Study Notes
Climate Factors
- Longitude does not directly affect climate; it primarily determines time zones.
- Climate is influenced by altitude and latitude.
Eye Conditions
- Nearsightedness (Myopia): Distant objects appear blurry; corrected with glasses, contacts, or surgery.
- Farsightedness (Hyperopia): Close objects appear blurry; corrected with glasses or contacts.
Mirrors
- Convex Mirrors: Curve outward; reflective surface faces outward; light rays diverge after reflection.
Systems Interaction: Circulatory and Respiratory
- The circulatory system carries oxygen and nutrients to cells.
- The respiratory system provides blood with oxygen and removes carbon dioxide.
- These systems work together to maintain oxygenated blood flow.
Body Organs
- Esophagus: Muscular tube connecting throat to stomach.
- Liver: Located below the diaphragm; processes toxins; produces bile; stores glycogen.
Environmental Impact of Gases
- Carbon Dioxide (CO2) and Methane (CH4): Greenhouse gases trapping heat, causing global warming and climate change.
Elements and Ions
- Sodium (Na): Atomic diagram shows one valence electron.
- Sodium Ion (Na⁺): Forms by losing the valence electron, acquiring a positive charge.
Chemical Reactions
-
Acid-Base Reaction (Neutralization):
- Acid (HCl) + Base (NaOH) → Salt (NaCl) + Water (H₂O)
Mixtures of Acids and Bases
- Mixing an acid (e.g., HCl) and a base (e.g., NaOH) results in a neutralization reaction producing salt (e.g., NaCl) and water (H₂O).
Plant Tissues
- Xylem: Transports water and minerals from roots to leaves.
- Phloem: Transports sugars and other nutrients from leaves to other parts of the plant.
Plant Support
- Roots: Anchor the plant in soil, providing stability.
- Stem: Supports the plant and allows it to stand upright.
