After а stоrm, аlgаe increase in a campus pоnd. Hypоthesis 1 states that nitrate runoff caused the increase. Hypothesis 2 states that warmer water caused the increase.

Increasing temperature within the observed pond range while holding nitrate constant does not change algal growth. Which conclusions are justified? Select all that apply.
