Q1. Which of the following can be a symptom of an invasive plant species' success?

Increased flowering of native plants Dense monocultures of the invasive species Greater variety of native insects Improved soil health
Q2. What is the function of the Golgi apparatus (or Golgi complex)?

Protein synthesis Lipid synthesis Modifying, sorting, and packaging proteins and lipids DNA replication
Q3. Which cestode infects humans primarily through consumption of undercooked fish?

Taenia saginata Diphyllobothrium latum Hymenolepis nana Dipylidium caninum
Q4. The life cycle of Taenia saginata involves humans acting as the:

Intermediate host Definitive host Paratenic host Accidental host
Q5. The time it takes for the plasma concentration of a drug to reduce by half is called:

Steady state Loading dose Half-life Therapeutic window
Q6. In the context of evolutionary genomics, phylogenetic trees are constructed based on:

Protein-protein interaction data DNA or protein sequence similarities and differences Gene expression patterns Epigenetic modification profiles
Q7. A gene pool is:

The study of genes The sum of all alleles in a population A type of mutation The process of natural selection
Q8. The concept of 'umbrella species' in conservation biology is based on the premise that:

Protecting these species will inevitably lead to the protection of many other co-occurring species. These species have a disproportionately large impact on ecosystem functioning. These species are the most charismatic and thus attract the most public support for conservation. These species are the most genetically diverse and thus represent a significant portion of biodiversity.
Q9. The term for programmed cell death, which is important for sculpting tissues and organs, is:

Mitosis Meiosis Apoptosis Fertilization
Q10. What is a virion?

A virus within a host cell An inactive virus A complete, infectious virus particle The genetic material of a virus
Q11. Parasitoids are biological control agents that:

Consume their host Lay eggs in or on their host, eventually killing it Compete with pests for resources Are immune to pest diseases
Q12. Which layer of the adrenal cortex is primarily involved in the synthesis of androgens like dehydroepiandrosterone (DHEAS)?

Zona glomerulosa Zona fasciculata Zona reticularis Adrenal medulla
Q13. Which of the following is a common type of biological data?

Financial reports Weather patterns DNA sequences Traffic flow
Q14. Which of the following is an example of determination in developmental biology?

A cell becoming larger. A cell dividing. A cell committing to a specific developmental fate. A cell migrating.
Q15. Which structure passes through the foramen ovale?

Optic nerve Maxillary nerve Mandibular nerve Ophthalmic nerve
Q16. What is the primary role of Protected Areas in conservation?

To facilitate resource extraction. To safeguard biodiversity and natural ecosystems from harmful human activities. To serve exclusively for scientific research. To encourage tourism development without restrictions.
Q17. A 'genome-scale metabolic model' primarily aims to represent:

The complete gene regulatory network. All known metabolic reactions within an organism. The spatial organization of organelles within a cell. The signaling pathways initiated by external stimuli.
Q18. Who is considered one of the founding fathers of ethology?

Charles Darwin Gregor Mendel Konrad Lorenz James Watson
Q19. The process of a plant bending towards a light source is an example of:

Geotropism Hydrotropism Thigmotropism Phototropism
Q20. The idea that organisms change over time due to the inheritance of acquired characteristics was proposed by:

Charles Darwin Gregor Mendel Jean-Baptiste Lamarck Alfred Russel Wallace
