Answer:
1. Nerve impulse
2. Neurons
Explanation:
Neurotransmitters are compounds with low molecular weight. They are secreted by axon terminals of the neurons. The released neurotransmitters then bind to the receptors located on next neuron or on the surface of muscle cell.
The function of neurotransmitters is to carry the nerve impulse from presynaptic neuron to the postsynaptic neuron or from neurons to the effector organs such as muscles and glands.
For example, neurotransmitters are released into the synaptic cleft to transmit the nerve impulse between neurons.
In 1929 the American astronomer Edwin Hubble discovered that the distances to far-away galaxies were proportional to their redshifts. Redshift occurs when a light source moves away from its observer: the light's apparent wavelength is stretched via the Doppler effect towards the red part of the spectrum. Hubble’s observation implied that distant galaxies were moving away from us, as the furthest galaxies had the fastest apparent velocities. If galaxies are moving away from us, reasoned Hubble, then at some time in the past, they must have been clustered close together.
