I believe the answer is D. Hope this helps ;D
They form under a pressure and heat that doesn't destroy the fossils. Igneous and metamorphic rock form from molten rocks thus reaching a temp that destroys the fossils within.
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.
Hearing loss that occurs as a function of age is called presbycusis.
In presbycusis, the patient will lose the ability to hear the higher frequency of sound.
Anosmia is losing the ability to smell. Presbyopia is vision loss that occurs as a function of age.
