NEET Physics and Measurement Mock Test 2025 – Chapterwise Online Practice & Solutions

Thorough practice of the Biology And Human Welfare Mock Test is a smart strategy for NEET 2025-26 aspirants aiming for top scores in Botany. This dedicated chapterwise mock test is curated to match the NTA exam pattern, ensuring you master every important concept—ranging from human health, disease-causing pathogens, and immunity, to microbes in agriculture, industrial use, and government health initiatives. By targeting time-bound MCQs and revising with detailed explanations, you build the speed and accuracy essential for competitive edge in NEET Biology.

Chapter Scope: NEET Biology And Human Welfare – Key Concepts & MCQ Types

The ‘Biology and Human Welfare’ chapter contributes significantly to the Botany section in NEET, often featuring application-based and fact-recall questions. Understanding core ideas from NCERT—such as uses of microbes in health and industry, mechanisms of disease transmission, immunity types, vaccination, and biofertiliser use—forms the foundation. Familiarity with recent NEET trends is vital, as assertion-reason, matching-type, and real-world scenario MCQs are increasingly common.

Syllabus Coverage: Subtopics and High-Yield Focus Areas

• Microbes in Human Welfare: Industrial roles (fermentation, biogas, antibiotics), biofertilisers, biocontrol agents
• Human Health and Diseases: Pathogens (bacteria, viruses, protozoa), transmission, prevention, drug resistance
• Immunity and Vaccines: Types (innate, acquired, active, passive), antibody classes (IgA, IgG), vaccination programs
• Strategies for Enhancement of Food Production: Dairy, apiculture, aquaculture, plant & animal breeding
• Health Initiatives: National and international programs, awareness campaigns, infection control

Biology And Human Welfare: Scoring Strategy & NEET 2025-26 Insights

This chapter typically yields 5–7 marks in NEET, with a balance of straightforward conceptual MCQs and advanced application-based questions. Success comes from fast fact recall, strong conceptual understanding, and targeted revision of NCERT lines and diagrams. Recent NEETs have featured assertion-reason on immunity, case studies of foodborne illness outbreaks, and matching antibodies to their roles.

Formulas, Pathways & Standard Classifications

• Immunity Formula: Adaptive Immunity = Active (Natural + Artificial) + Passive (Natural + Artificial)
  Know examples: vaccination (artificial active), maternal antibodies (natural passive)
• Antibody Classes:
  • IgA – mucosal surfaces
  • IgG – predominant, crosses placenta
  • IgM – first response
  • IgE – allergy, parasitic infections
• Microbial Applications Table:
  • Saccharomyces cerevisiae – fermentation
  • Rhizobium, Azotobacter – biofertilisation
  • Monascus purpureus – statin (cholesterol-lowering agent)
  • Bacillus thuringiensis – biopesticide (Bt crops)

Time Management & Analysis Tips for this Chapter

• Maintain average less than 70 seconds per MCQ in practice; simulate NEET exam conditions.
• Use the on-screen timer when practicing; track which subtopics slow you down.
• Review and reattempt incorrect MCQs to master typical errors and manage negative marking.
• Pay close attention to tricky “EXCEPT/NOT” MCQs, as these are common in Human Welfare.

Common Traps & Mistakes in Biology And Human Welfare MCQs

• Confusing vaccine types (live, inactivated, toxoid) – always check NCERT tables
• Misidentifying microbe roles (e.g., which is a biopesticide vs. biofertilizer)
• Missing out on assertion-reason logic (Beware: both Statement and Reason must be true, and Reason must explain Statement for full marks)
• Not revising government program years or flagship health initiatives
• Overlooking multi-step processes (e.g., fermentation steps, hybrid crop development)

Smart Revision Plan: Last-Minute NEET Chapter Tactics

1. Revisit all NCERT “in-box” MCQs and diagrams—these are frequently NEET-sourced.
2. Practice this mock test under timed conditions: focus on speed and accuracy for every question set.
3. Review answer explanations, especially for application-based and assertion-reason MCQs.
4. Track performance analytics to spot recurring mistakes by subtopic.
5. After each attempt, list top 5 weak concepts and revise those before your next session.

Must-Know Points: Exam-High Yield for Biology And Human Welfare

• Industrial uses of microbes (ethanol, antibiotics, organic acids) – remember examples for direct MCQs.
• Bacterial, viral, protozoan disease agents and their vectors.
• Immunity: active vs passive, vaccine mechanism, and use cases.
• Details of food production strategies—hybrid breeding, animal husbandry, aquaculture terms.
• Names and years of flagship national health programs (often asked as factual MCQs).
