Step 4: Make Initial Observations
Examine the data table, which shows data for quadrat
#18.
Compare the data you recorded in Table A of your
Student Guide with Table A from quadrat #18 in the
control group. Remember that the control group
contains the quadrats without compost.
Quadrat #18
Day 1
The number of blades in your quadrat is
the number of blades in quadrat #18.
The average height of the grass in your quadrat is
the average height of the
grass in quadrat #18.
Number of Blades
Average Height (cm)

Your answer would be A for the first one and B for your second one!!

Explanation:

the same as or b and the same as or b (it's the same thing for both)

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
