General Biology Quiz 1 Study Guidance

Q1. Which characteristics distinguish living organisms from non-living things? (Put an X for each trait that applies to living organisms.)

Background

Topic: Characteristics of Life

This question tests your understanding of the fundamental traits that define living organisms and separate them from non-living matter.

Key Terms:

• Living organisms: Entities that exhibit the basic characteristics of life, such as metabolism, growth, reproduction, and response to stimuli.

• Traits of life: Common features shared by all living things, including the use of energy, reproduction, and genetic information.

Step-by-Step Guidance

1. Review the list of traits provided (e.g., movement, reproduction, use of energy, genetic plan, making proteins).

2. Recall the main characteristics of living organisms: organization, metabolism (use of energy), homeostasis, growth, reproduction, response to stimuli, and adaptation.

3. For each trait, ask yourself: "Is this something all living things do, or only some?" For example, not all living things move, but all use energy.

4. Mark an X for each trait that is a universal characteristic of life, and leave blank those that are not required for all living things.

Final Answer:

The traits that apply to all living organisms are:

• Living organisms use energy.

• Living organisms make proteins.

• Living organisms can reproduce.

• Living organisms have a genetic plan.

Not all living things can move or change by selection as individuals, so those are not universal traits.

Q2. Which of the following is an emergent property relative to the structure of cells?

Background

Topic: Emergent Properties in Biology

This question is about understanding how new properties arise at higher levels of biological organization, specifically at the cellular level.

Key Terms:

• Emergent property: A characteristic that appears when individual components interact at a higher level of organization, not present in the individual parts alone.

• Cell: The basic unit of life, capable of performing all life processes.

Step-by-Step Guidance

1. Read each answer choice and consider whether the property described is something that arises from the interaction of multiple cells, rather than from a single cell alone.

2. Recall that emergent properties are new abilities or functions that appear when components combine (e.g., tissues, organs).

3. Identify which option describes a function or property that is not present in single cells but emerges when cells work together.

Final Answer:

The correct answer is: B. Cells work with other cells to make complex organs and organ systems.

This is an emergent property because the ability to form organs and organ systems only arises when many cells interact and organize together.

Q3. Science is generally described as two very different, yet connected things. What are they?

Background

Topic: Nature of Science

This question tests your understanding of the dual nature of science: as a body of knowledge and as a process or method.

Key Terms:

• Science as a process: The systematic method of inquiry used to investigate natural phenomena.

• Science as knowledge: The collection of facts, explanations, and theories developed through scientific inquiry.

Step-by-Step Guidance

1. Think about how science is both a way of learning about the world and the information we gain from that process.

2. Identify the two aspects: one is the method (how we learn), and the other is the result (what we know).

3. Phrase your answer to reflect both the process and the body of knowledge.

Try solving on your own before revealing the answer!

Final Answer:

The two connected things are: 1) the process of learning how things work (scientific method), and 2) the body of knowledge we accumulate about the natural world.

Science is both a way of discovering information and the collection of information itself.

Q4. Which of the following does not exist in science? (laws, theories, hypotheses, proof) Explain your answer.

Background

Topic: Scientific Method and Terminology

This question is about understanding the terminology used in science and why certain terms are not appropriate.

Key Terms:

• Law: A statement based on repeated experimental observations that describes some aspect of the world.

• Theory: A well-substantiated explanation of some aspect of the natural world.

• Hypothesis: A testable prediction or explanation for a phenomenon.

• Proof: Absolute certainty; in science, nothing is ever proven beyond all doubt, only supported by evidence.

Step-by-Step Guidance

1. Review the definitions of each term and consider how they are used in scientific practice.

2. Recall that science relies on evidence and repeated testing, but does not claim absolute proof.

3. Identify which term is not consistent with the scientific approach to knowledge.

Try solving on your own before revealing the answer!

Final Answer:

The correct answer is: Proof

Science does not deal in absolute proof; instead, it builds evidence to support or refute hypotheses and theories. Scientific knowledge is always open to revision with new evidence.

Q5. Normal people (non-scientists) often describe "theories" about how something works. Scientifically, these are more accurately considered as...

Background

Topic: Scientific Terminology

This question is about the difference between the everyday and scientific use of the word "theory." In science, a theory is a well-supported explanation, while in everyday language, it often means a guess or hypothesis.

Key Terms:

• Theory (scientific): A comprehensive explanation supported by evidence.

• Hypothesis: A testable idea or prediction.

Step-by-Step Guidance

1. Recall the difference between a scientific theory and a hypothesis.

2. Think about how people use the word "theory" in everyday conversation (often meaning a guess or idea).

3. Identify the scientific term that matches this everyday usage.

Try solving on your own before revealing the answer!

Final Answer:

The correct answer is: Hypotheses

In science, what most people call a "theory" is actually a hypothesis—a testable idea or explanation, not a well-established theory.
