Which statement about bacteria is false?
Bacteria belongs to the same domain of life as archaea
Why was aerobic respiration a requirement for the emergence of eukaryotes?
Because eukaryotic cells are much more complex than prokaryotes, greater amounts of energy are required for their metabolism.
There is a geographical barrier between two populations
Coevolution
This figure is representative of
Competitive exclusion
Which type of selection has the greatest potential to lead to dimorphism or speciation?
Disruptive selection
Which of the following is not a characteristic of Aegyptopithecus Zeuxis?
Had a very large brain
Studies of different species of warbles that live in Vermont coniferous forests have shown that to avoid conflict, the species nest and forage at different heights of the trees. This is known as
Microhabitat partitioning
Which of the following is incorrect regarding emergence?
Most properties of an emergent system can be predicted based on the properties of the individual components.
Which of the following is a biological macromolecule that can both store heritable information and catalyze chemical reactions?
RNA
Which statement about viruses is TRUE?
RNA viruses have higher rates of mutation than DNA viruses
The ENCODE Project revealed new insights about the human genome. Identify the one correct answer.
Recognition that evolutionary change occurs through sequences that alter gene regulation.
The graph shown below depicts the range in prey size for three species of lizard all living in the same habitat; the silhouettes show the relative average size for each species of lizard (note that the x-axis shows the size of prey, not the lizards themselves). This data demonstrates the concept of
Resource partitioning
You have isolated a gene from the human genome that codes for an enzyme. Because this enzyme could be a useful therapeutic, you want to make large quantities of it quickly and cheaply. To accomplish this goal you insert the gene into a plasmid and for expression in bacteria; however, when you transform bacteria with this DNA you find that it does not cause the bacteria to produce the enzyme. What is the most likely cause of this failure?
The gene contains introns which bacteria cannot splice out of mRNA transcripts.
Allopatric speciation implies that
There is a geographical barrier between two populations
As global temperatures continue to rise, which biome will most likely replace woodland / grassland / shrubland? Hint use the plot below to help answer this question.
Thorn forest/savanna thorn scrub
The below figure is a climatogram showing monthly mean precipitation and temperature with standard deviations. This climatogram is representative of what kind of biome?
Tropical rain forest
Under what circumstances can simple chance affect the frequency of genes in a population?
When the population is very small thus amplifying the effect of random chance.
Moderate levels of disturbance create conditions that
foster greater species diversity than low or high levels of disturbance (shortest option)
