Study Notes
Anaerobic Respiration
- Yeast produces alcohol and carbon dioxide through anaerobic respiration.
Earth Layers
- The crust is the Earth's outer layer composed primarily of solid rock.
Mirrors
- Convex mirrors are used for side view in vehicles, offering a wider view due to the diverging light rays.
Properties of Acids
- Acids have a characteristic sour taste, exemplified by citric acid in lemon juice and acetic acid in vinegar.
Mitochondria Function
- Mitochondria convert glucose into ATP, the primary energy currency of cells, enabling various biological processes.
Measurement Units
- The standard unit of speed is meters per second (m/s).
- The standard unit of measurement for temperature is Celsius.
Material Properties
- Malleability refers to the ability to be shaped or extended, typically seen in iron and aluminum.
- Ductility describes the property of metals to be drawn into thin wires, exemplified by copper.
Matter Concepts
- Volume refers to the amount of space occupied by matter.
- Mass denotes the amount of matter within an object.
- Common properties of matter exclude force; hardness indicates resistance to scratching, while brittleness makes solids easy to break.
- Fluidity refers to liquids' ability to flow.
State Changes
- Phase change is the process of changing states (solid, liquid, gas) due to temperature changes.
- Melting point is the temperature at which a solid begins to melt.
- Freezing turns a liquid into a solid, while evaporation changes a liquid to gas.
- Sublimation involves transitioning from solid to gas, whereas condensation changes gas back into liquid.
- Deposition transforms gaseous materials directly into solid.
Nutrition Classifications
- Photosynthesis is the process by which plants make food.
- Herbivores, like cows and rabbits, eat only plants; carnivores, like lions and tigers, consume only meat; omnivores eat both plants and animals.
Nervous System Reactions
- Reflexes are instant reactions to stimuli.
Parts of the Eye
- The cornea is a transparent covering focusing light; the iris regulates light intake; the pupil is the opening allowing light in.
- The lens is clear and receives light from the pupil; the retina captures light, forming inverted images, while the sclera is the white part surrounding the iris and pupil.
- The optic nerve transmits visual messages to the brain.
Vision Conditions
- Hyperopia is another term for farsightedness; myopia describes nearsightedness where far objects appear blurry.
- Astigmatism results from an irregularly-shaped cornea blurring vision.
Auditory and Olfactory Nerves
- The auditory nerve transmits sound signals, while the olfactory nerve conveys smell signals to the brain.
Skin Anatomy
- The epidermis is the outer skin layer; the dermis lies beneath it.
- Oil glands in the dermis produce sebum for skin lubrication.
- Skin is the largest organ of the body.
Natural Environments
- A habitat is the natural environment where an animal lives and interacts.
Light and Galaxies
- White light is a mixture of colors, forming a rainbow when passing through transparent materials.
- Galaxies vary in size, with the smallest being dwarf spheroidal and the largest giant ellipticals.
- The sun is one of many stars in a galaxy, and astronomers use meters for length.
Cosmic Composition
- Current evidence suggests that a significant portion of the universe's mass is dark matter.
- Jupiter is the largest planet, while Saturn has prominent visible rings.
- Mars's red appearance comes from iron oxide on its surface.
General Knowledge
- It takes about eight minutes for sunlight to reach Earth.
- Covalent bonds involve sharing electrons, whereas ionic bonds involve donating electrons.
Cell Structure
- Cells are primarily classified into prokaryotes and eukaryotes; bacterial cells are prokaryotic and often contain plasmids.
- Tissue is a collection of cells that perform similar functions.
Electromagnetic Waves
- Gamma rays possess the shortest wavelengths among electromagnetic waves.
Brain Function
- The hypothalamus links the nervous and endocrine systems, regulating various body functions.
DNA Structure
- Nucleotides consist of three components: phosphate, nitrogen base, and sugar.
- Genes are hereditary units encoded in DNA or RNA.
Gas Laws
- Charles's Law states that the volume of a gas is directly proportional to its temperature in kelvins under constant pressure.
Geological Events
- A collision between two continental crusts typically results in the formation of mountains and earthquakes.
