Exam 1
What is the Hardy-weinberg equation for allele frequency?
P + Q = 1
I have a fossil with 6.25% of the original mass of its radioisotope, and I know that it is definitively 5,000 years old. What is its radioisotope's half-life?
1,250 years
Radiolarians have what kind of pseudopodia?
Rod-like pseudopodia
Secondary growth occurs at what two places in plants?
The cork and vascular cambia
The sympoplastic route travels via the _____________.
Cytoplasm (plasmodesmata)
What is the Hardy-Weinberg Equation for genotypic frequencies?
P2 + 2PQ + Q2 = 1
Which two organelles specifically support the endosymbiotic theory? And give a reason why we believe this.
The mitochondria and chloroplast
They have their own ribosomes and DNA and make their own proteins
Gametophytes produce _____________, and sporophytes produce _____________.
Gametes and Spores
Ground tissue in plants is made up of what 3 kinds of cells?
Collenchyma, Sclerenchyma, Parenchyma
Does bulk flow occur more via the apoplastic or symplastic route?
What is the difference between the bottleneck effect and the founder effect?
The founder effect takes place when a group of organisms leaves their original population and founds a new population. The bottleneck effect takes place when a population is significantly reduced because of some event.
Come up to the board and draw a paraphyletic grouping
Has an ancestor and not all of its descendants
Which protist is most responsible for oxygenating the Earth's atmosphere?
Cyanobacteria
Name all of the parts of the female reproductive structure in angiosperms.
Carpel is made of the stigma, style, and ovaries (with ovules)
From what germ layer is the coelom formed?
Mesoderm
Analogous structures are similar structures that arrive due to convergent evolution, but homologous structures are similar structures that arrive from common ancestry but develop different functions.
Name all of the levels of classification from most to least specific
Species, genus, family, order, class, phylum, kingdom, domain
How do diplomonads typically get their nutrients?
They are heterotrophic (parasitic).
In a leaf, what is the function of palisade cells? How does the arrangement of the spongy mesophyll cells help the plant?
Palisade cells are arranged to maximize photosynthesis. Spongy mesophyll cells have plenty of space in between them so that gas can flow in an out of the plant and diffuse.
___________ grow with determinate spiral cleavage.
Protostomes
What are the 5 points of Hardy-Weinberg Equilibrium?
No mutations, no gene flow, large population, random mating, no natural selection
Was the BP oil spill a local or a global disturbance?
Local disturbance
