The neurons responsible for connecting the
motor and the sensory neurons are
known as interneurons. They achieve this through creation of neural circuits
which facilitates communication between the motor and sensory nerves. Interneurons also assist in interpretation of
impulses especially those which are found in the brain and spinal cord tissue
The answer is C. Separate into ions
The correct answer is option (B) lemon juice.
pH refers to the logarithmic scale used to indicate the acidity or basicity of an aqueous solution. It is the negative of the base 10 logarithm of the activity of the hydrogen ion. Solutions with a pH less that 7 are considered acidic and the solutions with a pH greater that 7 are considered to be basic. A pH of 7 is neither an acid nor a base and is considered neutral.
An acid has a high concentration of hydrogen ions (H+) and a base has a low concentration of hydrogen ions. Higher the hydrogen ion concentration, pH is acidic. Among the given substances, lemon juice has a pH of 2, urine has a pH of 6, tomato juice has a pH of 4 and black coffee has a pH of 5. Since lemon juice has a pH of 2, it has the lowest –OH ion concentration.
I'm not positive but i believe it would be a ruler with millimeters and centimeters
