Well for one the Oceans food chain starts with the sun and then microscopic organisms such as phytoplankton, and if they were destroyed the fish and other small creatures would eventually die off and then larger animals would too. Then that could lead to not much sea life, or sea food left for other people and animals
Answer:
NH3 and HCl
Explanation:
NH3 and HCl are acids because of their hydrogen ions. NHO3 and NaOH are bases (you can tell because they have an OH). I don't believe SCl2 is an acid or a base
Answer: Option (d) is the correct answer.
Explanation:
A reaction in which there occurs change in oxidation state of reacting species is known as an oxidation-reduction reaction.
(a)
Will be written as:

In this reaction, there occurs no change in oxidation state of reacting species. Hence, it is not an oxidation-reduction reaction.
(b) 
Will be written as:

Similarly here, there occurs no change in oxidation state of reacting species. Hence, it is not an oxidation-reduction reaction.
(c) 
Will be written as:

Here, also there occurs no change in oxidation state of reacting species. Hence, it is not an oxidation-reduction reaction.
(d) 
So, here there occurs change in oxidation state of Mg from 0 to +2 and oxidation state of H changes from +1 to 0. Hence, it is an oxidation-reduction reaction.
Thus, we can conclude that
is an oxidation-reduction reaction.

Alfred Wagner's evidence began at the simplest form that the continents appeared to<em> fit</em> together like pieces to a puzzle. It wasn't only that though. The evidence showed that the same rocks and fossils existed on separate continents - the same continents that if pieced together would be connected.
