Study Notes
Movement of Molecules
- Molecules move from areas of high concentration to low concentration.
- This process is called diffusion.
- Osmosis is the movement of water across a selectively permeable membrane.
- Active transport moves molecules against their concentration gradient.
Experiments
- A good experiment yields a correct result and allows testing of hypotheses.
- Hypotheses can be confirmed with certainty through experiments.
Lipase Enzymes
- Lipase enzymes break down lipids.
Ratios of Elements in Formulas
- Empirical formulas show the simplest whole-number ratio of elements in a compound.
- Molecular formulas show the actual number of each type of atom in a molecule.
Chemical Formulas
- NaCl is the formula for sodium chloride (table salt).
- Glucose and sugar are different names for the same substance.
Rest and Motion
- Rest and motion are states that are relative to an observer. This means rest or motion are not absolute concepts.
Cellular Respiration
- Cellular respiration primarily occurs in the mitochondria and cytoplasm of cells.
Species Extinction
- A species is considered extinct when the last individual dies.
Plasma
- Plasma is a good conductor.
Heat Transfer
- Convection is heat transfer due to the actual movement of the medium particles (liquids and gases).
Energy
- Kinetic energy is the energy of motion.
- Potential energy is the energy of position.
Heat Transfer Methods
- The process of heat transfer by the actual movement of medium particles is called convection.
Units
- The SI unit of distance is the meter.
Insulation
- Air is the best material for insulation. Fiber glass is also a good insulator.
Acceleration
- Acceleration is positive when the velocity of an object is increasing.
Human Eye Resolution
- The resolution of the human eye is 0.1 millimeter.
Methods of Heat Transmission
- There are three basic methods of heat transfer: conduction, convection, and radiation.
Photosynthesis
- Photosynthesis is an anabolic process.
Viruses
- Viruses are not classified in any kingdom because they are not considered organisms.
Change in Position
- A change in an object's position is referred to as displacement.
Endangered Species
- An endangered species is one in which the last member of that particular species dies, hence is considered extinct.
Uniform Motion in a Circle
- If a car moves in a circle with a uniform speed, its velocity is variable.
Methods of Heat Transfer
- There are three basic methods of heat transfer: conduction, convection, and radiation.
Density Unit
- The unit of density is kilograms per cubic meter (kg/m³).
Temperature Measurement
- Meteorologists use thermometers to measure air temperature.
Energy
- Energy possessed by a body due to its motion is called kinetic energy.
Elasticity
- A solid object is elastic below the elastic limit.
Earth's Atmosphere
- Earth's atmosphere is held in place by gravity.
Human Scientific Name
- The scientific name of a human being is Homo sapiens.
Weather
- Stormy weather is associated with dark clouds, rain, and thunder.
Acceleration
- Uniform velocity means zero acceleration.
Slope of a Velocity-Time Graph
- The slope of a velocity-time graph represents acceleration.
Organization of Cells
- Cells performing similar functions group together into tissues.
Binomial Nomenclature
- The second word in binomial nomenclature is species.
Effusion
- Effusion is the leaking of a gas through a small hole.
Forces
- Work is the product of force and distance.
Forces Acting on a Falling Object
- Both Earth and the mango attract each other.
Work Conditions
- For work to be done, one condition must be satisfied: force must move over a distance.
Physics Topics
- Study of motion is called mechanics.
Compound Elements
- NaCl (sodium chloride) is a compound composed of sodium and chlorine.
States of Matter
- An ionic state of matter is plasma.
Sharing of Electrons
- Double covalent bonds are formed by sharing two pairs of electrons between atoms.
