|
Homeostasis
|
Maintainance of constant internal conditions in an organism
|
Ex: Temp, blood sugar, acid levels |
|
Qualitative vs Quantitative data
|
Qualitative: Describtions in words of observations
Quantitative: Numeric measurements |
Trick: N for numbers in quantitative |
|
Community
|
Group of different species living in an area
|
|
|
Ecosystem
|
Physical environment with species that interact with others and abiotic factors
|
|
|
Detritivore vs. Decomposer
|
Detritivore: Eats detritus, or dead organic matter
Decomposer: A form of detritivore that breaks down organic matter into simpler compounds |
|
|
Ecological Niche
|
All of the physical, chemical, and biological factors that a species needs to survive, stay healthy, and reproduce
|
|
|
Principle of Competitive Exclusion
|
When 2 species are competing for the same resources, one will better suit the niche, and the other will be forced to another niche or die.
|
(Niche Partitioning) |
|
Biomagnification
|
Process in which a pollutant moves up the food chain as predators eat prey, accumulating a higher concentration in the predators' bodies.
|
|
|
Habitat Fragmentation
|
A barrier forms that prevents an organism from accessing it entire home range
|
Can lead to geographic isolation |
|
Ion
|
An atom that has gained or lost electron(s)
|
|
|
Solution
|
Mixture of substances that is the same throughout.
|
|
|
Solvent
|
Substance that is present in a greater amount and dissolves in another substance.
|
Ex: The KOOL AID when you mix it with water |
|
Solute
|
Substance that dissolves the solvent.
|
Ex: The WATER when you mix in Kool Aid |
|
What does the pH scale measure?
|
A solution's acidity, or hydrogen ion concentration
|
|
|
Carbohydrates: Monomers, polymers, funcion, and name ID
|
M= Monosacharides
P= Polysacharides F= Main source of energy N= Usually ends in -ose |
Ex: Glucose, cellulose |
|
Lipids: Monomers, polymers, funcion, and name ID
|
M= Fatty acids
P= Triglycerides F= Provide energy to cells and are used in parts of a cell's structure N= Usually ends in -ic |
Ex. Palmic acid, Lanolic acid |
|
Proteins: Monomers, polymers, funcion, and name ID
|
M= Amino acids
P= Proteins F= Controls reaction rates, regulates cell processes, forms bone and muscle, transports substances in and out of the cell, and help fight off disease N= Usually ends in -ase |
Ex. Lipase, peptase |
|
Nucleic Acids: Monomers, polymers, funcion, and name ID
|
M= Nucleotides
P= Nucleic acids F= Contain detailed instructions for proteins N= Usually end in -ine |
Ex. Guanine, adenine |
|
Sustainable Development
|
Natural resources are used and managed in a way that meets current needs without hurting future generations
|
Basically, the opposite of what the world is doing now |
|
Cell Theory states that:
|
1) All organisms are made of cells
2) Existing cells are produced by other living things 3) The cell is the most basic unit of life |
|
|
Endoplasmic Reticulum
|
Interconnected network of thin folded membranes where proteins and lipids are produced
|
(ER) |
|
Ribosomes
|
Link amino acids to form proteins
|
Can be located on ER or free-floating |
|
Golgi Apparatus
|
Closely layered stacks of membrance-enclosed spaces that process, sort, and deliver proteins
|
|
|
Endocytosis vs. Exocytosis
|
Endo: Process of taking liquids or large molecules into a cell by engulfing them in a membrane
Exo: Telease of substances out of the cell by fusion of a vesicle with the membrane |
|
|
Adenine Triphosphate
|
Molecule that transfers energy from the breakdown of food
|
(ATP) |
|
Cell Differentiation
|
Unspecialized cells develop into thier mature forms and functions
|
|
|
Somatic cells
|
Body cells, haploids
|
|
|
Gametes

|
|
|
Translation
|
Process that converts an mRNA message into a polypeptide
