BSC 108 Test 1 Chapters 1-4 Questions
Fully Solved 2026 Updated.
What is biology? - Answer The study of life
List the three domains. - Answer Eukarya, Bacteria, and Archae
List the four kingdoms in Eukarya. - Answer Animalia, Plantae, Fungi, and Protista
What are the properties of life? - Answer 1. They have order
2. Regulate themselves - homeostasis
3. Grow and Develop
4. Respond to the environment
5. They reproduce
6. Populations evolve
7. Use energy
How do you define something as living? - Answer Anything that is complex and made of
chemicals, something that needs to eat food, life cannot be defined.
What are some common themes in biology? - Answer The scope of life and emergent
properties, organisms exchange matter and energy within ecosystem, evolution, diversity is the
hallmark of life and the diverse forms of life fit their function, the continuity of life is based on
info in the DNA, cells are an organism's basic unit
What is the Scientific Method? - Answer A way to ask and answer scientific questions by
making observations and doing experiments. (Bacon created it)
List the steps of the scientific method. - Answer 1. Observe (The lamp is not working)
2. Question (Why isn't the lamp working?)
3. Hypothesize (The lamp isn't working b/c is is unplugged)
4. Predict
5. Experiment (Check to see if lamp is unplugged)
6. Analyze (Accept or Reject Hypothesis) (Accepted if lamp is unplugged; Rejected if lamp is
plugged in)
, What is a hypothesis? - Answer A proposed explanation for a set of observations; supported
not proven. A tentative explanation for an observation. "A possible solution to a problem, based
on knowledge and research" General Statement
What is a observation? - Answer "research" and first stage in understanding the problem you
have chosen
What is a prediction? - Answer Your prediction lets you get specific -- how will you
demonstrate that your hypothesis is true?
What is a control? - Answer A part of the experiment that is not being tested and is used for
comparison.
What are the components of a good hypothesis? - Answer 1. Description of the
observation/phenomenon to be explained.
2. A clear, logically coherent description of the process(es) hypothesized to cause the
observation/phenomenon.
3. A description of the consistency of the above descriptions with known facts and Accepted
theories.
4. A description of how the hypothesis may be falsified.
What is a theory in science? - Answer A well supported concept that has broad explanatory
power
What are the limits of science? - Answer Science cannot answer every question posed by man.
Religion and art are other methods to understand the world we live in.
What is an atom? - Answer Smallest unit of matter that retains the properties of an element
What is an atom composed of? - Answer Subatomic particles, which include protons,
neutrons, and electrons
Characteristics of atoms: - Answer -The number of protons, the atomic number, determines
which element it is.
-An atom's mass number (often called atomic weight) = the number of protons + neutrons.
-In a neutral atom the # electrons = # protons
What are the characteristics of a neutron? - Answer Neutrons are electrically neutral which
means no charge; atomic mass = 1 dalton
