Answer:
Option A
Explanation:
Prokaryotic cells do not have specialized tasks because they are mostly unicellular (in rare cases multicellular) and don't have a nucleus.
Triggering of the muscle action potential occurs after Ach binds to chemically gated channels in the motor end plate membrane. Acetylcholine (Ach) is a neurotransmitter produced by nerve cells.
An action potential is an electrical signal that travels along the cell membrane as a wave.
This action potential (muscle action potential) drives the contraction of muscle fibers.
When the action potential reaches the neuromuscular junction (i.e., the motor end-plate), acetylcholine (Ach) is released into the synaptic cleft.
Subsequently, Ach can bind and open specific channels localized on the surface of the muscle cells, thereby depolarizing them and triggering muscle contraction.

Answer:
co-dom: both traits show without either completely masking each other: red flower x white flower = pink offspring.
incomplete: both traits show but dont mask: red x white = red and white flower
simple: one dominant trait masks the recessive trait, red x white (where red is dominant) = primarily red flowers (depending on if the flowers are heterozygous or homozygous there will be a different number of red flowers, with a minimum of 2/4).
