General Biology

Which one of the following sequence of events is the first to take place during systemic production of protease inhibito

This outcome reflects core biological organization, where structure-function relationships govern cellular processes. Option A captures this correctly because it integrates fundamental principles, consistent with textbook descriptions and experimental observations in general biology.

Ref: Campbell et al., Biology, 11th Edition, Chapter 2, Chemical Basis of Life, discusses fundamental biological principles and molecular organization providing broad foundation for life sciences understanding.

SPECIES INTERACTION

Plants avoiding herbivory by association with unpalatable neighbors is:

Associational resistance occurs when a plant suffers less herbivory because of the identity, abundance, or arrangement of neighboring plants. An unpalatable or chemically defended neighbor may mask host odors, visually conceal the focal plant, repel herbivores, reduce landing probability, or support predators and parasitoids that attack herbivores. The protected plant need not possess the neighbor’s defensive compound; reduced damage emerges from community context. This differs from chemical defense produced by the focal plant itself and from camouflage based solely on matching an abiotic back

Phytohormone ALL PYQS

Salicylic acid is widely used as:

Go with B — Analgesic. Under Phytohormone ALL, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) Growth promoter; C) Ethylene inhibitor; D) Auxin analog. When two options sound similar, choose the one that matches the textbook definition most tightly.

PLANT SEC METABOLITES+PYQS

Flavonoids protect plants mainly from:

Answer: B) UV radiation. For PLANT SEC METABOLITES, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) Herbivores; C) Pathogens; D) Salinity. Name the process first, then pick the option that describes it — don’t reverse cause and effect.
