Answer:

Motor neuron.

Explanation:

Motor neuron is a nerve impulse that transfer the messages from the central nervous system to the effector organ. The effector organ can be any muscles, gland or tissue.

The ventral root of reflex arc that controls the leg movement is severed, motor neuron pathway blocks the nerve impulse because the information cannot be  transferred from the CNS to the leg.

Thus, the correct answer is option (1).

Lady_Fox [76]

Answer:

The correct answer would be C. The protein synthesized will contain many erroneous amino acids since the loss of one base will shift the reading of the encoded base sequence.

Deletion mutation that does not occur in the multiple of three bases can results in frame-shift mutation.

It changes the reading frame of nucleotide in DNA. Thus, the reading frame of codons in mRNA would also change.

Consequently, the sequence of amino acids in a polypeptide chain would change or alter. Thus, a protein would contain many erroneous amino acids.

An example of the same is shown below in the image.
