LATEST UPDATE GRADED A+
What is the general name for the organisms that we study in
microbiology? Microbes or microorganisms.
Where do we find microbes? Everywhere
Which is the least heavily occupied biospheric zone associated with
our world. Atmosphere.
What do we call the mix of microbes that inhabit our intestines? Microbes or
microorganisms
What do we now know is the most influential determinant of a
healthy human gut (intestine)? Balanced (heterogeneous) symbiotic intestinal microbiome.
What determines a sub-microbiome of a human? location.
The conditions offered for microbial growth in that region of the human.
Approximately how old is the Earth and when did the first life-forms
evolve? 4.9 Billion years old, 3.5 Billion years old, bacterial-like organisms
What is the single most important contribution made by early
life-forms to life on earth?
, Does this contribution continue and if so to what extent (percentage).
By what process is this contribution achieved. oxygenation of our atmosphere;
Yes 70%;
the process is oxygenic photosynthesis.
Are viruses living organisms? No, they have no cellular structure.
What is the ultimate goal of Koch's postulates? identity of infectious organisms.
What is the process that led from the earliest organisms on earth to
all the plants, animals and ourselves that occupy the planet now? evolution.
What are the scientists called that specialize in determining
relationships between organisms in order to classify them? Phylogenists
Phylogeny is the evolutionary history of the relationships between
life-forms and the broad lines of descent that unite them.
Phylogeny represents the underlying hierarchical structure by which
life-forms evolved and are related to one another.
