Does areboic respiration reqire oxygen to be present?
otherwise it would not be areobic...
What have scientist inferred from fossil stromatolites?
Stromatolites were much more abundant on the planet in Precambrian times which means that fossils found around stromatolites are typically from the Precambrian era.
Were the first organisms that released oxygen as a by-product of photosynthesis?
No, they were not Toxic was actually poinsonous to the Anaerobic photoautotrophs. However cyanobacteria (a.k.a pondscum) is believed to be the first bacteria to give off oxygen as a by-product of photosynthetic processes.
What are found on the outer surfaces of stromatolites?
Biofilms of microorganisms, especially cyanobacteria, are found on the outter surfaces of stromatolites.
During which period did the presence of stromatolites decline?
Proterozoic is called the "Age of Stromatolites" (Abundant in Proterozoic shallow seas)
Why is javelin anaerobic sport?
It is an areboic sport because you have to use all of your body to get a good throw. you have to twist and turn your upper body so you use the same motions as aerobic sport.
