<span>Simply because fatty acids, amino acids and nucleic acids are acids that produce hydrogen +. In chemistry definitions, acids are substance that tastes sour that donates hydronium ions in a water solution. An acid is also a compound of substance that produce proton and embrace electrons. A proton according to science is something that has hydrogen but doesn't have electron. That's why when these acids are combined they increase the number of hydrogen + or (H+) in a certain substance.</span>
The three primary systems that make up the human body's movement are the skeletal (articular) system, the muscular system, and the neurological system (central and peripheral).
<h3>What exactly is the nervous system?</h3>
- The control centre of your body is your neurological system.
- It is controlled by your brain and governs your actions, thoughts, and automatic reactions to your environment.
- Additionally, it regulates other bodily functions and systems, including digestion, breathing, and sexual development (puberty).
- The central nervous system's organs are the brain and spinal cord.
<h3>What are the nervous system's functions?</h3>
- Signals are sent from the brain to the rest of the body, including the internal organs, via the nervous system.
- In this way, the nervous system regulates a variety of functions, including the ability to move, breathe, see, and think.

Answer:
The CORRECT ANSWER IS B.
B. Unlike the other countercurrent systems, a countercurrent multiplier system expends energy in active transport.
Explanation:
The countercurrent multiplier system involving the loop of Henle uses up energy in the form of ATP to actively conduct NaCl out of the filtrate in the upper region of the ascending limb of the loop. This energy in the form of ATP that is being used uniquely differentiates a countercurrent multiplier system from the different forms of countercurrent systems.
