Correct Answer: 1. Order, 2. Sensitivity/Response to Stimuli, 3. Reproduction, 4. Adaptation, 5. Growth
& Development, 6. Regulation/Homeostasis, 7. Energy Processing, 8. Evolution.
Question: What is the basic unit of life?
Correct Answer: The cell is the basic unit of life.
Question: What is a Prokaryote vs. Eukaryote?
Correct Answer: Prokaryotes are single-celled organisms without a nucleus, while Eukaryotes are
organisms whose cells contain a nucleus and organelles.
Question: What is homeostasis?
Correct Answer: Homeostasis is the process by which living organisms maintain a stable internal
environment despite external changes.
Question: What is thermoregulation?
Correct Answer: Thermoregulation is the process of maintaining an optimal temperature in the body.
Question: What is ATP?
Correct Answer: ATP (adenosine triphosphate) is the primary energy carrier in cells.
Question: What is evolution?
Correct Answer: Evolution is the change in the heritable characteristics of biological populations over
successive generations.
Question: What is Taxonomy?
Correct Answer: Taxonomy is the science of classification of living organisms.
Question: What are the three domains of life?
Correct Answer: The three domains of life are Archaea, Bacteria, and Eukarya.
Question: What is the binomial naming system?
Correct Answer: The binomial naming system is a formal system of naming species using two names: the
genus name and the species name.
Question: What is the scientific method?
Correct Answer: The scientific method is a systematic approach to inquiry that involves observation,
hypothesis formulation, experimentation, and conclusion.
Question: What is a hypothesis?
Correct Answer: A hypothesis is a testable and falsifiable statement predicting the outcome of a scientific
investigation.
, Question: What is a Scientific Theory?
Correct Answer: A scientific theory is a well-substantiated explanation of an aspect of the natural world
that is based on a body of evidence.
Question: What is inductive reasoning?
Correct Answer: Inductive reasoning involves making generalizations based on specific observations.
Question: What is deductive reasoning?
Correct Answer: Deductive reasoning involves drawing specific conclusions from general principles or
premises.
Question: What is a peer-review article?
Correct Answer: A peer-review article is a scholarly article that has been evaluated and critiqued by
experts in the field before publication.
Question: What is Bioethics?
Correct Answer: Bioethics is the study of ethical issues emerging from advances in biology and medicine.
Question: What are the four most abundant elements in the human body?
Correct Answer: The four most abundant elements in the human body are oxygen, carbon, hydrogen, and
nitrogen.
Question: What is an atom?
Correct Answer: An atom is the smallest unit of matter that retains the properties of an element.
Question: What are the three subatomic particles?
Correct Answer: The three subatomic particles are protons (positive charge), neutrons (no charge), and
electrons (negative charge).
Question: What is a chemical bond?
Correct Answer: A chemical bond is a lasting attraction between atoms that enables the formation of
chemical compounds.
Question: What is an ion?
Correct Answer: An ion is an atom or molecule that has a net electrical charge due to the loss or gain of
one or more electrons.
Question: What is a cation?
Correct Answer: A cation is a positively charged ion, formed by the loss of electrons.
Question: What is an anion?
Correct Answer: An anion is a negatively charged ion, formed by the gain of electrons.
Question: What is a covalent bond?
Correct Answer: A covalent bond is a type of chemical bond where two atoms share one or more pairs of
electrons.
Question: What is a hydrogen bond?
