Rolle's Theorem
Intermediate Value Theorem
Fundamental Theorem of Calculus (Correct answer)
Mean Value Theorem

Correct answer: Fundamental Theorem of Calculus

The Fundamental Theorem of Calculus connects differentiation and integration, stating that a definite integral can be computed using an antiderivative evaluated at the endpoints.

Profit maximization
Utilitarianism
Shareholder theory

Correct answer: Corporate Social Responsibility (CSR)

CSR holds that businesses have obligations to stakeholders including communities, employees, and the environment, not just shareholders.

Question 88: In networking, what does DHCP do?

Routes packets between networks
Encrypts data packets
Translates domain names to IP addresses
Dynamically assigns IP addresses to devices (Correct answer)

Correct answer: Dynamically assigns IP addresses to devices

DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses and other network configuration to devices.

Question 89: What is the greenhouse effect?

The warming of the Earth caused by the reflection of sunlight off ice caps
The process by which atmospheric gases trap heat radiated from Earth's surface (Correct answer)
The cooling effect of aerosols in the atmosphere
The depletion of the ozone layer

Correct answer: The process by which atmospheric gases trap heat radiated from Earth's surface

The greenhouse effect occurs when greenhouse gases (CO₂, CH₄, H₂O vapor, N₂O) absorb and re-emit infrared radiation from Earth's surface, warming the lower atmosphere.

Question 90: Which type of wave requires a medium to travel through?

X-rays
Sound waves (Correct answer)
Light waves
Radio waves

Correct answer: Sound waves

Sound waves are mechanical waves that require a medium (solid, liquid, or gas) to propagate.

Question 91: What is the oxidation state of oxygen in most compounds?

−2 (Correct answer)
0
+2
−1

Correct answer: −2

Oxygen typically has an oxidation state of −2 in most compounds, except in peroxides (−1) and when bonded to fluorine (+2).

Question 92: Which sorting algorithm uses a divide-and-conquer approach and has O(n log n) average performance?

Insertion sort
Merge sort (Correct answer)
Selection sort
Counting sort

Correct answer: Merge sort

Merge sort recursively divides the array in half and merges sorted halves, achieving O(n log n) average and worst-case performance.

Question 93: What does 'accounts receivable' represent on a company's balance sheet?

Cash held in reserve
Money owed TO the company by customers (Correct answer)
Long-term company debt
Money the company owes to suppliers

Correct answer: Money owed TO the company by customers

Accounts receivable is a current asset representing money customers owe the company for goods or services already delivered.

Question 94: The Doppler effect describes what phenomenon?

The change in observed frequency due to relative motion between source and observer (Correct answer)
The bending of waves around obstacles
The interference pattern of two overlapping waves
The reflection of waves off surfaces

Correct answer: The change in observed frequency due to relative motion between source and observer

The Doppler effect is the observed change in frequency (or wavelength) of a wave when the source and observer are moving relative to each other.

Question 95: Which type of bond holds the two strands of a DNA double helix together?

Peptide bonds
Hydrogen bonds (Correct answer)
Covalent bonds
Ionic bonds

Correct answer: Hydrogen bonds

Hydrogen bonds form between complementary base pairs (A-T and G-C) and hold the two strands of the DNA double helix together.

Question 96: Which enzyme is responsible for unwinding the DNA double helix during replication?

Helicase (Correct answer)
DNA polymerase
Ligase
Primase

Correct answer: Helicase

Helicase unwinds and separates the two strands of the DNA double helix by breaking hydrogen bonds between base pairs during replication.

Question 97: What is the term for an organism that breaks down dead organic matter into simpler inorganic compounds?

Apex predator
Producer
Decomposer (Correct answer)
Primary consumer

Correct answer: Decomposer

Decomposers (such as bacteria and fungi) break down dead organic matter into inorganic nutrients, recycling essential elements back into the ecosystem.

Question 98: What is the correct sequence of the scientific classification hierarchy from broadest to most specific?

Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species (Correct answer)
Kingdom, Phylum, Domain, Class, Order, Family, Species, Genus
Domain, Phylum, Kingdom, Class, Family, Order, Genus, Species
Kingdom, Domain, Phylum, Order, Class, Family, Genus, Species

Correct answer: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

The correct Linnaean taxonomic hierarchy from broadest to most specific is Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.

Question 99: In human resources management, 'on-the-job training' differs from 'off-the-job training' because it:

Occurs while the employee performs actual work duties (Correct answer)
Is done only for new hires
Requires external trainers
Costs more money

Correct answer: Occurs while the employee performs actual work duties

On-the-job training occurs in the actual work environment while employees perform their regular job tasks.

Question 100: Which kingdom includes organisms that are eukaryotic, multicellular, and obtain nutrients by absorption?

Fungi (Correct answer)
Protista
Animalia
Plantae

Correct answer: Fungi

Kingdom Fungi includes eukaryotic, multicellular organisms (with some unicellular exceptions) that are heterotrophic and absorb nutrients from their environment.

Question 101: What is the nitrogen cycle's role in ecosystems?

Converting sunlight into chemical energy
Circulating nitrogen from the atmosphere to living organisms and back (Correct answer)
Filtering water through soil layers
Breaking down organic matter into carbon dioxide

Correct answer: Circulating nitrogen from the atmosphere to living organisms and back

The nitrogen cycle describes the movement of nitrogen through the atmosphere, soil, water, and living organisms, making it available for plant growth and protein synthesis.

Question 102: What is the role of ribosomes in the cell?

Lipid digestion
Energy production
Protein synthesis (Correct answer)
DNA replication

Correct answer: Protein synthesis

Ribosomes are the sites of protein synthesis, translating mRNA sequences into polypeptide chains.
