Answer is: 4. Sea horse.

Seahorse is species of small marine fishes in the genus Hippocampus.

A seahorse has a bilateral line of symmetry, if it cut along a central axis, the left and right half would be congruent.

In bilateral symmetry or plane symmetry, the sagittal plane divides an organism into roughly mirror image halves.

The formation of ammonia gas involves reacting hydrogen gas and nitrogen gas in a mole ratio of 3 to 1. as shown below:

$N_2 + 3H_2 \rightarrow 2NH_3$

<h3>What is the equation of the formation of ammonia?</h3>

Ammonia gas is formed from the reaction between nitrogen gas and hydrogen gas.

Three moles of hydrogen gas will react with 1 mole of nitrogen gas to form 2 moles of ammonia gas.

The equation of the reaction is given below as:

$N_2 + 3H_2 \rightarrow 2NH_3$

Therefore, the formation of ammonia gas involves reacting hydrogen gas and nitrogen gas in a mole ratio of 3 to 1.
