Q

Genes

A

Inherited traits

25
Mendelian Genetics
Dominant vs recessive traits
26
Natural Selection
Evolution, adaptation
27
Artificial Selection
Selective breeding of traits by humans.
28
Mutation
Changes in DNA sequence
29
Genotype vs Phenotype
Genetic makeup vs physical traits
30
Alleles
Different versions of a gene
31
Ecosystems
Interactions between organisms and their environment
32
Food Chains & Webs
Energy flow, producers vs consumers.
33
Trophic Levels
Primary producers, consumers, decomposers.
34
Symbiosis
Mutualism: Both benefit. Commensalism: One benefits, other unaffected. Parasitism: One benefits, one harmed.
35
Biomes
Different global ecosystems (deserts, forests, tundras).
36
Biodiversity
Variety of life forms
37
Vertebrates
Animals with a backbone/spinal column. * Fish: Aquatic, gills, cold-blooded. * Amphibians: Live in water & land, moist skin, lay eggs. * Reptiles: Dry scaly skin, lay eggs on land. * Birds: Feathers, lay eggs, warm-blooded. * Mammals: Hair/fur, warm-blooded, give birth to live young, produce milk.
38
Invertebrates
Animals without a backbone. * Arthropods: Insects, spiders, crustaceans (exoskeleton, jointed legs). * Mollusks: Snails, octopuses, clams (soft body, some with shells). * Cnidarians: Jellyfish, corals (stinging cells, radial symmetry). * Echinoderms: Starfish, sea urchins (spiny skin, radial symmetry). * Annelids: Earthworms, leeches (segmented bodies).
39
States of matter
solid, liquid, gas, and plasma
40
Atoms:
Protons (+), Neutrons (0), Electrons (-).
41
Atomic Number
Number of protons, unique to each element.
42
Periodic Table
Elements, groups, and properties.
43
Atomic Bonds
Ionic, Covalent, Metallic.
44
Density
Mass/Volume.
45
Law of Conservation of Mass
Matter cannot be created or destroyed.
46
Oxidation & Reduction
Electron transfer
47
Catalysts
Speed up reactions
48
Newton’s Laws:
* First Law (Inertia): Objects stay in motion/rest unless acted upon. * Second Law: Force = Mass × Acceleration (F=ma). * Third Law: Every action has an equal and opposite reaction.
49
Energy Types
Kinetic, potential, thermal, electrical, nuclear.
50
Work & Power
Work = Force × Distance, Power = Work/Time.
51
Electricity & Magnetism
Circuits, current (AC/DC), resistance
52
Wave Properties
Frequency, wavelength, amplitude. * Reflection: Bouncing off surfaces. * Refraction: Bending through different media. * Diffraction: Bending around objects.
53
Simple Machines:
Lever, pulley, inclined plane, wedge, screw, wheel & axle.
54
Thermodynamics
Heat transfer, laws of thermodynamics
55
Rock Cycle
Igneous, Sedimentary, Metamorphic rocks
56
Plate Tectonics
Earthquakes, volcanoes, continental drift
57
Atmosphere Layers:
* Troposphere: Weather occurs, water vapor, suspended particles. * Stratosphere: Ozone layer, absorbs UV radiation. * Mesosphere: Coldest layer. * Thermosphere: Auroras, satellites. * Exosphere: Outermost layer.
58
Water Cycle
Evaporation, condensation, precipitation
59
extra info
Big Bang Theory: Universe origin, 13.8 billion years ago. Solar System: Planets, moons, asteroids, comets. Stars & Galaxies: Life cycle of stars, black holes. Earth’s Motion: Rotation (day/night), Revolution (seasons). Tides: Moon’s gravitational effect on oceans.
