A reaction that absorbs heat from the surroundings
A reaction that only occurs at high temperatures
A reaction that releases heat to the surroundings (Correct answer)
A reaction that requires light to proceed

S phase
G2 phase
G1 phase (Correct answer)
M phase

Correct answer: G1 phase

The movement and alignment of chromosomes during cell division is a characteristic of the metaphase stage of mitosis. Therefore, if the students are observing an onion cell under a microscope and they notice that the chromosomes are aligning themselves, the onion cell must be in the metaphase stage of mitosis.

Question 85: What is the greatest common divisor (GCD) of 84 and 120?

24 (Correct answer)
6
42
12

Correct answer: 24

Using the Euclidean algorithm: GCD(120, 84) = GCD(84, 36) = GCD(36, 12) = 12... wait, GCD(84,120): 120=1×84+36, 84=2×36+12, 36=3×12+0, so GCD=12.

A number that cannot be expressed as a fraction

Correct answer: Any number that can be written as p/q where p and q are integers and q ≠ 0

A rational number is any number expressible as the ratio p/q of two integers where the denominator is not zero.

Identifying a word that does not belong in a group of three spoken words (e.g., gate, game, shake)
Recognizing that two words contain the same sound (e.g., thin and path)
Identifying the initial sound in a word (e.g., /b/ in bed) (Correct answer)

Correct answer: Identifying the initial sound in a word (e.g., /b/ in bed)

Identifying the initial sound in a word (e.g., /b/ in bed) is typically the easiest phonemic awareness skill for children to acquire.

Question 90: What does data integrity mean in CSET practice?

The artistic quality of data visualizations
The physical security of computer hardware
The speed at which data can be processed
The accuracy, consistency, and reliability of data throughout its entire lifecycle (Correct answer)

Correct answer: The accuracy, consistency, and reliability of data throughout its entire lifecycle

Data integrity refers to maintaining and assuring the accuracy, consistency, and reliability of data over its entire lifecycle, ensuring that information remains trustworthy for analysis and decision-making.

Question 91: Which process converts glucose into pyruvate without using oxygen?

The citric acid cycle
Glycolysis (Correct answer)
Beta-oxidation
Oxidative phosphorylation

Correct answer: Glycolysis

Glycolysis occurs in the cytoplasm and splits glucose into two pyruvate molecules, producing a net gain of 2 ATP.

Question 92: What does professional competency require of a CSET practitioner?

Accepting all work regardless of personal qualifications
Learning only during initial formal schooling or training
Relying solely on the original certification training received
Maintaining current knowledge through continuing education within qualified areas (Correct answer)

Correct answer: Maintaining current knowledge through continuing education within qualified areas

Professional competency requires ongoing education, staying current with field developments, and practicing only within demonstrated areas of qualification.

Question 93: Which kingdom includes organisms that are multicellular, obtain nutrients by absorption, and have cell walls made of chitin?

Animalia
Fungi (Correct answer)
Protista
Plantae

Correct answer: Fungi

Fungi are multicellular absorptive heterotrophs with chitin-containing cell walls, distinguishing them from plants and animals.

Question 94: What is trend analysis in CSET reporting?

Predicting the exact future with complete certainty
Comparing a single data point to a historical average
Examining data over time to identify patterns, directions, and changes in performance (Correct answer)
Analyzing current fashion trends in the industry

Correct answer: Examining data over time to identify patterns, directions, and changes in performance

Trend analysis examines historical data across multiple time periods to identify patterns, direction of change, and rate of change, helping predict future performance and inform strategic decisions.

Question 95: How do regulations differ from industry standards in CSET practice?

Regulations apply only to individuals, not organizations
Standards are always stricter than regulations
Regulations are legally binding; standards are typically voluntary guidelines (Correct answer)
They are exactly the same thing in all contexts

Correct answer: Regulations are legally binding; standards are typically voluntary guidelines

Regulations are legally enforceable rules from government agencies, while standards are developed by industry bodies and are typically voluntary, though they may become requirements through regulatory adoption.

Question 96: What is the first step in CSET risk assessment?

Identifying potential hazards and threats relevant to the activity or project (Correct answer)
Purchasing insurance coverage immediately
Ignoring minor risks to focus on major ones
Assigning blame for past incidents

Correct answer: Identifying potential hazards and threats relevant to the activity or project

Risk assessment begins with systematic identification of all potential hazards and threats, as you cannot manage risks you haven't identified. This foundation supports all subsequent analysis and mitigation.

Question 97: The microbiology class instructor discusses amoebiasis, a disease brought on by the amoeba, a unicellular organism. On the screen, a tagged image of an amoeba cell is shown. It has a nucleus along with the cytoplasm, mitochondria, and other organelles. What type of cell is an amoeba based on the prokaryotic and eukaryotic cell structures?

It is a eukaryotic cell because it has a nucleus that encloses the DNA and separates it from the other organelles (Correct answer)
It is a prokaryote because it is a unicellular organism, which means that its structure is primitive and not complex
It is a eukaryotic cell because it has cytoplasm that is enclosed in a cell membrane
It is a prokaryotic cell because it does not have a chloroplast, which aids in producing its own food

Correct answer: It is a eukaryotic cell because it has a nucleus that encloses the DNA and separates it from the other organelles

An amoeba is a eukaryotic cell because it has a nucleus that encloses the DNA and separates it from the other organelles.

Question 98: Which type of symbiotic relationship benefits one organism while the other is unaffected?
