Back 3

all chemical and engery transformation within the cell.

Front 4

Homeostasis

Back 4

the internal maintence of conditions within a certain range.

Front 5

natural selection

Back 5

certain individuals may inherit a change in their genectics that makes it better suited to its current environment

evolution

Back 6

actual process by which changes occur over time in organisms.

Front 7

adaptation

Back 7

peculicarity of form, function, or behavior that promotes a species existence

Front 8

biodiversity

Back 8

the total number of species and their relative abondance

isotopes

Back 9

have the same number of protons but a different number of neutrons (can meausure age)

Front 10

Ionic Bonding

Back 10

when electrons are ctually transferred

Front 11

Coralent bonding

Back 11

where electrons are shared

Front 12

cell theory

Back 12

all organizimes are composed of cells, cells are the basic unit of both stucture and function, cells only come from pre existing cells.

tonicity

Back 14

relative concentration of solutes in a solutuion

Front 15

Isotonic

Back 15

cell neither gains nor looses water (animal cells)

Front 16

Hypotonic

Back 16

gain water (fresh water)

Front 17

hypertonic

Back 17

lose water( salt water fish)

recieves and processes molecules

Front 36

vacuoles

Back 36

storage structure, large membranous sacs

Front 37

chloraplasts
