Which is the best hypothesis for the scientific question “how does light intensity affect the rate of photosynthesis? ”

Answer;

d) light intensity has an impact on the rate of photosynthesis.

explanation; hypothesis are ideas that can be tested using experimentation or scientific experiments. these ideas are based on observation or previous experience or knowledge. hypothesis are possible explanation attached to some observations or answers to a scientific question. experiments are carried out to test hypothesis. in this case, the hypothesis "light intensity has an impact on the rate of photosynthesis" is answering the scientific question, “how does light intensity affect the rate of photosynthesis? ”

The different light intensities can affect the rate of photosynthesis.
there is a significant relationship between the different light intensities and rate of photosynthesis.

a hypothesis is a supposition made by the scientist. in order for a hypothesis to be a scientific hypothesis, the scientific method requires for it to be tested. if a hypothesis cannot be tested, it cannot be scientific hypothesis. it is important to state the hypothesis clearly at the beginning of a scientific paper. this enables the reader to understand the problem.
