There are still some anaerobic microorganisms in existence today. Botulism is a form of anaerobic bacteria that can cause human harm.
No, not all.
Extinct (Extinction)
Not all anaerobic bacteria are spore formers. While some anaerobic bacteria, such as those in the genera Clostridium and Bacillus, are known for their ability to form spores as a survival mechanism in harsh conditions, many other anaerobic bacteria do not produce spores. For example, genera such as Bacteroides and Fusobacterium are anaerobic but do not form spores. Therefore, spore formation is not a universal trait among anaerobic bacteria.
352 None, they are all extinct.
No, they are not. There is now way all eagles are extinct.
Yes, all dinosaurs are extinct. They all went extinct millions of years ago. The exact cause of why they all went extinct is debated by scientist and anthropologist.
The Thylacine (or Tasmanian Tiger is extinct). Also all Australian megafauna is extinct.
They are not extinct in South Africa
Extinct. Yes, ALL dinosaurs are extinct.
Snakes are not extinct. Some species may be, but certainly all are not. Check Extinct Snake Species.
Running, for all humans, starts off as aerobic. But, if, during a run/jog/workout, your body cannot continue to complete aerobic respiration, running then becomes anaerobic (aerobic and anaerobic meaning with and without oxygen). So, if you push your body enough, you will reach anaerobic running. The point at which running goes from aerobic to anaerobic is the anaerobic threshold.
None. They are all extinct.
