<span>The most primitive vertebrates whose reproductive pattern includes the amniotic eggs are the reptiles.
An amniotic egg is filled with amniote, which are these membranes that have fluid in them. They serve to protect the embryo and enable it to survive any harsh conditions that may harm it. These cells have protein shells as well as calcium that provide further protection.

Given:
The solution decreased by
ounces every hour for 5 hours.
Remaining solution at the end of the experiment =
ounces.
To find:
The initial amount of solution.
Solution:
Let the initial amount of the solution be x.
The solution decreased by
ounces every hour for 5 hours.
Total decreased amount 

Initial amount = Remining amount + Decreased amount of solution.




Therefore, the initial amount of solution is 18 ounces.
Hmm, we use carbohydrates as our main fuel energy source but we also store energy in lipids.
