5.1: Evidence for Evolution
Blank, is the cumulative change in the heritable characteristics of a population...
What is evolution?
In a species where there is variation, a blank will eliminate some but not all members of the population.
What is change in the environment?
The system of naming organisms using two names...
What is binomial nomenclature?
Blank is the study of clades, which are groups of organisms that have evolved from a common ancestor
What is cladistics?
The petrified remains/traces of plants and animals...
What are fossils?
True or false: Natural selection tends to eliminate from a population individuals that show low fitness, whereas the fittest individuals in a population have a higher likelihood of surviving.
What is true?
Fix this statement: The first name in the binomial nomenclature system is always capitalized and refers to the species; the second name always begins with a smaller letter and refers to the genus
What is refers to the genus for the first name, and refers to the species for the second name
Correct the statement/True or false: Two species of organisms are more closely related to each other when there are more differences between them due to mutations?
What is false? What is two species of organisms are less closely related to each other when there are more differences between them due to mutations
Blank on earth is constantly changing...
What is life?
The consequence of competition for resources to stay alive is called...
What is the struggle for survival?
The three domains of life are...
What is Archaea, Eubacteria and Eukaryote?
The time where two species diverged from a common ancestor can be found by...?
What is comparing similarities and differences between the DNA base sequence of the two species?
Another answer: By comparing the similarities and differences between amino acid sequences of a protein of the two species
In this phrase made by Darwin, it states " Blank were not just a coincidence, but evidence that organisms in question have a common ancestor"
What are homologous structures?
True or false: Exactly which individuals survive and which ones do not is not based on chance alone but determined by their surroundings and the compatibility of their blank with those surroundings
What is characteristics?
What is true?
The names of the 7 level hierarchy of taxa in order...
What is kingdom, phylum, class, order, family, genus ,and species?
Blank is a diagram used to visually represent the findings of cladistics
What is a cladogram?
Polymorphisms are...
What is the different versions of a species?
The two sources of possible change in the genetic makeup of bacteria
What is mutations?
What is plasmid transfer?
A blank is what a biologists use to establish which taxa a species belongs to when they encounter an unrecognized species
What is a dichotomous key
The two types of characteristics that are considered when ordering the traits of organisms into certain clades are..
What are analogous and homologous characteristics?
