Answer:</h2>
The galaxies were classified based on the shape and structure exhibited by them.
<h2>
Explanation:</h2>
In the 1920's, the galaxies were classified based upon the shape and structure by famous scientist Edwin Hubble. He did it by a telescope with which he captured various galaxies existing. He ordered (or "arranged") their shapes as winding, banned winding, curved, sporadic, and impossible to miss. This framework was known as the Hubble morphological succession of cosmic system types.
Hubble noticed that a few universes, similar to the M31-Andromeda Galaxy, showed up as circles and had arms of stars and residue which showed up in a winding example. Like M31, these worlds showed up almost uniform in splendor. Likewise, Hubble saw that in a portion of these sorts of worlds the arms were all the more firmly twisted around the cosmic system. He called these winding systems. Our Galaxy, the Milky Way, is a case of a winding universe.

Answer:
(b)-osmosis
Explanation:
Osmosis -
In terms of biology , it is a form of diffusion , which is linked to the cells of the body .
The process of diffusion when the molecules and the atoms move from the region of high concentration to a region of lower concentration .
This is done in the presence of a semi - permeable membrane , which allows only a certain substance or molecules to pass via it .
hence , the correct term for the given statement is (b) - osmosis .
B. I think, because they are both mechanical. Don't quote me on that <span />
D. Are made of cells and DNA
DNA is genetic material in living organisms that is transferred from the parents. Cells and this DNA gives organisms personalized traits. Hope this helped !!
