Question

debbie is fishing with her grandfather at a lake. to identify the type of fish she just caught, which of the following should she most likely use? (1 point) dichotomous key for salt-water fish using qualitative traits dichotomous key for fresh-water fish using qualitative traits qualitative traits such as weight, height, and number of fins quantitative traits such as eye color, skin color, and texture

Explanation:

1. Analyze the environment: Debbie is fishing at a lake, which is a freshwater body, so a salt - water fish key is inappropriate (eliminates the first option).
2. Differentiate qualitative and quantitative traits: Weight, height are quantitative (eliminates the third option as it misclassifies them as qualitative). Eye color, skin color, texture are qualitative, but the option misclassifies them as quantitative (eliminates the fourth option).
3. The second option uses a dichotomous key for freshwater fish (correct environment) and qualitative traits (suitable for identification), so it's the best choice.

Answer:

B. Dichotomous key for fresh - water fish using qualitative traits
