You experimentally apply a toxin to a muscle and find that it does not contract when you electrically stimulate the motor neuron
Furkat [3]

The question provided is not complete as it lacks the group of choices, however the group of choices are given as follows:

A. A contraction fails to occur because an action potential is not generated in the muscle cell.

B. A contraction fails to occur because this toxin directly prevents ion release from intracellular stores.

C. A contraction fails to occur because neurotransmitter release by the motor neuron is blocked at the neuromuscular junction.

D. A contraction fails to occur because this toxin prevents cross bridge formation and thereby directly prevents contraction.

E. C and D are both true

Answer:

The correct answer is option A : A contraction fails to occur because an action potential is not generated in the muscle cell.

Explanation:

A muscle contraction takes place when action potential bring to muscles by nerves, which is traveled with the help of motor neuron and imitated the muscle contraction.

Acetylcholine or Ach is a chemical messenger to bring the nerve impulses between a nerve and a muscle. If the receptor is block with applying toxin muscle will not contract as ACh will not be able to propagate the nerve impulse to the muscle so there will be no action potential.

The correct answer is option A : A contraction fails to occur because an action potential is not generated in the muscle cell.

In which type of front is the flow of air on both sides of the front almost parallel to the line of the front?
lisabon 2012 [21]

Answer: the answer is B which is stationary

Explanation:

This type of front behaves like a warm front only that it is quiescent because the front barely shifts its position. The weather may also be similar to that of a warm front. The two abutting air masses run almost parallel to the front because none is stronger than the other to cause displacement.
