GUIDE 2026 SOLVED QUESTIONS FULLY
CORRECT
⫸ What are the seven characteristics of life? Answer: 1. Reproduction -
asexual or sexual; 2. Growth and development - organisms develop over
time; 3. Energy use - intake, conversion, and expulsion of energy; 4.
Cells - all living things are made of cells; 5. Order - organized structure
from atoms to biosphere; 6. Response to environment - maintaining
homeostasis; 7. Evolution - organisms adapt and evolve over time.
⫸ Are viruses considered living organisms? Why or why not? Answer:
Viruses are not considered living because they cannot reproduce
independently and require a host cell to replicate.
⫸ What is science? Answer: Science is a dynamic process of studying
the natural world through observation and experimentation, aiming to
support or refute hypotheses.
⫸ What is science not? Answer: Science is not absolute proof, a set of
unchangeable facts, or based on belief; it is always open to revision with
new evidence.
, ⫸ Define a scientific fact. Answer: A fact is an observation that has
been repeatedly confirmed and is accepted as true.
⫸ Define a hypothesis. Answer: A hypothesis is a tentative, testable
statement that can be supported or refuted by experiments or
observations.
⫸ Define a scientific theory. Answer: A theory is a well-substantiated,
highly probable explanation for a set of phenomena based on repeated
testing and evidence.
⫸ Define a scientific law. Answer: A law is a statement describing
observed patterns in nature, often expressed mathematically, without
explaining why the pattern occurs.
⫸ What is the hypothetico-deductive approach to science? Answer: A
process to investigate phenomena: Observation, Question, Hypothesis,
Empirical test, Conclusion.
⫸ What does it mean for science to be testable? Answer: A hypothesis
is testable if predictions can be made and experiments can be conducted
to confirm or reject it.
⫸ What does it mean for science to be repeatable? Answer: Results are
considered scientific if other researchers can repeat the same
experiments under the same conditions and obtain similar results.
