A biologist trying to determine the mechanism of adenosine triphosphate (ATP) production in a newly discovered bacterium provides several different substrates on which the bacteria can feed. Which of the following results would indicate that the species uses fermentation to produce ATP?

1.After the bacteria break down their substrate, the biologist notices a rotten egg smell.
2.The biologist discovers that the bacteria are able to produce organic molecules by metabolizing methane.
3.After exposure to amino acids, the bacteria produce a smell like rotting flesh.
4.The bacteria utilize glucose and produce carbon dioxide as a by-product of respiration

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.

i think that it is c, d, and e, hope this
