Small pools of water with ocean life. One day, while walking along the coast, you encounter the area pictured here. You notice that most of the water is gone at low tide and that an abundance of life lives in this area.

To which ocean zone does this area belong?

Intertidal zone (i think)

Explanation:

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.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
