General Science Mock Test | BPSC

Q1. The study of how genes and their products interact to form complex biological systems is called:

Genomics Transcriptomics Systems genomics Pharmacogenomics

Q2. What is the term for the process of losing electrons?

Reduction Oxidation Ionization Dissociation

Q3. Which of the following is an example of a liquid-liquid solution?

Saline solution Vinegar (acetic acid in water) Air Brass

Q4. A radioactive nucleus emits a beta-minus particle. This means that:

A neutron has converted into a proton, emitting an electron and an antineutrino. A proton has converted into a neutron, emitting a positron and a neutrino. An electron has been ejected from the atomic shell. A high-energy photon has been emitted.

Q5. Electrons orbit the nucleus in specific energy levels called:

Orbits Shells Bands Zones

Q6. According to Bronsted-Lowry theory, a base is a substance that:

Donates a proton (H+) Accepts a proton (H+) Donates an electron pair Accepts an electron pair

Q7. Which of the following authors is known for their work on the Dust Bowl and its environmental impact?

Henry David Thoreau Rachel Carson John Steinbeck Aldo Leopold

Q8. The process of dissolving an ionic compound in a polar solvent like water involves overcoming the electrostatic forces holding the ions together in the crystal lattice and the interaction between the ions and solvent molecules. This energy change is known as:

Enthalpy of hydration Enthalpy of lattice dissociation Enthalpy of solution Enthalpy of solvation

Q9. Which gas is responsible for the 'bad' ozone in the troposphere?

Ozone (O3) Nitrogen Dioxide (NO2) Sulphur Dioxide (SO2) Carbon Monoxide (CO)

Q10. What is the term for a chemical that can spontaneously combust in air?

Pyrophoric Flammable Corrosive Oxidizer

Q11. Epithelial cells that are flat and scale-like are called:

Cuboidal Columnar Squamous Transitional

Q12. The self-assembly of proteins into functional structures is crucial for cellular organization. During the formation of muscle fibers, the precise arrangement of actin and myosin filaments is mediated by a complex interplay of structural proteins and their binding partners. Which protein is known to bind to actin filaments and play a role in their organization into sarcomeres?

Myosin Tropomyosin Nebulin Titin

Q13. The term 'sound insulation' in building design refers to:

Increasing the loudness of sounds within a room Reducing the transmission of sound between spaces Creating a more reverberant acoustic environment Allowing sound to pass through easily

Q14. Which atomic orbital has the lowest energy in a multi-electron atom?

2p 3s 1s 2s

Q15. In the context of BPSC's drug discovery efforts, if you are performing quantitative structure-activity relationship (QSAR) modeling, which validation technique is crucial for assessing the predictive power of the model on unseen chemical compounds?

Internal cross-validation External validation Y-scrambling R-squared calculation

Q16. The joint between the humerus and the radius/ulna is called the:

Hip joint Shoulder joint Elbow joint Knee joint

Q17. What happens to circularly polarized light when it passes through a Nicol prism?

It remains circularly polarized It becomes linearly polarized It becomes elliptically polarized It becomes unpolarized

Q18. The analysis of 'environmental risk assessment' often involves probabilistic modeling. Which of the following challenges is most inherent in modeling environmental risks associated with emerging contaminants?

The absence of established regulatory standards. The limited understanding of exposure pathways and dose-response relationships. The high cost of laboratory testing. The political influence of industry stakeholders.

Q19. The study of pathogen-host co-evolution in biological anthropology highlights how:

Human immune system genes are static and unaffected by historical epidemics. Pathogen virulence is always highest when transmission rates are highest. Host adaptations (e.g., genetic resistance) and pathogen adaptations (e.g., immune evasion) exert reciprocal selective pressures. Cultural practices have no impact on disease transmission patterns.

Q20. Which of the following is a consequence of increased atmospheric CO2 concentration, leading to a feedback loop that exacerbates global warming?

Increased ocean alkalinity due to enhanced CO2 absorption Stimulation of phytoplankton blooms that absorb more CO2 Reduced terrestrial photosynthesis due to stomatal closure Melting of permafrost releasing potent greenhouse gases like methane
