Explanation:
The "fossil record" refers to the placement of fossils throughout the surface layers of the Earth. Older fossils are buried more deeply than younger ones. Scientists use the placement of fossils as a guide for determining when life forms existed, and how they evolved.
Answer:
Reactants: hydrogen and oxygen
Products: water
Explanation:
The reactants are what goes into a reaction, i.e. what is reacting. The products are what is formed. The reactants are usually shown on the left, and the products are usually shown on the right.
We can see in this equation that hydrogen (2H2) is reacting with oxygen (O2) to form water (2H2O). Therefore the reactants are hydrogen and oxygen, and the product is water.
With respect, G0 meaning what?
The attached body form of Cnidarians would be polyp
<span>An amphibian that lacks lungs and breathes entirely through its skin would have to be smaller than an amphibian with lungs so that the small oxygen intake correlates with
the small surface area of the amphibian. This would then allow it to breath efficiently.</span>
