A student is shown a picture of a large number of stars clumped together without a discernible shape. The student argues that these stars cannot be a galaxy because all galaxies have familiar shapes such as barred, elliptical, and spiral. Is the student correct? A.
Yes. These stars cannot be a galaxy if they do not form a familiar shape.
B.
The stars cannot be a galaxy, but the student incorrectly lists "barred" as a possible shape. All galaxies are either elliptical, spiral, or spheroidal.
C.
Although all galaxies have familiar shapes, no single image can capture an entire galaxy. If the student could see the entire galaxy, it would have a familiar shape.
D.
No. The stars could be part of an irregular galaxy.

D.

Explanation:

Irregular galaxies have no identifiable shape or structure to them. They are often chaotic in appearance, without a bulge or any trace of spiral arms.

1.A Characteristic refers to the distinctive qualities that make up an individual. A trait, on the other hand, is a feature of an individual which is inherited. The main difference between a characteristic and a trait is while a characteristic needs to be built by a person and absorbed, a trait comes genealogically.
