Answer:

(b) diameter of the cotton bolls in both fields

Explanation:

According to the hypothesis, the application of magnesium to cotton plants would support the growth of large cotton bolls. The field without magnesium would serve as control here. Cotton bolls from both the fields should be collected and their diameter should be measured.

If the diameter of the cotton bolls from the field with magnesium application is more than that of the cotton bolls from the control field with no magnesium, the hypothesis is correct. Therefore, measurement and comparison of the diameter of cotton bolls from the experimental and control field would allow the student to check the hypothesis.

The answers to the questions required for the design experiment above are :

  • If shark attack are related to the number of elephant seals in an area, then shark attack will increase as the number of elephant seal increases

  • If shark attack are unrelated to number of elephant seal in an area, then shark attack is unaffected by increase or decrease in number of elephant seal.

  • The Control Group : Beaches or areas where elephant seals aren't present or period of the year when there are no elephant seal at the beach.

  • The Experimental group : Beaches where varibale portions of elephant seals are found (area with high, medium or low).

  • The Dependent variable : Number of shark attacks

  • The Independent variable : The different number of elephant seals found.

  • Data to be collected include : The number and type of elephant seals found at various beaches and the number of shark attacks recorded at the various points.

  • John will be able to deduce if the number of elephant seals and number of shark attacks recorded corded are related.

The hypothesis of an experiment is a proposition which requires experimental testing in other to establish it's validity.

The Control Group refers to a portion of the subject which aren't given or exposed to the treatment used in an experiment.

The Experimental group are the portion of the subjects which are subjected to the treatment condition.

The Dependent variable is the measured variable is changes as the independent variables are tweaked.

Independent variable is the predictor variable, it causes a change in the output of the dependent variable.
