Levels of organization (atom-molecule-cell-tissue-organ-organ-system-organism)
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
