Bio 121 Exam #1 Dr. Minchella UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Taxonomy - CORRECT ANSWER - study of naming/classifying
Phylogeny - CORRECT ANSWER - evolutionary history
In a phylogenic tree, what does a longer line infer? - CORRECT ANSWER - That it took
longer for evolution to occur between the two species than the two species with the shorter line.
What are the six kingdoms? - CORRECT ANSWER - Archae Bacteria, Eubacteria,
Protista, Plantae, Fungi, Animalia
What kingdom was split to create the sixth kingdom? - CORRECT ANSWER - Monera
was split into Archae Bacteria and Eubacteria
What are the differences between eucaryotes and prokaryotes regarding reproduction and
organelles? - CORRECT ANSWER - Eukaryotes reproduce sexually and asexually and
they have many organelles. Prokaryotes reproduce asexually only and have few organelles.
What distinguishes the three domains? - CORRECT ANSWER - sequence ribosomal RNA
What are the three domains? - CORRECT ANSWER - Bacteria, Archaea, and Eucarya
What are the six requirements for life? - CORRECT ANSWER - Metabolism,
reproduction, genetics, evolution, growth (populations), and adaptation
, What are some examples of common solutions that species use when lacking the requirements
for life? - CORRECT ANSWER - Major metabolic pathways (glycosis), replicate DNA,
genetic codes
When climates are unfavorable, what do bacteria do? Plants? Animals? Protista? - CORRECT
ANSWER - Bacteria/fungi - produce spore
Plants - seed/go dormant
Animals - hibernate/migrate
Protista- cyst (protective stage)
Explain autotrophy vs heterotrophy. - CORRECT ANSWER - Autotrophy - self-feeding
(synthesize organic compounds from inorganic sources)
Heterotrophy - other feeding (synthesize energy from organic substances)
What are the two types of autotrophs? - CORRECT ANSWER - Chemoautotrophs (energy
from chemical compounds) and photoautotrophs (energy from light)
What is a facultative heterotroph? Example? - CORRECT ANSWER - They can feed
through organic and inorganic substances (carnivorous plants)
Which of the six kingdoms are heterotrophic and which are autotrophic? - CORRECT
ANSWER - Archae Bacteria - Autotrophic
Eubacteria - Both heterotrophic and autotrophic
Protista - Mainly heterotrophic, some are autotrophic
Plantae - Autotrophic
Fungi - Heterotrophic
Animalia - Heterotrophic
What are carbohydrates? - CORRECT ANSWER - .sugars and starches
