Biology Chapter 1 Review

Chapter 1 Lesson 1: Science is best defined as:

• The study of the natural world through observation and experimentation.

• A collection of opinions and beliefs.

• A set of unchanging facts.

• A way to guess about the world without evidence.

Hypotheses are important to controlled experiments because they provide:

• a basis for making predictions and guiding the experiment

• a guarantee that the experiment will succeed

• a way to avoid collecting data

• an explanation for every possible outcome

A theory differs from a hypothesis in that:

• a theory is a well-substantiated explanation, while a hypothesis is a testable prediction.

• a theory is a guess, while a hypothesis is a proven fact.

• a theory cannot be tested, while a hypothesis can.

• a theory is always incorrect, while a hypothesis is always correct.

Both curiosity and skepticism are useful in science because:

• they encourage asking questions and testing ideas.

• they prevent scientists from making any mistakes.

• they make science more complicated than necessary.

• they ensure all experiments are successful.

Peer review can help scientists improve their work by:

• providing feedback and suggestions from other experts

• ensuring all experiments are successful

• guaranteeing immediate publication

• eliminating the need for further research

The use of science is related to its context in society because:

• scientific developments are influenced by social needs and values.

• science is always separate from society.

• society does not affect scientific research.

• science only benefits scientists.

Testing ideas is an important part of all science and engineering practices because:

• it helps verify if ideas are correct or need improvement.

• it guarantees all ideas are always right.

• it makes experiments unnecessary.

• it prevents any mistakes from happening.

Living things differ from nonliving things in that they:

• can grow, reproduce, and respond to their environment

• are always visible to the naked eye

• do not require energy to survive

• are made only of non-organic materials

Crosscutting concepts help unite the study of biology by:

• providing a framework to connect different areas of biology

• focusing only on one specific biological process

• limiting the study to cellular biology

• ignoring patterns and relationships in nature

Biology can be studied at different scales, or levels, such as:

• molecules, cells, organisms, populations, and ecosystems

• only molecules and cells

• only organisms and populations

• only ecosystems and populations
