Botanists are scientists who study plants. A group of botanists is working to determine which type of fertilizer is the most successful in fertilizing the soybean plants that they are experimenting with.Soybean Plant by Julio César García (CC0)Which of the following is an example of a testable hypothesis for this scenario?Elimination ToolSelect one answerASoybean plants fertilized with Fertilizer A will grow fifty times more than plants fertilized with Fertilizers B and C.BTen soybean plants fertilized with Fertilizer A will grow more quickly, on average, than five soybean plants fertilized with Fertilizer B.CFive soybean plants fertilized with Fertilizer A will grow more quickly, over ten days, than five soybean plants fertilized with Fertilizer B.DSoybean plants will grow faster with water than without water.

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.

Adding more fertilizer does NOT necessarily increase crop production. This is an example ofA. the law of supply and demandB. Leibig's law of minimumC. limiting factorsD. the second law of thermodynamicsE. the Gaia hypothesis

When testing the benefits of a new fertilizer on the growth of calamansi plants, the control group should include which of the following?a.Calamansi plants grown in soil with the original type of fertilizerb.Calamansi plants grown in soil with the original type of fertilizerc.Calamansi plants grown in soil with no fertilizerd.Calamansi plants grown in a different type of soil with the new fertilizer
