Revisions to predictions about scientific phenomena can be based on

The correct answer is D. All of these

Explanation:

Scientific predictions are based on previously recorded information, which includes observations, data gathered with precise instruments, mathematical models, measurements, among others. This allows scientists to understand phenomena objectively by using the scientific method and to make accurate predictions.

Despite this, scientific predictions might slightly, or completely change over time. This is because new tools or methods might provide scientists with new contradictory evidence about the phenomenon. Moreover, any type of evidence gathered as part of the scientific method is valid to evaluate a previous prediction such as observations, data, models, measurements, among others.

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less
