Compare and contrast the physical and chemical conditionson Earth at the time life first arose with conditions today.From a physiological standpoint, discuss at least two reasonswhy animals could not have existed on early Earth. In whatways has microbial metabolism altered Earth’s biosphere?How might life on Earth be different if oxygenicphotosynthesis had not evolved?
Microbial Physiology
Microbial physiology is the branch of microbiology that is associated with studying the physiology of fungi, bacteria, and viruses. It is an important field of science concerning functional genomics and metabolic engineering.
Chemotaxis
The organism’s movement in a particular direction as a response to certain chemicals that are available in the environment is defined as chemotaxis. In brief, it can be defined as the occurrence of an organism’s movement in response to a certain chemical stimulus.
