Explanation:
Controls senses and most body functions .
Carries message and information between the brain & body
Explanation:
The nervous system helps to control senses, body functions, carries message and information between brain and the body. It consists of the brain, spinal cord and the nerves.
- Using series of electrical nerve impulses, the nervous system controls the body administration.
- The brain, spinal cord and nerves directs communications between different parts of the body system.
- It is divided into two broad categories, the central nervous system which consists of the brain and spinal cord and the peripheral nervous system which is made up the nerves.

Answer:
30 mL VOLUME OF 3.0 M HCl SHOULD BE USED BY THE STUDENT TO MAKE A 1.80 M IN 50 mL OF HCl.
Explanation:
M1 = 3.00 M
M2 = 1.80 M
V2 = 50 .0 mL = 50 /1000 L = 0.05 L
V1 = unknown
In solving this question, we know that number of moles of a solution is equal to the molar concentration multiplied by the volume. To compare two samples, we equate both number of moles and substitute for the required component.
So we use the equation:
M1 V1 = M2 V2
V1 = M2 V2 / M1
V2 = 1.80 * 0.05 / 3.0
V2 = 0.09 /3.0
V2 = 0.03 L or 30 mL
To prepare the sample of 1.80 M HCl in 50.0 mL from a 3.0 M HCl, 30 mL volume should be used.
