,dont cause human disease
2 types of eukarya - CORRECT ANSWER-protists and fungi
what is the largest of the 4 cellular microbes - CORRECT ANSWER-protists

Are molds and mushrooms multicellular or unicellular? - CORRECT ANSWER-
multicellular
what are the life determining characteristics - CORRECT ANSWER-ability to
reproduce
must be separate from environment (membrane)
respond to its environment
, heredity
metabolism
What was early earth like? - CORRECT ANSWER-no oxygen, therefore could not
sustain current lie
Miller-Urey Experiment - CORRECT ANSWER-they simulated early earth in a lab
(no o2)
after a week the water became black with amino acids
this showed that vital organic molecules for life can form in a strongly reducing
atmosphere.
what was the earliest molecule that could help create life - CORRECT ANSWER-
RNA, the molecule was thought to need a hereditary and a metabolic function
RNA has both
what is the catalytic molecule of RNA - CORRECT ANSWER-ribozyme
endosymbiotic theory - CORRECT ANSWER-theory that eukaryotic cells formed
from a symbiosis relationship among several different prokaryotic organisms by
allowing one to live inside the other
What 2 organelles are involved in the endosymbiotic theory? - CORRECT
ANSWER-mitochondria and chloroplasts
3 pieces of evidence for endosymbiotic theory - CORRECT ANSWER-1.
