I was wondering if you can check to see if these are good predications, hypothesis and questions. Like does the grammar makes and stuff. Thank you

Hypothesis : Temperature as one, environmental factor will affect the physiological functioning of the small organism Daphnia.

Question: What is the effect of the presence of temperature on the heart rate of a organism.

Predictions: The Daphnia heart will increase or beat at a higher rate if the temperature rises and beat at a slower rate if decreased.

1. Delete the comma in Hypothesis.

2. Delete "increase or" in Predictions.
