Most pathogenic bacteria are chemoheterotrophs. This means:
• Chemo - they obtain energy by the oxidation of electron donors (get their energy from chemical reactions, unlike phototrophs which use solar energy.
• Heterotrophs – they are unable to fix carbon to form their own organic compounds so they use organic (chemoorganoheterotrophs) or inorganic (chemolithoheterotrophs) components as energy sources.
Pick a point on the graph-
Mass= 24 and volume =4
Density = mass/ volume
Density = 24/4 = 6

I believe the best answer from the choices listed above is the third option. The Theory of spontaneous generation was A theory that wasdisproved by Redi and Pasteur. Hope this answers the question. Have a nice day. Feel free to ask more questions.
