Overexpression of proteins using bacterial vectors: Group of answer choices requires a bacterial promoter to be present in the bacterial vector. always results in a properly folded, active protein. makes subsequent purification of the recombinant DNA harder. requires eukaryotic ribosome binding sites to be present in the bacterial vector. is so effective the expressed protein can represent as much as 80% of the total bacterial protein.

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e. g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.
