Given what is known about humans, why is it unlikely that a thermophile or a psychrophile would be a human pathogen?

If you are working at a sewage treatment plant, which microbial process(es) would you use to reduce nitrates in sewage before releasing into rivers? Why? denitrification; to reduce occurrence of HAB's nitrification; to make water richer in fertilizers when used by farmers nitroge fixiation; to increase dissolved oxygen in river water nitirification to convert nitrates to unusable nitrites; to increase algal growth in water

a)  bacteria are “obligate anaerobes.” What does this mean? On Earth, where might these organisms live? (Give examples.) b) Humans (and most Eukaryotic organisms) are obligate aerobes. What does this mean? On Earth, where might these organisms live? (Give examples.)

Beer is produced by yeast fermentation of grain to ethanol. Why must the process of beer production be anaerobic?

An organism that gets its energy for ATP from the sun and synthesizes C-C bonds from simple molecules D.)An organism that gets its energy for ATP from inorganic molecules and synthesizes C-C bonds from simple molecules

We’re going to make our own yogurt using mixed bacteria cultures which contains Lactobacillus casei, Bifidobacterium longum, Lactobacillus bulgaricus, Streptococcus thermophiles, Lactobacillus acidophilus How can you tell if you successfully made yogurt? What are the functions of all different species in the mixed yogurt cultures?

When my environment dries out, i am capable of losing all the water from my body and surviving in this dormant state for many years in the chance that water may someday return. This unique truck I preform is called... 1.) Autohydro resuscitation  2.) Torpor 3.) Dessication 4.) Bioaqueous estivation  5.) Anhydrobiosis
