I think it is B. biome
Because biome means a large area dominated by characteristic plants and animals, such as a rain forest, desert, or tundra.
Answer:
Generation of an action potential in the neuron.
Stimulation of Ca2+ entry into the neuron
Release of acetylcholine into the synapse
Depolarization of the muscle fiber membrane
Explanation:
The following events takes place in the vertebrate neuromuscular junction
a) Nerve Action Potential - Action potential reaches the axon terminal
b) Entry of calcium ion - The calcium ion reaches the axon terminal and enter into the presynaptic terminus after which the Synaptic vesicles fuse with the membrane of axon terminal
c) Releasing of Arch Quanta - Acetylcholine is released into synaptic cleft which then binds to the receptor sites on motor end plate
d) The Na+/K+ channels opens and Motor end plate becomes depolarized.

Answer:
Los gases que tienen huellas de carbono son dióxido de carbono, monóxido de carbono y gases de metano, etc.
Explicación:
Los gases contaminados que contienen huellas de carbono son dióxido de carbono, monóxido de carbono y metano, etc. Estos gases tienen un efecto negativo sobre el medio ambiente porque son responsables del calentamiento global de la atmósfera y disminuyen la calidad del aire que produce muchas enfermedades nocivas. Las principales causas de la emisión de gases contaminados son las actividades humanas como la quema de combustibles fósiles y el humo que producen las industrias, etc.
Determined by its primary structure (sequence of amino acids.)
the sequence of amino acids in an protein is determined by the nucleotides in the DNA encoding it
