Which of the following are the two major parts of the nervous system?  

A. Autonomic nervous system and somatic nervous system.

B. Peripheral nervous system and somatic nervous system

C. Peripheral nervous system and central nervous system.

D. Autonomic nervous system and central nervous system.

Answer Explanation:

The two major parts of the nervous system are the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).

The CNS is made up of the brain and spinal cord and acts as the integration and command center of the body.

The PNS represents the conduit between the CNS and the body and is further subdivided into the somatic nervous system (SNS) and the autonomic nervous system (ANS).

 

Choice A is incorrect because it only mentions two subdivisions of the PNS, which are the autonomic nervous system (ANS) and somatic nervous system (SNS).

Choice B is incorrect because it only mentions one major part of the nervous system, which is the PNS, and one subdivision of it, which is the SNS.

Choice D is incorrect because it only mentions one major part of the nervous system, which is the CNS, and one subdivision of the PNS, which is the ANS.

Therefore, the Correct Answer is C.

  • Q #1: To separate genomic DNA fragments by size, which of these laboratory methods is most useful?

    A. Titration

    B. Electrophoresis

    C. Filtration

    D. Spectrophotometry

    Answer Explanation

    Electrophoresis is the most useful laboratory method for separating genomic DNA fragments by size.

    Electrophoresis is a technique that uses an electric field to separate charged molecules, such as DNA fragments, based on their size and charge.

     

    Choice A is not correct because titration is a laboratory method used to determine the concentration of a solution.

    Choice C is not correct because filtration is a laboratory method used to separate solids from liquids.

    Choice D is not correct because spectrophotometry is a laboratory method used to measure the absorbance of light by a solution.

  • Q #2: The measurement indicated by the line across the center of the cell is best referred to as which of the following?

    A. Area.

    B. Diameter.

    C. Volume.

    D. Radius.

    Answer Explanation

    Diameter.

    The diameter is the measurement of a straight line passing through the center of a circle and connecting two points on its circumference.

    In this case, the line across the center of the cell represents the diameter of the cell.

     

    Choice A, Area, is not the correct answer because area refers to the amount of space inside a two-dimensional shape.

    Choice C, Volume, is not the correct answer because volume refers to the amount of space occupied by a three-dimensional object.

    Choice D, Radius, is not the correct answer because radius refers to the distance from the center of a circle to its circumference and is half the length of the diameter.

  • Q #3: Which of the following is correct regarding the pH scale?

    A. A substance with a pH of 3 is two times more alkaline than a substance with a pH of 4

    B. A substance with a pH of 3 is two times more acidic than a substance with a pH of 4

    C. A substance with a pH of 3 is 10 times more acidic than a substance with a pH of 4

    D. A substance with a pH of 3 is 10 times more alkaline than a substance with a pH of 4

    Answer Explanation

    The pH scale is a logarithmic scale that measures the acidity or alkalinity of a solution.

    A solution with a pH of 7 is neutral, while a solution with a pH less than 7 is acidic and a solution with a pH greater than 7 is alkaline.

    Because the pH scale is logarithmic, each whole number change in pH represents a tenfold change in acidity or alkalinity.

    Therefore, a substance with a pH of 3 is 10 times more acidic than a substance with a pH of 4.

    Choice A.

    A substance with a pH of 3 is two times more alkaline than a substance with a pH of 4 is not correct because it incorrectly states that the substance with a lower pH is more alkaline and also incorrectly states the magnitude of the difference in acidity or alkalinity.

    Choice B.

    A substance with a pH of 3 is two times more acidic than a substance with a pH of 4 is not correct because it correctly states that the substance with a lower pH is more acidic but incorrectly states the magnitude of the difference in acidity.

    Choice D.

    A substance with a pH of 3 is 10 times more alkaline than a substance with a pH of 4 is not correct because it incorrectly states that the substance with a lower pH is more alkaline.
