Question

1. which of the following statements best describes a prediction? a the number of deformed frogs in five ponds that are polluted with chemical x is higher than the number of deformed frogs in five ponds without chemical x. b if the water in a pond has lower levels of pesticide then there will be less deformed frogs. c the number of deformed frogs is not affected by the presence of chemical x in the pond.

Explanation:

A prediction is a statement about what will happen in the future based on certain conditions. Option b presents a conditional - if the water has lower pesticide levels, then there will be a certain outcome (less deformed frogs), which is a prediction. Option a is a comparison of existing situations, and option c is a statement about non - relationship, not a prediction.

Answer:

b. If the water in a pond has lower levels of pesticide then there will be less deformed frogs.
