Acid

0-6.9 on the pH scale, donates a proton

Biome

A region of the earth's surface with a specific climate where only certain types of plants and animals live. Ex. Tundra

Organism

A single living thing that has all of the characteristics of life. Ex. Dog

Organelle

A small part inside a cell that has a specific job to do. Ex. vacuole

Levels of Biological organization from largest to smallest

Biosphere, Biome, Ecosystem, Community, Population, Organism, Organ System, Organ, Tissue, Cell, Organelle, Molecule, Atom

Matter

Any object that takes up space and has mass

Levels of Biological organization from smallest to largest

Atom, Molecule, Organelle, Cell, Tissue, Organ, Organ System, Organism, Population, Community, Ecosystem, Biome, Biosphere

pH is what?

Hydrogen Ion Concentration

Lipids

Hydrophobic, fats oils and waxes, long term energy

Molecule

Two or more atoms bonded together. Ex. water

Buffer

a substance which protects us from large changes in pH

Hydrogen Bond

attraction between polar molecules that occurs when a hydrogen (H) atom bound to oxygen, nitrogen or fluorine.

Phospholipids

two hydrophobic fatty acids

Mass

Amount of matter in an object

Base

7.1-14 on the pH scale, accepts a proton

Ionic Bond

A bond in which one or more electrons from one atom are removed and attached to another atom

Covalent Bond

A bond in which one or more pairs of electrons are shared by two atoms

Endergonic

Absorbs Heat

Community

All of the different living things (orgamisms) in the same place at the same time. Ex. The white tail deer, oak tree, and gray squirrels in the forest.

Ecosystem

All of the living things (biotic) and the non-living factors (abiotic) in the same place at the same time. Ex. All of the green algae, sunfish, frogs in the water, along with amount of salt and temp of water.

Carbohydrates

C6,H12,O6 Fuel,

Proteins

Carbon, Hydrogen, Oxygen, Nitrogen, usually Sulfurs, one or more chains of amino acids

CHOPN

Carbon, Hydrogen, Oxygen, Phosphorus, Nitrogen

Organ System

Different organs working together to perform a major process in an organism. Ex. Digestive System

Organ

Different tissues working together to form a structure with a specific function. Ex. heart

Solvent

Dissolves a Solute to form a solution

Solute

Dissolves in a solvent

RNA

Double strand, AGCT nitrogenous bases

NonPolar

Equal Charge

Tissue

Many cells of the same type working together to perform a function. Ex.

Population

Many organisms of the same type (species) in the same place at the same time. Ex. a herd of Caribou

Solution

Mixture of a fluid solvent and a dissolved solute

Polar Molecules

Positive in one side, negative in the other

Enzymes

Proteins that catalyze reactions

Nucleic Acid

RNA or DNA, nitrogen attached to sugar phosphate

Exergonic

Releases heat

DNA

Single Strand, AGCU, sugar is ribose

Cell

The basic unit of structure and function in a living thing. Ex. white blood cell

Biosphere

The part of the earth's surface where living things can be found. Ex. Earth

Atom

The smallest unit of matter that retains all the chemical properties of its respective elements. Proton, Neutron, Electron
