Final answer:
Deductive reasoning is a form of logical thinking that uses a general principle or law to predict specific results. It involves moving from a general theory to a specific conclusion based on observation and evidence. Scientists commonly use deductive reasoning in hypothesis-based science.
Step-by-step explanation:
Deductive reasoning, also known as deduction, is a form of logical thinking that uses a general principle or law to predict specific results. It involves moving from a general theory to a specific conclusion based on observation and evidence. For example, scientists can use deductive reasoning to predict that if the climate becomes warmer in a particular region, then the distribution of plants and animals should change. Deductive reasoning is commonly used in hypothesis-based science.
