The answer is Spiral Arms

leonid [27]3 years ago

Answer:

Spiral arm

Explanation:

Spiral galaxies are huge collections of billions of stars, most of which are flattened into a disk shape, with a spherical, glowing star bulge at its center. Inside the disc, there are typically shiny arms where younger, shinier stars, gas and dust are found. These arms move away from the center in a spiral pattern, giving the galaxies this name. Spiral galaxies look a bit like holes, or like water running down a drain. They are some of the most beautiful objects in the sky.

How is form used in classification?
Yuri [45]
Form classification is the classification of organisms based on their morphology, which does not necessarily reflect their biological relationships. Form classification, generally restricted to palaeontology, reflects uncertainty; the goal of science is to move "form taxa" to biological taxa whose affinity is known.
