Explanation

A ratio is a comparison of two values, often expressed as a fraction or a decimal.

It shows the relative size or quantity of one value in relation to another.

For example: A ratio of 3:4 (or 3/4) compares two values, 3 and 4.

Explanation

Once you have the data, you may need to perform mathematical analysis.

It involves using statistical and mathematical techniques to interpret and draw conclusions from the data.

Explanation

A scientific law is a statement that describes a consistent and universal pattern of natural behavior.

It is often considered an irrefutable theory.

Examples of scientific laws include the Law of Gravity, the Laws of Motion, and the Law of Conservation of Energy.

Explanation

The final step of the scientific method is developing a conclusion.

It involves summarizing the findings, interpreting the data, and determining whether the hypothesis was supported or rejected.

The scientific method steps in order:

• Observation
• Hypothesis
• Prediction
• Research
• Experimentation
• Data Analysis
• Conclusion

Explanation

Deductive reasoning is a type of logical reasoning that uses "if-then" statements to arrive at a conclusion.

It involves making a logical deduction based on a premise.

It is used in scientific reasoning to test hypotheses and predict outcomes.

Explanation

A hypothesis is a testable prediction that explains a phenomenon or solves a problem.

It's a crucial component of the scientific process, as it provides a framework for testing and experimentation.

Explanation

Observation is the first step in the scientific method, which is used to solve biological problems.

Scientists make observations about the natural world, notice patterns or phenomena, and ask questions about what they have observed.

The correct order of the scientific method is:

• Observation
• Question
• Hypothesis
• Prediction
• Experimentation
• Data analysis
• Conclusion

Explanation

The scientific method is a systematic approach used to develop and test scientific knowledge, including in biology and other sciences. It involves:

• Observations
• Hypothesis formation
• Prediction
• Experimentation
• Data analysis
• Conclusion drawing

Explanation

Radioactive isotopes, such as carbon-14 and uranium-238, decay at a steady rate.

It allowing scientists to measure the age of fossils and rocks.

This technique is known as radiometric dating.

Explanation

Fish is an excellent source of protein.

It is essential for building and repairing muscles, organs, and tissues in the body.
