Answer:
I hope this will help you
Explanation:
The air that is inside a ship is much less dense than water. That's what keeps it floating! The average density of the total volume of the ship and everything inside of it (including the air) must be less than the same volume of water.

BCAA supplements are commonly taken to boost muscle growth and enhance exercise performance.
They may also help with weight loss and reducing fatigue after exercise. This article contains all the most important information about branched-chain amino acids and their benefits.
<h3><u>What are purposes of Branched-chain amino acids (bcaas) ?</u></h3>
- Leucine, isoleucine, and valine are the three essential amino acids that make up the branched-chain amino acids (BCAAs).
- Since they are vital, your body cannot create them on its own and you must get them through food.
- BCAA supplements have been demonstrated to increase muscular mass, lessen muscle pain, and reduce muscle fatigue.
- They have also been used successfully in hospitals to lessen liver disease symptoms and stop or slow down muscle loss.
- However, since the majority of people consume enough BCAAs from their diets, taking supplements is unlikely to provide any further advantages.
