Answer
25. What is the dependent variable in a study investigating the effect of water pollution on freshwater mussels in the Anacostia River?
a) Water pollution levels
b) Freshwater mussel populations
c) The temperature of the water
d) The presence of invasive species
Answered by GPT-4o mini
The correct answer is **c) Evaporation of water from plants contributes to atmospheric humidity**.

This choice specifically highlights the interaction between the biosphere (plants) and the atmosphere in the context of the water cycle, where transpiration from plants releases water vapor, contributing to humidity in the atmosphere.

While the other options describe interactions, option c is the most direct concerning the specific relationship within the water cycle.

The correct answer is **a) Hydrological hazard**.

Hydrological hazards are associated with water-related phenomena, including flooding from river overflow or excessive rainfall.

The correct answer is **b) Freshwater mussel populations**.

In an experiment investigating the effect of water pollution on freshwater mussels, the dependent variable is what you measure or observe in response to changes in the independent variable. In this case, the freshwater mussel populations would be affected by the levels of water pollution, making them the dependent variable.
