Biology
What are 4 parts of an animal cell?
Nucleus, cell wall, cell membrane, cytoplasm, mitochondria, vesicles, vacuole
What are the 3 subatomic particles that make up the atom?
Protons, neutrons, electrons
What is reflection?
Reflection is when light bounces off a surface, like a mirror, and comes back to your eyes.
What is the difference between a plant cell and an animal cell?
Animal cells don't have a cell wall or chloroplasts like a plant cell.
What is the Kinetic Molecular Theory?
explains what happens to the three states of matter as they undergo physical changes. All matter is made up of tiny particles. The particles are always moving, have space between them and are attracted to one another.
What is refraction?
Refraction is when light changes direction (bends) as it passes from one material to another, like from air into water.
What are the three statements of Cell Theory?
1. All living things are made up of one or more cells.
2. All new cells come from pre-existing cells.
3. The cell is the basic unit of life.
Describe using Kinetic Molecular Theory how gas particles behave.
Lots of space in between. Moving fast. High kinetic energy. Low attraction to one another.
radio waves, microwaves, infrared rays, visible light, UV rays, X-rays, gamma rays
What is a difference between a Eukaryotic cell and a Prokaryotic cell? Tell me 2 differences.
Eukaryotic: Nucleus, more complex, larger, genetic code in the nucleus, found in plants, animals, and fungi
Prokaryotic: No Nucleus, less complex, smaller, genetic code free floating, found in bacteria
What are the 6 phase changes?
Deposition, Sublimation, Melting, Freezing, Evaporation, Condensation
What is the difference between wavelength, amplitude, and frequency?
Wavelength: distance from one crest of a wave to the next
Amplitude: distance from the center line to the crest of trough of a wave
Frequency: number of complete wavelengths that pass a point in one second as a wave goes by.
What are the 7 characteristics of living things?
1. Living things produce and eliminate waste
2. Living things reproduce
3. Living things grow
4. Living things respond to stimuli
5. Living things take in nutrients
6. Living things need and use energy
7. Living things are made up of cells
What is the Law of Conservation of Mass?
Describes what happens in a chemical reaction to the reactants and the products. It states that the mass of the products is always equal to the mass of the reactants.
How does light behave? (In which 2 ways)
Travels in straight lines.
Light has wave-like properties.
