Answer:
Explanation:
Based on the scenario being described within the question it can be said that the most likely reason for this misconception would be that the spiral galaxies looked like clouds of gas and dust through telescopes because of their distance from Earth.

The Human Immunodeficiency Virus (HIV) has been discovered to be the cause of AIDS.
AIDS or Acquired Immunodeficiency Syndrome is caused by the Human Immunodeficiency Virus (HIV). HIV is a retrovirus which contains RNA as the genetic material.
HIV infection can be transmitted through:-
- sexual contact with an infected individual,
- transfusion of contaminated blood samples,
- sharing infected needles e.g. in the case of drug addicts who take the drug intravenously,
- infected pregnant woman to the fetus through placenta.
AIDS adversely affects the immune system of an infected individual. ELISA or enzyme linked immunosorbent assay test is used largely for diagnosing AIDS.

How do rivers become larger as they travel across land?
Tributaries combine, adding water to rivers.
A tributary is a stream that flows into a larger river. Small streams from around an area combine together to form a bigger tributary that eventually falls into rivers. This adds water to the main river, finally leading this river water out into an ocean.
It regulates cell division.
