Q

phylogenetic trees showcpatterns of descent, not phenotypic –, therefore it should never be assumed that a taxon evolved from-

25
DNA that codes for rRNA changes relatively slowly and is useful for investigating branching points hundreds of millions of years ago
True
26
mtDNA evolves rapidly and can be used to explore more recent evolutionary events
True
27
What type of genes are found in a single copy in the gnome and a are homologous between species?
Orthologous
28
What type of genes results from gene duplication, so are found in more than one copy of the gnome?
Paralogous
29
Humans and mice diverged about 65 million years ago, and 99% of
Our genes are orthologous
30
Gene number and the complexity of an organism are very strongly linked
False
31
how did we figure out that a specific strain of HIV likely spread to humans sometime in the 1930's?
Molecular clock
32
Describe the evolution of our understanding of classification and the tree of life
- Everything on this planet is plant and animals - we had five kingdoms -bacteria, archea, and eukarya adapted with RNA P.P. 58
33
There are more prokaryotic organism in a handful of fertile soil than
of people we have ever lived
34
What is the difference between the cells walls of Bacteria and Archaea?
Bacteria cells contain peptidoglycan
35
What are longer than timbre and allow prokaryotes to exchange DNA?
Pili
36
There are some difference between prokaryotic and eukaryotic DNA replication, transcription, and translation, why is this a good thing?
These allow people to use antibiotics to inhibit bacterial growth without harming
37
what do rapid reproduction, mutation, and genetic recombination contribute to in a prokaryotes?
Genetic diversity
38
Transformation, transduction, and conjugation, in prokaryotes, are all forms of what?
Genetics recombination
39
What allows for antibiotics-resitant strains of bacteria to become more common?
Natural selection
40
What is dental plague?
Biofilm
41
Name as many archaea/Bacterial groups. example and important/ interesting point that you can think
LOOK AT NOTES!
42
Write down as many example of bacteria being helpful to humans as you can think of
- Antibiotics - yogurt - healing concrete with limestone
43
What is a protist?
A eukaryotes that is not a plant, animal, and fungi
44
most protist are ----, although there are some colonial and multicellular one
Unicellular
45
Protist are the most ----- diverse organism
structurally
46
Some are the most --- diverse eukaryotes
Nutritionally
47
some protist are exclusively asexual, while most have sexual life cycles including --and ----
1. meiosis | 2. fertilization
48
Name as many protist phyla, or common name, or both, and something important or interesting about each of them, as you can think of.
PP.69-95
49
in regard to photosynthetic protist and prokaryotes in aquatic environment, we have noticed a trend that as sea surface temperature increase, ----
Biomass
50

52
What is your favorites gymnosperm?
cedar
53
Why is water no longer required for fertilization in the seed-producing vascular plants?
pollen grains are light enough to be carry by air or insects
54
what are the most recent, successful, diverse, economically/ecologically important group of plants on the planet today?
Angiosperm
55
Label this complete flower with all collective terminology

57
describe 5 post fertilization details
