Bio Lab Practical Flashcards
What is primary literature?
Publications that present original research and results
Citing properly
- MLA/APA citations
- author
- year
- title
- journal
Parts of a graph
- x and y axis labels
- legends
- descriptive title
- figure summaries
How do you determine if evolution is taking place by looking at allele frequency?
If the allele frequencies are changing, evolution is occurring.
What are the three evolutionary processes?
- Natural selection
- Gene flow/ migration
- Genetic drift
For a population to be in Hardy- Weinberg Equilibrium, what are the 5 conditions that have to be met?
- NO Mutation
- NO Natural selection
- NO gene flow
- Random mating
- Very large population size
Allele fixation
When one allele reaches 100% frequency
Sequence data
When you compare DNA sequences to estimate divergence
Divergence time
Fewer differences mean= more recent common ancestor
Character tables
The presence or absence of traits can be use to analyze or infer relationships
Three main trophic levels
Producers: make their own energy from the sun
Primary consumers: only consume the producers
Secondary consumers: Consume primary consumers and producers
Mosses are ___ dominant and ferns are ___ dominant.
gametophyte, sporophyte
Alteration of generation cycle
GAMETOPHYTE GENERATION (n)
Meiosis produces ___ –>
Mitosis produces ___ –>
then gametes get fertilized
spores, multicellular gametophyte
After fertilization: SPOROPHYTE GENERATION (2n)
Fertilization creates a ___ that undergoes mitosis.
Antheridia and Archegonia
Antheridia: the male reproductive organ (produces sperm) in mosses and sperm
Archegonia: the female reproductive organ (contains one egg)) in mosses and sperm
Antheridia and archgonia grow at the tips of the ___ shoots. After fertilization the zygote forms into the ___, which grows into the sporophyte
gametophyte, archegonium
