What is the job of DNA polymerase?
joins individual nucleotides to produce a DNA molecule.
|
What is the difference between natural selection and artificial selection.
Humans, not the environment, select which organisms survive and reproduce.
|
What are the characteristics of arthropods?
exoskeleton and jointed appendages.
|
What is the original source of energy in most ecosystems.
Sunlight
|
What is cloning?
using a single cell to create a population of genetically identical cells
|
|
What is translation.
the cell uses information from messenger RNA to produce proteins.
|
What are three types of reproductive isolating mechanisms that lead to speciation.
Behavioral Isolation, Temporal Isolation, Geographical Isolation.
|
What is a derived characteristic?
a characteristic that arises as a lineage of organisms evolves over time.
|
What is a food web?
an ecological model of the relationships that form a network of complete interactions among organisms in a community from producers to decomposers.
|
What is Gel electrophoresis?
separates the fragments of DNA by length
|
|
What is a nucleotide of DNA
deoxyribose + phosphate group + cytosine
|
What is adaptive radiation
when a single species evolves into several different forms that live in different ways, such as dinosaurs and the Galapagos finches.
|
What are the 4 characteristics of all chordates?
dorsal hollow nerve cord, post anal tail, pharyngeal pouches, notochord.
|
What is mutualism?
the relationship between two organisms who each benefit, such as a termite who is able to digest wood because of microbes that live in their gut.
|
What are restriction enzymes?
proteins used to cut DNA into shorter sequences
|
|
What is a translocation chromosomal mutation
transfers genes from one chromosome to another chromosome, resulting in a protein that will not be created correctly.
|
What are the conditions required to maintain genetic equilibrium, meaning evolution is not happening. .
No Mutations, No Migration, No Natural Selection, Random Mating, Large Populations
|
Why did scientists add the domain to the Linnaean classification system?
the two groups of prokaryotes differ greatly from each other and from eukaryotes.
|
What is phase one of logistic growth?
during this phase many limiting factors, such as competition for food and nesting groups, have little to no effect on population growth.
|
What does the fox say?
ducks say quack & fish go blub, & the seal goes ow ow ow, but there's one sound that no one knows
|
|
Why can an amino acid be specified by more than one kind of codon.
There are 64 different kinds of codons, but only 20 amino acids.
|
Why was Darwin's theory of evolution more powerful than the proposals of the other scientists?
While other scientists also cited examples from nature, and had logical ideas about evolution, Darwin explained the mechanism by which evolution occurred.
|
What is mutualism?
the symbiotic relationship between two species, such as termites who are able to digest wood because of microbes that live in their gut.
|
What is carbon dioxide
expelled as a waste product, this gas is removed from the atmosphere by photosynthesis.
|
