When scientists have made many observations and collected existing data, they suggest a possible explanation for what they have

seen and recorded. this explanation, called a hypothesis, is a statement that both explains their observations and data and can be tested. hypothesizing is a very important step in scientific investigations. a statement is testable if evidence can be collected that either supports or disproves it. a hypothesis may be shown to be wrong, but it can never be proved true beyond all doubt. it can only be supported by evidence. at any time, new data might indicate that a previously accepted hypothesis does not hold true in all instances. scientists often must refine and revise their original hypotheses—or even discard them—as they uncover new evidence. to test a hypothesis, scientists make a prediction that logically follows from the hypothesis. a prediction is a statement made in advance that states the results that will be obtained from testing a hypothesis, if the hypothesis is true. a prediction most often takes the form of an “if-then” statement. a hypothesis is often tested by carrying out an experiment. experimenting is the process of testing a hypothesis and its predictions by gathering data under controlled conditions.

A scientist finds fossae on a bone sample. what can the scientist conclude?
STatiana [176]
Fossae are holes or depressions in the bones that are usually found on the end of the long bones. Fossae are good indications that a bone was connected or articulated with another bone. Therefore, if a scientist has found a fossa on a bone he or she could conclude that the bone was joined with another bone in the skeleton at the place of the found fossa.
