1.what kind of waves are present during an earthquake?
2.what kind of energy does an unlit match have?
3.which of these is another way to write newton's second law of motion?
4.what is it called when light changes direction after leaving a lens?
5.how do you calculate density?

answer:

1.p-waves and s-waves (which are body waves), and rayleigh waves and love waves

2. the type of energy that an unlit match has is potential energy.

3 . is the pic

4. light doesn't change direction after leaving a lens in a camera. it does change direction in the lens and this is called refraction i believe.

5. divide the mass by the volume in order to get an object's density.

g1

choices:

a. g2. b. g1. c. m

cell division has two checkpoints namely, g1

checkpoint and spindle assembly checkpoint. the checkpoint which determines if

division has properly occurred is the g1 checkpoint. at this point, is a damage

in the dna is detected or  the has not reach the optimum size, the cell is

stopped in g1 and is not allowed to proceed to further process.
