EXAM QUESTIONS
QUESTION 1
Scientific Method
CORRECT ANSWER
A logical, systematic approach to the solution of a scientific problem by asking a question, forming a
hypothesis, and performing an experiment
RATIONALE: This correct description of the scientific method encompasses the essential steps in the process, including
formulating questions, generating testable hypotheses, and conducting experiments to validate or reject those hypotheses.
It represents a structured approach to scientific inquiry that helps researchers to gather reliable data, draw informed
conclusions, and contribute to the advancement of scientific knowledge.

, QUESTION 2
Measurement
CORRECT ANSWER
the certain digit plus one estimated number (example: 4.0 cm or 10.7 in.)
RATIONALE: The correct answer is "the certain digit plus one estimated number" because it represents a measurement
that includes a precise value (the certain digit) and an approximation or range (the estimated number), which is often
necessary to provide a complete and realistic measurement. This format acknowledges that measurements can be subject
to some degree of uncertainty or variation, allowing for a more accurate and practical representation of the measured
quantity.
QUESTION 3
significant figures
CORRECT ANSWER
1. Non-zero digits are not significant (ex: 145.98)
2. Zeroes between significant digits are significant (ex: 1002)
3. Zeroes which precede all non-zero digits are not significant (ex: 0.0045)
RATIONALE: Non-zero digits are considered significant because they carry meaningful information and contribute to the
precision of a measurement or value, whereas zeroes without non-zero digits preceding them do not provide any additional
information. The placement of zeroes in relation to non-zero digits is crucial, as it indicates whether a measurement or
value has been rounded or is an exact representation, allowing for accurate calculations and comparisons.
QUESTION 4
Biotic vs. Abiotic
CORRECT ANSWER
Living vs. nonliving
Examples: Biotic- Plants/Abiotic-water
RATIONALE: The terms "biotic" and "abiotic" are categories used to classify factors or components in an ecosystem. The
correct pairing "Living vs. nonliving" is based on the definitions of "biotic" (relating to living organisms) and "abiotic"
(relating to nonliving components), making the example "Biotic- Plants/Abiotic-water" a correct representation of the biotic
vs. abiotic relationship.

, QUESTION 5
Trophic Levels of a Food chain
CORRECT ANSWER
producer, primary consumer, secondary consumer, tertiary consumer
RATIONALE: The correct sequence of trophic levels in a food chain is based on the feeding relationships between
organisms, where primary producers, typically plants, are consumed by primary consumers, such as herbivorous animals,
which in turn are consumed by secondary consumers, like carnivorous animals that feed on herbivores. The progression
continues from secondary to tertiary consumers, which feed on secondary consumers, showcasing the hierarchical structure
of the food chain.
QUESTION 6
Producers vs. Consumers
CORRECT ANSWER
Producers- make own food
Consumers- need to consume a living thing
RATIONALE: This answer is correct because it accurately distinguishes between organisms that synthesize their own food
through photosynthesis or chemosynthesis, and those that obtain energy by consuming and breaking down other living
things. The key concept is that producers, like plants and some bacteria, create their own food, whereas consumers, like
animals and humans, rely on consuming other organisms to sustain themselves.
QUESTION 7
Heterotrophs
CORRECT ANSWER
organisms that cannot make their own food
RATIONALE: Heterotrophs are organisms that cannot produce their own food through photosynthesis or other means,
relying on consuming other organisms or organic matter for energy. This characteristic is key to defining heterotrophs, as it
sets them apart from autotrophs, which can create their own food through various processes.
