Chemistry of Life
Define "matter."
Anything that has mass and takes up space
Define "hypothesis."
Educated guess
Name two "non-contact" forces.
Gravity, Magnetism, Electricity
Proton
Electromagnetic radiation with the shortest wavelength
Gamma rays
What is an "element?"
Substance that consists on only one type of atom
Making observations about the natural world
Name two contact forces.
Normal, Applied, Friction
What is created as a result of mitosis?
Identical daughter cell
Name one type of biodiversity and provide one advantage.
Genetic engineering
Cloning
Artificial selection
Define or describe a scientific theory.
Does not go on to become a scientific law
Newton's 1st Law of Motion?
Inertia
Name two elements that can become magnetic.
Iron, Nickel, Cobalt
What types of materials refract light the most?
Ones with the highest density
Punnett Square: Ff x Ff
Percentage of offspring that are heterogenous
50%
Explain "scientific law" and provide an example.
Observation about the natural world that holds true under certain conditions
Universal gravitation
Conservation of mass
Conservation of energy
Explain Newton's 3rd Law of Motion and provide an example.
Action/Reaction: Answers will vary.
Explain how auroras are created.
What is a "transform boundary" and what geological event occurs at this type of boundary?
Plates slide past one another: earthquake
Part 2: Explain one difference between a prokaryotic cell and a eukaryotic cell
Bacteria
No cell nucleus
Flagella
Genetic material scattered throughout the cell
Lacks organelles
Explain two advantages of a formal scientific experiment using the scientific method.
Cause/effect relationships
Support ( or non-support) of a hypothesis
Easily replicated/repeated
Variables more easily controlled
Part 1: Explain the difference between mass and weight. Part 2: If an object weighs 60 lbs on Earth, what would its approximate weight be on the Moon?
Weight differs as it's affected by the force of gravity.
How are series and parallel circuits different?
Series: All portions of the circuit turn turn on/off at the same time.
Parallel: Parts of the circuit can be activated separately.
Define "divergent boundary" and name a geological event that can happen at this type of boundary.
Separation:
Volcano
Sea floor spreading
