Science Mtel Flashcards
Nicolas Copernicus
theory that the plants revolving around the sun in the 1500s
Galileo
Improved the telescope
found there were craters on the moon
Francis Bacon
scientific method
- theory - use the theory to make predictions
- predictions - design the experiment to test the prediction
- experiment - preform it
- observation - create or modify the theory
Isaac Newton
Laws of motion
- any object in motion will continue to move in the same direction and speed unless forces act on it
- the greater the mass of an object, the more forceit will take to accelerate the object
- for every action there is an equal or opposite reaction
validity
does the instrument test what its supposed to do?
- criterion
- construct
- content
reliability
does the instrument measure consistently overtime?
- internal consistency
- test/retest
Darwin
theory of evolution by natural selection
engineer design process
- ask
- research
- imagine
- plan
- create
- test
- improve
heart
pumps blood through the rest of your body
lungs
brings oxygen from the air into the body and releases carbon dioxide
kidney
removes waste and toxins. excess water from blood stream, carries out of the body in urine
liver
breaks down and builds up molecules, stores vitamins, destroys old blood cells, destroys poison, and aids in digestion
pancreas
hormones regulates blood glucose levels. neutralizes stomach acid, digest protein
small intestines
absorbs nutrients
large intestines
reabsorbs water + ions - forms and stores feces
pharynx
swallows
esophaugus
transports food
circulatory system
responsible for transporting materials throughout the body. it transports nutriends, water, oxygen. it also carries away waste such as carbon dioxide
(heart blood vessells)
larynax
top of the throat
trachea
connects to the lungs
cellular respiration
bio chemical pathway by which cells release energy from chemical bonds of food molecules and provides energy for the essential processes of life
aerobic cellular respiration
the initial fuel or energy source
glucose –> gylcolysis –> tca cycle –> electrons transport reactions –> ATP (readily usable energy currency for life process
cell membrane
separates the interior of all the cells from the outside environment and protects the cell from its environment
mitochondria
double membrane bound organelle
power house of the cell
responsible for generating most ATP in the cell
