Taxonomy
What is the purpose of taxonomy?
Classifying and naming organisms.
What is the half life of carbon 14
5730
What are the 3 types of adaptations?
Structural, physiological, and behavioral
How much energy is passed from each trophic level?
10 percent
When does crossing over happen?
Prophase 1
What is the mnemonic for taxonomy categories
Dumb kids playing catch on the freeway get smashed
Whats the definition of half-life
Time for half of a radioactive sample to decay.
What is an example of a structural adaptation
thick fur or webbed feet
Metric System
Standardized system used worldwide in science; makes conversions simple by shifting decimals. Base units are meter (m) for length, gram (g) for mass, liter (L) for volume.
How is meiosis different from mitosis?
meiosis produces 4 non-identical haploid cells; mitosis produces 2 identical diploid cells.
Who invented taxonomy
Carl Linnaeus
What is a cladogram
Diagrams showing evolutionary relationships based on shared traits.
What is an example of behavioral adaptation
hibernation and migration
Why is there normally not a 4th or 5th trophic level?
not enough energy left over because of the 10 percent rule
homologous chromosomes split during which phase of meiosis?
Anaphase 1
What are the taxonomic categories
Domain, kingdom, phylum, class, order, family, genus, species
What is radioactive dating
determining the age of objects using radioactive isotopes
What is an example of physiological
venom and temperature regulation
Chemical equation for photosynthesis
6 CO 2 + 6 H 2 O → C 6 H 12 O 6 + 6 O 2
What is the purpose of meiosis? What are the products?
Produces gametes (sperm or egg cells) for sexual reproduction and ends with 4 haploid cells
what are the 6 kingdoms
What is phyletic gradualism and punctuated equilibrium
Phyletic Gradualism: Evolution occurs slowly and steadily over long periods.
Punctuated Equilibrium: Long periods of stability interrupted by rapid evolutionary change.
3 types of symbiosis
Mutualistic, commensal, and parasitic
What happens in the light dependent reactions?
chlorophyll captures sunlight to split water molecules, releasing oxygen and producing ATP and NADPH
Why do gametes produced in meiosis contain only one allele for each gene?
Because homologous chromosomes separate, placing one allele in each gamete.
