Answer:
myofibril bulbous end of axon and skeletal muscles fibres.
Explanation:o
It represents the chemical synapse of the axon bulbous ends of the motor neuron ( motor end plate) and the skeletal Muscle fibres.
The influx of calcium ions into the bulbous ends leads to the fusion and empty of the vesicles containing neurotransmitters into the synaptic cleft.
The Neurotransmitters binds to the receptors on the muscles membrane to allow the transmission of action potential ( PSIP or PSEP)across the synaptic gap to the muscles fibers to initiate their contraction or relaxation.
The True statements are.
Organisms in a population must compete for the resources as the resources are limited and the organism that compete and survives wins.
The best equipped organism survive which is known as the survival of the fittest.
Over the time due to challenges in the environment the beneficial variation takes place in the organisms and it spreads through the generations and then it gradually changes the whole population.
The false statement is Organism of the same species are equipped with the same survival skills.
The organism of the same species have some variation and because of this variation they compete and win against the other member of the same species.

Explanation:
The last region where sharks live is the Temperate region. These waters are a mix between the frigid polar and the warm tropical water temperatures. The average temperature range for these Temperate regions is around 10º-21º C (50º-69.8º F).
