Design a controlled experiment to test the effect of water temperature on a goldfish. Be sure to include your hypothesis, independent variable, independent variable, as well as the experimental and control groups in your experiment

The experimental design involves three fish tanks each containing goldfish and sympatric non-competitive species populations composed of 100 individuals (N = 100), which must be maintained in three different temperature treatments.

Explanation:

1- First fish tank: water to the same temperature than its natural environment (for example 25 C)

2- Second fish tank: water temperature  2°C higher than its natural environment (27 °C)

3- Third fish tank:  water temperature  2°C lower than its natural environment (23 °C)

Null hypothesis: temperature treatments does not modify the survival of goldfish populations  

Independent variable: temperature treatments

Dependent variable: Goldfish survivance over n generations

Negative control: First fish tank (water to the same temperature than natural environment)

Control group: sympatric non-competitive species populations

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !

it is prolly d and c and f
