Life and the Scientific Method
The scientific study of life
What is Biology?
The process of change that has transformed life on earth?
What is evolution?
Anything that occupies space and has mass
What is matter?
Carbon-based molecules that are large and complex
What is an organic compound?
a biological catalyst
What is an enzyme?
A educated guess that can be tested.
What is a hypothesis?
A theory proposed by Charles Darwin, that the traits best suited for an environment are more likely to be passed down which in time will change a population
What is Natural Selection
The smallest unit of matter that still retains the properties of elements
What is an atom?
A giant molecule
What is a macromolecule?
The amount of energy that reactants must absorb before a chemical reaction occurs that an enzyme lowers
What is activation energy?
Bacteria, archaea, eukarya
What are the 3 domains of life?
Comes from selective breeding, commonly seen in livestock, crops, and pets.
What is artificial selection?
An atom that has the same amount of protons, and behave identically in chemical reactions, but have different neutrons.
What is an isotope?
Cells link monomers to form polymers by removing a molecule of water
What is the dehydration reaction?
nonprotein helpers that help activate, many enzymes need these.
What is a cofactor?
a branch of biology that names and arranges species into a hierarchy of broad groups (genus, family, order, class, and phylum)
What is taxonomy?
The physical appearance of a trait
What is a phenotype?
A bond where the atoms transfer their electrons in order to follow the octet rule.
What is an ionic bond?
a large lipid made up of glycerol and fatty acids (triglycerides)
What is fat?
A chemical substance that interferes with an enzymes activity by blocking substrates from entering the activation site
What is a competitive inhibitor?
The 7 properties of life.
What is order, production, growth & development, regulation, energy processing, evolutionary adaptation, response to environment?
What encodes genes?
A sort of bond that is typically seen between water molecules
What is a hydrogen bond?
the precise sequence of amino acids in the polypeptide chain that make proteins
What is primary structure?
The part in the catalytic cycle where the substrate is converted into the products
What is the 3 stage of the catalytic cycle?
