2.1
Anything that has mass (the amount of material in an object) and takes up space
Matter
The smallest unit of an element that can exist and still have the unique characteristics of that element, made of subatomic particles, it is the basic building block of all chemical elements and thus all matter.
Atom
Energy produced from boiling oil, coal, and natural gas, and nuclear energy released when the nuclei of atoms of uranium fuel are split apart are considered what type of energy, renewable or nonrenewable?
Nonrenewable
A _______ is any set of components that function and interact in some regular way.
System
Pink Ladies and Granny Smiths are an example of what?
Apples
Positively charged particles in the nuclei of all atoms which have a relative mass of 1 and a single positive charge.
Protons
Set of components that function and interact in some regular and theoretically predictable manner. Most living systems have inputs, throughputs, and outputs of matter and energy from the environment.
System
What are the three ways in which heat is transferred?
Radiation, Conduction, Convection
What are the three key components of systems?
Inputs, Flows (Throughputs), Outputs
What was the name of the crime boss who was head of the feared Chicago Outfit?
Al Capone
Capacity to do work or to transfer heat between two objects at different temperatures.
Energy
Combination of atoms, or oppositely charged ions, of two or more elements held together by attractive forces called chemical bonds.
Compounds
If you hold a book in your hand, there is _______ energy. If you drop that book on your foot, the _________ energy on the fall transfers to _________ energy because of the motion.
Potential, Potential, Kinetic
A _________ feedback loop causes a system to change further in the same direction.
Positive
What is the only continent with land in all four hemispheres?
Africa
Energy that comes from resources that are replenished by natural processes continually or in a relatively short time.
Renewable Resources
A grouping of genes and associated proteins in plant and animal cells that carry certain types of genetic information.
Chromosome
Flowing water, a car speeding down the highway, electricity, wind is an example of what type of energy?
Kinetic
When a natural system becomes locked into a positive feedback loop, it can reach a:
Tipping Point
Acrophobia is the fear of what?
Heights
Two or more forms of a chemical element that have the same number of protons but different mass numbers because they have different numbers of neutrons in their nuclei.
Isotopes
Threshold level at which an environmental problem causes a fundamental and irreversible shift in the behavior of a system.
Tipping Point
Whenever energy is converted from one form to another in a physical or chemical change, no energy is created or destroyed.
First Law of Thermodynamics
When we get too cold, our brains tell us to shiver, to produce more body heat, to warm up. This is an example of what?
Negative Feedback Loop
