Hello there!
I had a question just like this before and I believe there are options to choose. It doesn't matter, I'll work it out.

We can determined that jellyfish existed before trilobites and ammo-nites.
I hope I helped!
Red pandas are going extinct because of habitat destruction. They also reproduce slowly, that's why they're one of the most endangered animals.. :(
potential energy
you have potential energy when you're stopped. you have kinetic energy when you're moving. so as you're going down a hill, kinetic energy is increasing and potential energy is decreasing.
As stated above, breathing is the biological process of inhaling and exhaling of the gases between the cells and the environment. The mechanism of breathing involves various respiratory structures such as the windpipe, lungs and nose. Respiration, on the other hand, is a chemical process that takes place in the cell.
Answer:
pH = 13.70
Explanation:
pH is a value used in chemistry to determine nature of solutions, quality of several chemicals, etc.
pH is defined as -log [H₃O⁺]
A solution with molar concentration of hydronium ion, H₃O⁺. of 2x10⁻¹⁴M, has as pH:
pH = -log [2x10⁻¹⁴M]
pH = 13.70
