newton's laws of motion
Every action has an equal and opposite reaction
What is newton's third law?
when several species become extinct in a short period of time (like the dinosaurs)
what is a mass extinction?
the four bases in DNA?
what is A, C, T, and G?
speed = distance/time
negatively charged particals
what are electrons
Force equals mass times acceleration (F = MA)
What is newton's second law?
this principle of relative age dating states that layers at the bottom are the oldest
what is superposition?
How do the bases pair in DNA?
a pairs with t and c pairs with g
what is acceleration?
what is the change in an object's velocity? (can be speeding up, slowing down, or changing directions)
what is repel and attract?
what is newtons?
what is precambrian? (the precambrian era lasted 4060 million years and accounts for 88.3% of earth's geologic history.)
RNA has this base instead of thymine
what is uracil?
what affects acceleration?
what is mass and the amount of force applied?
how does an object become positively charged?
what is it loses its electrons?
An object at rest will remain at rest unless acted on by an unbalanced force
What is newton's first law?
this theory states that geologic processes that occur today are the same as those that occured in the past
what is uniformitarianism?
a mistake in DNA is called this
What is a mutation?
the difference between distance and displacement?
what is distance is the total amount covered, and displacement is the length between the starting point and ending point?
how does an object become negatively charged?
what is it gains electrons?
pushing a box is an example of what
what is newton's third law?
the exact age of rocks, in numbers
what is absolute age?
humans have this many chromosomes
what is 46? (23 from mother and 23 from father)
how is velocity different from speed?
what is veloctiy is similar to speed, but with a direction attached
These two subatomic particles cannot leave the nucleus
what is protons and neutrons?
