Question

Fiona wants to use the scientific method to answer the question "Do oxygen levels in the air of photosynthesis?" She reads about photosynthesis in her biology book and is ready to carry the next step. should she do next? O perform an experiment design a procedure make observations a hypothesis

Answer 1

The correct answer is D!:)

Step-by-step explanation:

Hope this helps!:)

Answer 2

Answer: hypothesis, prediction, design experiment, carry out experiment, etc

Explanation:If the question is supposed to be, is there a connection between atmospheric oxygen level and photosynthesis, then the next step would be to frame the hypothesis, which could be, for example,

“photosynthesis requires oxygen”, and a prediction such as,,

in a closed system, photosynthesis will reduce the oxygen level, or even photosynthesis does not proceed without oxygen.

and a format to test the hypothesis (design an experiment)

perform the experiment

collect data

analyse data

(of course, in this case, the data will support the null hypothesis).
