Molecules
Organic molecules that are composed of only carbon and hydrogen
The capacity to do work
Work
Closest to earth and where weather occurs
Troposphere
An animal without a backbone
Invertebrate
A characteristic of a pure substance that describes its ability to change into different substances
Chemical property
Nutrients the body uses to build and maintain its cells and tissues
Proteins
Energy in transit due to a temperature difference between the source from which the energy is coming and a sink toward which the energy is going.
Heat
The cycle through which water in the hydrosphere moves; includes such processes as evaporation, precipitation, and surface and groundwater runoff
Hydrologic cycle
Internal fertilization and development
Reproduction in mammals
A change in the form or appearance of a material that does not change it into a new substance; a change in size, shape, or state of matter; no new matter is formed; ex. melting ice, tearing paper, dissolving kool-aid, mixing salt and pepper, muscles of stomach grind food into smaller pieces
Physical change
Energy-rich organic compounds, such as fats, oils, and waxes, that are made of carbon, hydrogen, and oxygen.
Lipids
1) energy can not be created or destroyed, only converted from one form to another, 2) each time you convert one form of energy to another, some energy is converted to a non-usable form (more energy efficient to consume plants because they exist very close to the initial source of energy)
Laws of Thermodynamics
A body of rock or sediment that stores groundwater and allows the flow of groundwater.
Aquifer
Archaebacteria, Eubacteria, Protista, Fungi, Plantae, Animalia
Kingdoms of life
A theory that states that all matter is composed of tiny particles called atoms.
Compound made up of carbon, hydrogen, and oxygen atoms; major source of energy for the human body
Carbohydrates
Quantity of energy transferred by a force when it is applied to a body and causes that body to move in the direction of the force
Work
The geologic principle that states that in horizontal layers of sedimentary rock, each layer is older than the layer above it and younger than the layer below it.
Law of Superposition
A group of organisms that have jointed appendages, an exoskeleton, bilateral symmetry, and reproduce sexually; insects, arachnids, millipedes and cenitpedes, and crustaceans
Arthopods
A quality or condition of a substance that can be observed or measured without changing the substance's composition
Physical property
Macromolecules containing hydrogen, oxygen, nitrogen, carbon, and phosphorus. DNA and RNA
Nucleic acids
The unit of work
Joule
A systematic approach to physical geography that looks at the interaction between Earth's physical systems and processes on a global scale.
Earth System Science
Father of genetics
Mendel
The inner part of an atom that contains the proton and the neutron is called the
Nucleus
