|
What was the contribution of Caolus Linnaeus?
|
classified all organism so when different people looked @ the same organism, they would both know the name
|
|
|
What is binomial? (Many call it binomial nomenclature.)
|
two parts (genus and species)
|
|
|
Name all the divisions of classifying organisms from largest division to smallest.
|
Domain Kingdom Phylum Class Order Family Genus Species (Did King Phillip Come Over For Good Spaghetti)
|
|
|
When the division was first identified, how many were there and what where they called? (of kingdoms, names of kingdoms)
|
two kingdoms (plant and animal)
|
|
|
What is the scientific name for humans?
|
Homo sapiens
|
|
|
What does dichotomous mean? You will be expected to complete a dichotomous key for the essay and/ or in the multiple choice section.
|
dichotomous= divided in 2; two choices (that sort of thing)
|
|
|
Name the 5 things that scientists used as a basis for the classification system.
|
1.DNA
2.Biochemical analysis 3.Embryology 4.evolutionary phylogeny/ phylogenic tree |
|
|
What is a phylogenic tree?
|
a diagram that indicates common ancestors and lines of descent
|
|
|
What does a phylogenic tree show the observer? You should be able to look at a phylogenic tree and determine the order of evolution.
|
the evolutionary history of a group of organisms
|
|
|
Name and define the three things link classification to evolution?
|
phylogenic tree, conversion of evolution, co-evolution
|
|
|
Compare and contrast prokaryotic and EUKARYOTIC cells.
|
eukaryotic: large, have nucleus; consists of nuclear membrane and nuclei, has membrane bound organelles, cell wall is chemically simple, plasma membrane is chemically complex, complex chromosomes
|
|
|
compare and contrast eukaryotic and PROKARYOTIC
|
small, no nuclear membrane/nuclei, no membrane bound organelles, cell wall usualy chemically complex, plasma membrane chemically simple, simple chromosomes
|
|
|
Compare and contrast unicellular and multicellular
|
unicellular: one cell, very simple
multicellular: multiple cells, more complex |
|
|
List 4 facts about viruses.
|
1.smaller than prokaryotes
2.not a cell 3. not living 4.must infect and use living cells to reproduce |
|
|
Explain how a virus attacks and reproduces inside a cell. (what does the host do?) ESSAY
|
virus attatches tail fibers to protein site, inserts its DNA (the rest of virus is now useless), when cell copies its DNA it makes more of the virus, cell explodes with lots of new viruses
|
|
|
Name and explain the 3 common viruses discussed in class.
|
influenza: flu virus, symptoms vary from persson to person and type of virus
smallpox: highly contagious, bumps on skin errupt, can be fatal HIV: (human immunodeficiency virus) white blood count decreses, immune system sucks. |
|
|
Why is there no vaccine for HIV yet?
|
the HIV virus mutates too quickly
|
|
|
Why do we have to get a flu vaccination every year? What theory does this support?
|
because it mutates, this supports evolution and survival of the fittest (natural selection)
|
|
|
How are most viruses treated?
|
vaccinations (use tamiflu when you already have it)
|
|
|
What kingdom are bacteria in?
|
eubacteria
|
|
|
How are bacteria important for our current atmosphere?
|
use CO2 and put out 02, but now not as usefull because we have trees that do that more effectively
|
|
|
Write 3 facts about bacteria.
|
help our bodies digestive system, destroy harmful organisms in our body, used to make cheese, milk, and sourdough bread
|
|
|
How many bacteria are helpful?
|
99%
|
|
|
Explain how bacteria reproduces.
|
BINARY FISSION
1. DNA duplicates 2. DNA seperates and moves to both sides of cell 3. cell begins to divide (cross wall) 4. 2 daughter cells seperate |
|
|
Name a common type of bacteria.
|
amoeba, paramecium, volvox
|
|
|
How is bacteria treated?
|
antibiotics
|
