Biosphree; all of the elements that support lifewater land lower atmosphere madagascar
Ecosystem; all organisms living in a particular area. Forrest in Madagascar
Community- array of organisms. Birds snakes trees. All organisms in the forest
Population- Group of ringtaiiled monkeys , all individuals in a single area
Organism; ring tailed lemur an individual living thing
Organ system- Nervous system ,nervous system controls its actions, organs working together.
Organ- made up of, similar cells that performs a specific function tissue Cell-fundamental unit of life
Organell- membrane enclosed structure that performs a specific function
Molecule- cluster of small chemical units atoms held together by molecular bond
Deoxyribonucleic acid
CH. 2
Matter- anything that occupies space and has mass
Element- a substance that cant be broken down to other substances by ordinary chemical means. 92 elements
Compound-two or more different elements combined in a fixed ratio. More common than lone elements.
Trace elements- in the body only make up about 0.004% of your body weight but vital for energy processing.
Electrons- two revolve on an orbital(discrete volume of space where E are found) around the nucleus at about the speed of light.
Move around the nucleus only at specific energy levels called Electron Shells
Protons + Neutrons = Mass #
The number of eectrons in an atoms outer valence shell determines its overall chemical properties.
Atomic number-the first number (number of protons)
Radioactive isotope- unstable neutrons (14C) decays spontaneously giving off particles and energy.
Medical diagnosis and treatment: Used to tag chemicals that accumulate in the body Phosporous in bones, inject a tracer isotope. PET scanner produces an image of where the radiation
