Question
Brenda grew tadpoles in cages in 3 ponds and at two food levels (2 g food per L water and 0.2 g food per L water) within each pond. within each wild/illation of pond and food level (each combination Is considered a treatment), she had 3 replicate cages. She began the experiment with 100 tadpoles in each cage and at the end of the experiment she measured the body mass of each tadpole and the proportion of tadpoles surviving in each cage. What are the dependent variables? Survival, body mass What are the independent variable0 (also called factors) pond, food level How many experimental treatments did she have? (hint. each tadpole is reared or grown in a single treatment.) How many replicates did she have within each treatment? Should Brenda make inferences from her experimental results about the growth of tadpoles that would be raised at a food density of 3.0 g food per L water? Yes/ng explain briefly.Explanation / Answer
The dependend varaible is body mass
The independend varaible is pond
There are 300 tadpoles, So she had 300 treatments
Within each experiment she had 3 replicates
No, as no results are given yet
