contaminated water
HINT: be on your GUARD (giardia) when drinking water in a different country
3 kinds of Protista - CORRECT ANSWER: fungus-like, animal-like, plant-like
**because Protista are POLYphyletic, fungus-like is closer to fungi than animal-lke
About the Eras - CORRECT ANSWER: Precambrian- single celled bacteria (before
Paleozoic) Paleozoic- paleo means old; age of invertebrates then vertebrates evolved Mesozoic- meso means middle; dinosaurs (reptiles) Cenozoic- ceno means recent; big rock hit; age of mammals & vertebrates
ANIMAL LIKE PROTISTS - CORRECT ANSWER: Phylum Sarcodina (flesh spin)
Pseudopods— false feet Amoebae Foraminiferans— produce calcium Radiolarians— composed of Silvia dioxide
Autotrophs - CORRECT ANSWER: Make their own food from organic molecules; some
of the oldest fossils were autotrophs
- / 3
Binomial nomenclature - CORRECT ANSWER: capitalize 1st letter & underline to signify italics. Writing it like this shows that its a scientific name aka GENUS
Cellular Slime Molds - CORRECT ANSWER: Phylum Ascrasiomycota
Pseudo plasmodium A raisin— phermone released to attract cells to form pseudoplasmodium
Chemotrophs - CORRECT ANSWER: obtain energy from chemicals obtained without
light

Earliest life forms were anaerobic/aerobic and autotrophic/heterotrophic - CORRECT
ANSWER: Earliest life forms were anaerobic and heterotrophic
Cretaceous Extinction - CORRECT ANSWER: occurred between Mesozoic and
Cenozoic; whiped out everything. rip dinosaurs.

Genosperms - CORRECT ANSWER: genosperm like pines were evolved from hit
because they protected themselves from dinosaurs (think of pines; very deadly to consume)
H2S vs H2O - CORRECT ANSWER: H2S was originally being used to be the source of
high energy electrons in photosynthesis because the first organisms were anaerobic (the byproduct then became sulfur). Eventually, H2O became the source of high energy electrons in photosynthesis (the byproduct then became oxygen). Lead to Oxygen Crisis.
Haldon-Oparin Hypothesis - CORRECT ANSWER: life arose spontaneously from
methane, ammonia, water & energy sources
HETEROTROPHIC PROTISTS - CORRECT ANSWER: fungus like
Kingdom Archaezoe - CORRECT ANSWER: LACKS MITOCHONDRIA BUT NUCLEI
PRESENT
Kingdom Protista - CORRECT ANSWER: Diverse group; polyphyletic
Can be consumers, producers or moth (mixotroph)
Milley-Urey experiment - CORRECT ANSWER: Tested Haldane-Oparin hypothesis
