a. sarcoplasmic reticulum ; sarcolemma
b. sarcoplasmic reticulum ; sarcoplasm
c. sarcoplasm ; sarcoplasmic reticulum
d. sarcoplasm ; sarcolemma
e. sarcolemma ; sarcoplasm

B. sarcoplasmic reticulum ; sarcoplasm

Explanation:

A neural signal is the electrical trigger for calcium release from sarcoplasmic reticulum into the sarcoplasm. Electrical signals, called action potentials, travel along the neuron's axon connecting to individual muscle fibers at a neuromuscular junction. Neuron action potentials cause the release of neurotransmitters from the synaptic terminal into the synaptic cleft, where they can diffuse across the synaptic cleft and bind to a receptor molecule on the motor end plate.

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.
