Hi everyone here we have a question asking which of the following statements are true about hypotheses and theories. A theories are based on extensive data while hypotheses are based on limited information. This is true. Now let's see why the others are incorrect. B theories are not scientifically tested or proven. While hypotheses are scientifically tested to be proven. This is opposite theories are scientifically tested and proven and hypotheses are not. So we is incorrect. See theories are predictions and suggestions. While hypotheses are supported by evidence, theories are supported by evidence while hypotheses are predictions and suggestions of C. Is incorrect. D. The theory is a widely accepted explanation of the specific phenomenon and therefore cannot be falsified. Unlike a hypothesis. Even though a theory is scientifically tested and proven it can be falsified if there is more information that comes to light so D. Is incorrect. So our answer here is a theories are based on extensive data. While hypotheses are based on limited information. Thank you for watching. Bye.
