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.

Which synapse(s) are specifically responsible for the habituation of the withdrawal response?
fredd [130]

<u>Sensory neuron to motor neuron</u> are specifically responsible for the habituation of the withdrawal response.

  • The withdrawal reflex, which is the automatic withholding of a limb from a painful stimulation, is what is known as this automatic reaction.
  • Humans are shielded by this reflex from tissue necrosis brought on by exposure to noxious stimuli like pain or heat. Either the upper or lower limbs may experience it.
  • A somatic reflex, like the withdrawal reflex, and a visceral reflex, an autonomic reflex, differ in that the latter has an efferent branch.
  • The lower motor neuron in the ventral horn of the spinal cord, which immediately projects to a skeletal muscle to produce its contraction, is the output of a somatic reflex.
