Question

lab: whats in the water?
temperature dissolved oxygen
winter
temperature dissolved oxygen
in the summer, what levels of dissolved oxygen would you expect compared to the winter?
very high levels of dissolved oxygen in the summer
equal levels of dissolved oxygen
dissolved oxygen cannot be compared
lower levels of dissolved oxygen in the summer

Explanation:

In water, the solubility of gases like oxygen is temperature - dependent. As temperature increases, the solubility of oxygen in water decreases. Summer has higher temperatures compared to winter. So, we would expect lower levels of dissolved oxygen in summer compared to winter.

Answer:

lower levels of dissolved oxygen in the summer
