-
Light Exposure: All groups should receive the same amount of light each day. Light is a crucial factor for plant growth, and differences in light exposure could affect the results.
-
Soil Type and Quality: The soil used for all groups should be of the same type and quality. Different soils can have varying amounts of nutrients, which could influence plant growth.
-
Temperature: The temperature in the environment where the plants are grown should be consistent for all groups. Temperature can affect the rate of plant growth and development.
-
Plant Age: The plants in each group should be of the same age. Older plants might react differently to water amounts than younger ones.
-
Plant Variety: All plants should be of the same variety of GM corn. Different varieties may have different growth rates and responses to water.
-
Pot Size: If the plants are grown in pots, the size of the pots should be the same for all groups. The pot size can influence root development and overall plant growth.
By controlling these variables, you can ensure that any differences observed in the growth of the plants are due to the different amounts of water each group received, not other factors.

A corn farmer is interested in reducing the number of days it takes for his corn to silk. He has decided to set up a controlled experiment that manipulates the nominal variable “fertilizer,” having two categories: 1 = limestone and 2 = nitrogen. Another nominal variable is “soil type,” with two categories: 1 = silt and 2 = peat.
450kg of maize has a moisture content of 15% on dry basis. How much water does it contain?
Two experimental fields were each planted with corn. Fertilizer was added to the first field but not to the second. The first field produced 250 bushels of corn per acre and the second field produced 180 bushels of corn per acre. Since nothing else but water was added to either fields, the higher yield in the first field must be due to the fertilizer.Which of the following, if true, most seriously weakens the argument above?radio_button_uncheckedA small amount of the fertilizer leached into the second field.radio_button_uncheckedFour different types of corn grown in equal proportions in each of the fields.radio_button_uncheckedSome weeds that compete with corn cannot tolerate high amounts of fertilizer in the soil.radio_button_uncheckedThe two experimental fields were located in different states.
