Answer:

control group

Question 6: information gained from observations

Answer:

data Question 7: Is one test of the experiment all that is necessary for a scientific investigation

Answer:

No ... the investigation must be repeated many times to obtain consistent results Question 8: type of data that are descriptions of what our senses detect ( interpretations vary as not all sense things in the same way)

Answer:

qualitative Question 9: Biologist often work in teams.. and hold meetings to discuss on goin investigations, analyse data and interpret results... it is also important to Avoid__B____, repeat trials to get a large ___

Answer:

Bias...... large sample size Question 10: What are two possible fates of a hypothesis that has been tested... when supported and when not supported

Answer:

a hypothesis supported by data from additonal investigations , it is usually considered valid and accepted by scientific community.. hypothesis not supported is revided and more investigations occur
