is the method by which scientist use to solve problems
is a possible explanation for a problem
in an experimnet is what is used for comparison in an experiment
are variables that the experimenter changes
change as a result of the independent variable
living things are made of organic compounds
bonds are formed by the sharing of electrons
bonds are formed by the transfer of electrons
Carbohydrates, Lipids, Proteins, and Nucleic Acids
four main organic compounds
are made up of amino acids and function in the building, repairing cells and give you your characteristics
are made of monosaccharides and funtion in providing energy.
are made up of glycerol and fatty acids and function in energy storage and insulation
are made up of nucleotides and carry genetic information
are proteins that speed up chemical reactions
is the basic unit of all living things
functions in controlling activities of the cell
found in plant cells composed of cellulose and adds a layer of protection
provide storage for excess matrerials in a cell. these are larger in plant cells when compared with those in animal cells.
proteins are made/assembled in here
Plasmea (cell) Membrane
maintains homeostaisis in the cell
energy for the cell is produced in here through cellular respiration
are the site where photosynthesis takes place within a cell
cells do not have membrane bound organelles
is the process of maintaining a constant internal enviorment
Diffusion and osmosis are examples of this = transport that does not require energy
requires energy because particles are moving from areas of low concentration to areas of high concentration
is the process of cell division in body cells whereby diploid cells are produced
is the process of cell division in gametes whereby haplod cells are produced
a fertilized egg.
cells have membrane bound organelles Ex. animal or plant cell
the process used to make energy and takes place in the mitochondria
reactants are glucose and oxygen and produces water, carbon dioxide and energy.
does not require oxygen and produces small amounts of energy along with lactic acid or alcohol
is the form of energy in teh cell produced i teh mitochondria
is stored in ATP in teh bonds that hold the phosphates together
is the process that uses carbon dioxide and water to produce glucose and oxygen.
James Watson and Francis Crick
In 1953 they discovered the structure of teh DNA double helix
is made up of a long chain of nucleotides that include a nitrogen base, a phosphate and a sugar
is a change in the DNA code that can lead to a change in protein production
hold the nitrogen bases together of complimentary DNA strands
involves teh copying of a DNA strand
involves the process fo transcription and translation
is the process of producing an mRNA complement of DNA and translation is the 2nd step in protein synthesis where amino acids are connected in teh appropriate order to make a protein
is considered teh Father of Genetics based o his studies of heredity with pea plants
worked with preserving blood in blood banks.
