Sickle cell anemia is an inherited, autosomal disease.
Under a microscope, gram-positive bacteria (when dyed with the gram stain) appear in purple-colored structures due to the peptidoglycan cell wall.
<h3>What are gram-positive bacteria?</h3>
Gram-positive bacteria are microorganisms (bacteria) that may be colored with crystal violet stain due to the presence of a peptidoglycan-based cell wall.
In conclusion, under a microscope, gram-positive bacteria (when dyed with the gram stain) appear purple-colored structures due to the peptidoglycan cell wall.

One of the events that could give credence to the panspermia hypothesis would be the presence of carbon-based molecules on meteors that strike the earth's surface.
<h3>Evidence of extraterrestrial lives</h3>
All biomolecules of life are carbon-based. Examples of these molecules include carbohydrates, proteins, ribonucleic acids, etc.
In order for life to exist in a place, carbon must be abundant.
Thus, the presence of carbon-based molecules on meteors from another planet that hit the surface of the earth may be evidence that life exists on another planet.
This can be used as evidence that life on earth came from extraterrestrial sources.
