Below are sample questions representative of the exercises included on this worksheet and related 7.23 Environmental and Genetic Factors in Growth skill assessments:

Problem 1Difficulty: Mastery

A report compares two groups of soybean plants. Group 1 came from Family group 1 and was grown with water every fourth day. Group 2 came from Family group 2 and was grown with water every day. Group 1 averaged 10 cm tall, and Group 2 averaged 13 cm tall. What is the best scientific critique of this comparison?

AFor the soybean plants, it proves only watering schedule affected growth because the two groups also came from different inherited lines.

BFor the soybean plants, it proves only genes affected growth because Group 1 and Group 2 were grown with different watering schedule conditions.

CFor the soybean plants, the comparison is confounded because both inherited background and watering schedule changed, so the cause of the growth difference cannot be isolated.

DFor the soybean plants, it is a perfect fair test because changing Family group 1/Family group 2 and watering schedule at the same time makes results easier to interpret.

Solution & Explanation:A fair test should change one variable at a time. Because both inherited background and watering schedule changed, the data do not show which factor caused the growth difference.

Problem 2Difficulty: Mastery

A report compares two groups of spinach plants. Group 1 came from Cultivar North and was grown with deep shade. Group 2 came from Cultivar South and was grown with bright indirect light. Group 1 averaged 9 cm tall, and Group 2 averaged 16 cm tall. What is the best scientific critique of this comparison?

AFor the spinach plants, it proves only shade affected growth because the two groups also came from different inherited lines.

BFor the spinach plants, the comparison is confounded because both inherited background and shade changed, so the cause of the growth difference cannot be isolated.

CFor the spinach plants, it proves only genes affected growth because Group 1 and Group 2 were grown with different shade conditions.

DFor the spinach plants, it is a perfect fair test because changing Cultivar North/Cultivar South and shade at the same time makes results easier to interpret.

Solution & Explanation:A fair test should change one variable at a time. Because both inherited background and shade changed, the data do not show which factor caused the growth difference.

Problem 3Difficulty: Mastery

A report compares two groups of marigold plants. Group 1 came from Strain R and was grown with small pots. Group 2 came from Strain S and was grown with larger pots. Group 1 averaged 8 cm tall, and Group 2 averaged 14 cm tall. What is the best scientific critique of this comparison?

AFor the marigold plants, it proves only root space affected growth because the two groups also came from different inherited lines.

BFor the marigold plants, it proves only genes affected growth because Group 1 and Group 2 were grown with different root space conditions.

CFor the marigold plants, it is a perfect fair test because changing Strain R/Strain S and root space at the same time makes results easier to interpret.

DFor the marigold plants, the comparison is confounded because both inherited background and root space changed, so the cause of the growth difference cannot be isolated.

Solution & Explanation:A fair test should change one variable at a time. Because both inherited background and root space changed, the data do not show which factor caused the growth difference.
