Answer:
<u>scientist general conduct test and analysis by experimenting data that leads to formation of hypothesis for the study.</u>
Explanation:
- A hypothesis is an explanation of the phenomenon and for a hypothesis to be scientifically true it must be tested as generally based on observations, which is an unproven phenomenon in which needs to be testes first and the explanation in terms of facts or figures are thus a part of the data.
- A hypothesis relies on the prediction and suggestions of facts while a theory is supportive of the evidence. Hense a theory has to be accurate and not an experimental basis.
- Thus it will be considered as a hypothesis as to its more subjective explanation and a work in progress.
yes it is right according to my research

Cyanobacteria's excrement formed a lot of oxygen in the atmosphere which make the earth temperature cold
This allow a liquid water to formed on the surface ( because if the temperature is too high, the water will evaporate) and eventually formed oceans
