Question 10

You want to test how water temperature affects the size of adult frogs.You have two temperature treatments,one at 5 degrees Celsius (5 C)and the other at 15 degrees Celsius (15 C).You hatch and rear tadpoles at both of these temperatures.According to your knowledge of how temperature affects the final size of an organism,your prediction should be that:

Accepted Answer

A)  Tadpoles in 15 C water will develop faster and therefore have a larger final size relative to tadpoles in the 5 C treatment. 
B)  Tadpoles in 15 C water will develop faster and therefore have a smaller final size relative to tadpoles in the 5 C treatment. 
C)  Tadpoles in 5 C water will develop faster and therefore have a larger final size relative to tadpoles in the 15 C treatment. 
D)  None of the above 
A)  Tadpoles in 15 C water will develop faster and therefore have a larger final size relative to tadpoles in the 5 C treatment. 
B)  Tadpoles in 15 C water will develop faster and therefore have a smaller final size relative to tadpoles in the 5 C treatment. 
C)  Tadpoles in 5 C water will develop faster and therefore have a larger final size relative to tadpoles in the 15 C treatment.
