Bio 121 Final Exam Questions With All
Verified Solutions.
Taxonomy - Answer study of naming/classifying
Phylogeny - Answer evolutionary history
In a phylogenic tree, what does a longer line infer? - 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? - Answer Archae Bacteria, Eubacteria, Protista, Plantae, Fungi, Animalia
What kingdom was split to create the sixth kingdom? - Answer Monera was split into Archae Bacteria
and Eubacteria
What are the differences between eucaryotes and prokaryotes regarding reproduction and organelles? -
Answer Eukaryotes reproduce sexually and asexually and they have many organelles. Prokaryotes
reproduce asexually only and have few organelles.
What distinguishes the three domains? - Answer sequence ribosomal RNA
What are the three domains? - Answer Bacteria, Archaea, and Eucarya
What are the six requirements for life? - 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? -
Answer Major metabolic pathways (glycosis), replicate DNA, genetic codes
, When climates are unfavorable, what do bacteria do? Plants? Animals? Protista? - Answer
Bacteria/fungi - produce spore
Plants - seed/go dormant
Animals - hibernate/migrate
Protista- cyst (protective stage)
Explain autotrophy vs heterotrophy. - 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? - Answer Chemoautotrophs (energy from chemical compounds)
and photoautotrophs (energy from light)
What is a facultative heterotroph? Example? - Answer They can feed through organic and inorganic
substances (carnivorous plants)
Which of the six kingdoms are heterotrophic and which are autotrophic? - Answer Archae Bacteria -
Autotrophic
Eubacteria - Both heterotrophic and autotrophic
Protista - Mainly heterotrophic, some are autotrophic
Plantae - Autotrophic
Fungi - Heterotrophic
Animalia - Heterotrophic
What are carbohydrates? - Answer .sugars and starches
What are the functions of carbohydrates? - Answer source of energy, energy storage, structural
components
What is the structural component of plants? Fungi? - Answer Plants - cellulose
Fungi - chitin
