Question 19 The best description of a prokaryote is that it is O a. typically a unicellular organism between 1 and 10 micrometers in size. O b. most commonly a eukaryotic organism between 1 and 10 micrometers in size. O c. generally found living and reproducing in isolation in inhospitable environments. O d. a set of unicellular organisms found living and growing in a common environment. O e. a unicellular organism between 1 and 2 millimeters in size.
Question 8 Currently, the only predators of Galápagos marine iguanas are Galápagos hawks. Iguana body size is not correlated with risk of hawk predation, although small iguanas can sprint faster than large iguanas. If predators (for example, cats) that preferentially catch and eat slower iguanas are introduced to the island, predict, using a graph, what would happen to iguana body size in the absence of other factors. A) Define what type of selection the Iguana would be under (directional, stabilizing, disruptive). B) After defining the selection currently described above; write a new scenario for the iguanas that would result in a DIFFERENT selection mode (aka not the one you selected before).
Question 21 A population of bacterial cells is growing optimally in a broth with a pH of 5. How would you classify this population of cells? O The bacteria are aeotolerant because they are growing with oxygen. The bacteria are neutrophiles because they are growing best at a neutral pH. O The bacteria are alkalinophiles because they are growing well in an acidic environment. O The bacteria are acidophiles because they are growing in an acidic environment.

QUESTION 1 Individuals who have two copies of the allele causing Bad-Breath syndrome can survive but fail to reproduce (that is selection, or s=1). Given the empirically measured mutation rate of 0.01, what is the equilibrium frequency of individuals that you expect to find in the population with Bad-Breath syndrome.
Question 9 Many sea mammals , fish, and birds have the same body form, i.e. whales, marlin, and penguins. Which of the following is the best explanation for this observation? This is the only shape that will allow them to maintain a constant body temperature in water. Their shapes are the result of convergent evolution, which reduces drag while swimming. All of the organisms needed to develop similar body shapes so they could swim. All of their bodies have been compressed since birth by intensive underwater pressures.

QUESTION 8 Emergent properties of living systems are defined as properties that_ O are apparent only when an organism is studied at the molecular level O are due to the arrangement and interactions of parts as complexity increases O are evident during only one portion of the life cycle of an organism O define the cell's surroundings O none of the above یے

C2 A Mountain River Is the following statement consistent with the data presented in the diagram, above? Choose True for yes, the statement is consistent with the diagram.

QUESTION 27 Microtubules are made of tubulin. When tubulin is bound to GTP, it has a higher affinity for other tubulin molecules, so microtubules grow. When tubulin is bound to GDP, the affinity is lower so microtubules shrink. We would say that tubulin is regulated by O Ubiquitylation O Phosphorylation O Small molecule binding O Protein-protein interactions
