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.

(a) What cell structures best reveal evolutionary unity?
xeze [42]

Answer:

The correct answer will be-

1. Evolutionary unity-  DNA

2. specialized cellular modifications- plant cells have chloroplasts and large central vacuole.

Explanation:

<u>Case I </u>

Evolutionary unity is a concept which explains that all the organisms possess some common structure or universal structure or molecules.

The best characterized evolutionary molecule is DNA molecule which took the role of genetic material in past and is passed on to the daughter cells and still is made up of the same components which are a five-carbon sugar, four types of nitrogenous bases and a phosphate group. This DNA molecule is present in almost every organism except for a few viruses.

<u>Case II </u>

The specialization of the cellular components depends on the function a cell has to perform which became established in the population. The plant cells depended on the sunlight to prepare food for themselves which was done by the chloroplast organelle which is absent in the animal kingdom.
