Study Notes

Classification of Living Beings

Five-Kingdom Classification: Monera (single-celled, no nucleus, e.g., bacteria), Protista (single-celled, with nucleus, e.g., amoeba), Fungi (decompose, chitin cell walls, e.g., mushrooms), Plantae (photosynthesis, e.g., trees), Animalia (depend on other organisms, e.g., humans).
Plantae Kingdom: Bryophyta (non-vascular, e.g., mosses), Pteridophyta (vascular, no seeds, e.g., ferns), Gymnosperms (seeds, uncovered, e.g., pine trees), Angiosperms (seeds inside fruit, e.g., roses).
Animalia Kingdom: Porifera (simple pores, e.g., sponges), Cnidaria (stinging cells, e.g., jellyfish), Arthropoda (jointed legs, e.g., insects), Vertebrata (backbone): Pisces (fish), Amphibia (land & water, e.g., frogs), Reptilia (cold-blooded, scales, e.g., snakes), Aves (feathers, beaks, e.g., eagles), Mammalia (fur, mammary glands, e.g., humans).
Classification and Evolution: Organisms grouped by shared traits that reveal evolutionary relationships from common ancestors.

Life Cycle and Cell Division

Honey Bee Life Cycle: Egg → Larva (fed) → Pupa (develops) → Adult (queen, worker, drone). Uses: Pollination, honey, ecosystem balance.
Cell Division: Mitosis (identical cells, growth, repair, asexual reproduction, phases: prophase, metaphase, anaphase, telophase, cytokinesis), Meiosis (unique cells, reproduction, genetic diversity, two divisions).
Mitosis vs. Meiosis: Mitosis = 1 division, identical cells; Meiosis = 2 divisions, unique cells.
Chromosomes: DNA (genetic info, double-stranded), RNA (helps make proteins, single-stranded), Chromosomes (thread-like DNA carriers), Sex Chromosomes (X & Y determine sex).

Heredity

Mendel's Laws: Dominance (one trait masks another), Segregation (genes separate), Monohybrid Crosses (one trait, F1-all dominant, F2-3:1 ratio).
Dominant & Recessive Traits: Dominant (appears, e.g., tall), Recessive (hidden, unless paired, e.g., short).

Genetic Technology

DNA Testing: Identifying people, finding conditions, solving crimes, CRISPR (gene editing), AI.
Seed Selection: Traditional (hand-picking), Advanced (hybrids, GMO-better crops).
Cross-Breeding: Stronger crops, pest resistance, but can reduce biodiversity.
Artificial Insemination: Sperm to female, IVF (egg fertilization outside body).

Human Blood Circulatory System

Blood: Plasma, red/white blood cells, platelets. Role: Carries oxygen, fights infection, clotting.
Heart: Four chambers (2 atria, 2 ventricles), valves (one-way blood flow).
Blood Vessels: Arteries (oxygen-rich), Veins (oxygen-poor), Capillaries (gas/nutrient exchange).
Blood Circulation: Pulmonary (heart-lungs), Systemic (heart-body).
Blood Groups: A, B, AB, O. Universal donor (O), Universal recipient (AB).
Blood Pressure: Normal is 120/80 mmHg, Uric Acid: Too much can cause gout, manage with diet.

Nature and Environment

Climate Change: Causes (greenhouse gases, deforestation, factories), Effects (higher temps, extreme weather), Solutions (trees, renewable energy, emissions reduction).
Endangered Species in Nepal: Red panda, snow leopard, one-horned rhino. Protection: Preserve habitat, stop poaching.
Herbal Medicines: Holy basil (colds), aloe vera (burns), neem (antibacterial), use: safe, eco-friendly remedies.
