Answer 1

Bryce should examine the skin of dogs with and without fleas to look for bite marks to test his prediction.

Step-by-step explanation:

Bryce should test his prediction by examining the skin of dogs with and without fleas to look for bite marks. By comparing the presence or absence of red bite marks in these two groups, Bryce can determine if the presence of fleas is correlated with the appearance of bite marks. This will provide evidence to support or refute his prediction.
