Biology 151 Exam Rated A+ (Verified)
100% Correct Answers
What does a phylogenic tree do - Answer ✔✔- show a hypothesis about how organisms
are related
Snakes are more closely related to _______ than _______. - Answer ✔✔- Lizards than
tuatara
tuatara than crocodiles
which evolved more recently. Crocodiles or tuatara? - Answer ✔✔- crocodiles
Would "Lizard" be considered a monophyletic group? Why or why not? - Answer ✔✔-
No because it does not pass the "one snip test". If you were to cut out the lizard group
in one spot you would also get snakes. It has a common ancestor but does not include
the rest of the descendants.
cocci arrangements - Answer ✔✔-
bacilli arrangements - Answer ✔✔-
Gram positive bacteria - Answer ✔✔- have a thick cell wall surrounding their cell
membrane
will be purple as a result of the gram stain
conjugation - Answer ✔✔- physical contact of two bacterial or protist cells is required to
transfer DNA.
transduction - Answer ✔✔- a virus is required to transfer bacterial DNA.
Transformation - Answer ✔✔- A bacterium takes up "naked" DNA from the environment.
viral structure - Answer ✔✔- Capsid is made up of capsomere proteins
RNA or Genetic material contains the information to make new proteins
Envelope is the structure that's made from the cell of the membrane host
Explain why viruses are living - Answer ✔✔- They can reproduce, they have a genome,
they adapt to their environment, and they respond to stimuli
Explain why viruses are non-living - Answer ✔✔- they are a-cellular (no cell membrane)
which violates cell theory, they cannot regulate themselves (no homeostasis), they rely
on host for protein synthesis, no metabolism (can't generate ATP)
, endosymbiotic theory - Answer ✔✔- primary endosymbiosis- prokaryote + eukaryote =
eukaryote
eukaryote takes in prokaryote
Secondary endosymbiosis- eukaryote + eukaryote = eukaryote
eukaryote takes in eukaryote
evidence that supports the endosymbiotic theory - Answer ✔✔- circular dna, ribosomes
are similar in size to bacterial ribosomes, replicate via binary fission, double membrane
amoebozoans - Answer ✔✔- protists move using lobe-shaped pseudopodia (ex. slime
molds)
alveolates - Answer ✔✔- Unicellular, often photosynthetic protists that move using cilia.
eukaryotes and alveolates - Answer ✔✔- diatomes, dinoflagellates, and radiolarians
could all be classified into these groups
What ingredients in a salad made of lettuce, mushrooms, and turkey. What components
are opisthotonos? - Answer ✔✔- Protists, fungi, and animals
mushrooms and turkey would be opisthokonts
asexual reproduction results in offspring genetically identical to the parent, while sexual
reproduction produces genetically different offspring - Answer ✔✔- true
A single celled fungus known as _________, can reproduce asexually through
_________ - Answer ✔✔- yeast
Budding
The body of multicellular fungus called a ________ and is made up of multiple
threadlike structures called __________ - Answer ✔✔- Mycelium
Hyphae
In times of stress, fungi can form a ______, which produce and release spores. -
Answer ✔✔- Fruiting body
decomposer - Answer ✔✔- an organism produces an enzyme to digest cellulose in
plant cell walls.
pathogen - Answer ✔✔- an organism that causes disease in its host.
facultative parasite - Answer ✔✔- a fungal species can either absorb nutrients as
molecules from the environment or acquire them from a host.
