what is an example of newton's third law?
an inflated balloon moves through the air when a jet of air leaves its neck as it
deflates
digestive system
salivary glands - produce saliva to get food down esophagus
esophagus - passageway for food
stomach - uses gastric acid and enzymes to break down food even more
pancreas - creates enzymes that stomach uses
, small intestine - long, absorption of nutrients into body takes place here
large intestine - waste is collected
rectum - waste is released
left ventricle
pumps oxygen rich blood out to other parts of the body
What is the lifecycle of a frog?
1. egg
2. tadpole (polywog) - gills and tail
3. tadpole with legs - back legs first then front
4. froglet - converts to breathing air, crawls onto land
5. adult frog - no tail
how would you date a moon rock?
, by the ratio of radioactive potassium to argon
(based on the amount of radioactive material left)
barometric pressure
use it to predict weather
low pressure generates storms
how much of the moon is lighted during the first and third quarter?
half
what is mitosis?
cell division - creates diploid cells
angle bisector
