(Code 5) Darwin's theory of evolution offers a scientific explanation for changes in
changes in species over time
(bottleneck effect or founder effect)

persons that were wrongly convicted of a crime
(Code 5) According to Darwin's theory of evolution, surviving species have a better ability to...
survive and reproduce (greater fitness)
(Code 9) Mutations can increase genetic variation as it changes the base sequences of DNA, but mutations are also beneficial in that can increase this....
an individuals ability to survive and reproduce (fitness)
(Code 6) Compared to the Carolus Linneaus system of classification (scientific names), the advantage of classifying species into clades is that clades show...
evolutionary relationships
(Code 11) Mitochondria and Chloroplasts have their own DNA and make some of their own proteins...giving a possible explanation for this theory where it is believed the modern day eukaryote evolved from an ancient, anaerobic prokaryote.....
Endosymbiotic Theory
(Code 9) In DNA fingerprinting, DNA undergoes a process called gel electrophoresis leaving a sample of dark bands that are....
DNA fragments of different lengths
(Code 5) Structures such as chickens, horses, frogs, and alligators have the same structure of bones due to having a common ancestor, but different functions making these......
homologous structures
(Code 6) An example of a major decline in medium-tan crabs is due to a change in beach color making the medium-tan crabs more....
visible to predators
Organisms that survive mass extinctions evolve rapidly because they face limited competition...an example of this would be...
(The Cambrian Explosion or The Great Dying)
The Great Dying
(Code 3) The cell walls of fungi are made of this...
chitin
(Code 7) Gene therapy is a process that _______the defective gene and cures the patient of the disorder...
replaces
(Code 5) What evidence did Darwin used this to support his explanation of why species had different beak shapes and sizes...
the finch species lived and had to adapt to different islands due to isolation
(Code 10) DNA sequences used in determining the prior history leading up to speciation can be a useful strategy by comparing these sequences from each species for....
the same gene
Much like hummingbirds and flowers, ants and acacia plants have built a symbiotic relationship in which both species benefit from being with each other (ants get nectar/acacia plants have unwanted bacteria removed by ants) making these types of relationship a specific type of evolution called....(co-evolution or bi-evolution)
coevolution
Radiometric dating (figuring out rates of decay/half-life) to estimate the age of rocks and other objects (absolute age) is also used on fossils:
(true or false)
(Code 9) An issue that can arise from the use of DNA fingerprinting
privacy or consent issues
(Code 6) Snakes having hip bones that have no function anymore are called vestigial structures which show evolutionary descent from...
a common ancestor
(Code 10) The average birth weight for babies is 7lbs...despite there being weights smaller and larger. This is an example of ________selection.
stabilizing
(Code 7) Punctuated equilibrium can be described as...
rapid changes and speciation in "spurts"
(Code 3) For now, Protists have their own kingdom due to the fact that they can be challenging in terms of classifying due to being very similar to these kingdoms.....
