Edwin Hubble's observation of galaxies revealed that the light received from them were red-shifted, indicating that they are moving away from us. And the seemingly farther away a galaxy was, the greater its red-shift. This can only be explained if a all the galaxies were expanding outward. Determining the exact distances to the other galaxies was a problem, however, until the Hubble space telescope. It had high enough resolution to identify Cepheid variable stars in other galaxies, and accurately determine their distance, and therefore the expansion rate of the universe. Hope this helps!!

It follows that no other cell in the body performs a neuron's exact functions.
<h3>
What about neurons?</h3>
- Information is transmitted via neurons.
- They communicate between various brain regions and between the brain and the rest of the nervous system through electrical impulses and chemical signals.
- The basic building blocks of the brain and nervous system are neurons (also known as neurones or nerve cells).
- The cells known as neurons are responsible for receiving sensory data from the outside world, sending commands to our muscles, and converting and relaying electrical signals at various points along the road.
- The bulk of neurons in vertebrates are found in the central nervous system, however some are found in peripheral ganglia and many sensory neurons are found in sensory organs like the retina and ear.
- A neuron is made up of a cell body, which includes a nucleus and cytoplasm, from which long, thin portions that resemble hair grow.
- The neuron's lone long component, known as the axon, is responsible for carrying nerve impulses to various body areas.
- Dendrites are the short, branching components of the neuron.

♦Activation requires calcium binding to troponin complex, reversing inhibition of interaction between myosin and actin. In the cycle of chemical reactions underlying contraction, hydrolysis of ATP produces the cross-bridge motion. Relaxation occurs when calcium becomes dissociated from troponin.
