How are bacteria able to adapt to a rapidly changing environment? a) during transcription, rna polymerase is unable to bind and commence transcription. b) bacterial genes, in a rapidly changing environment, mutate rapidly in response to these changes. c) bacterial genes are organized into operons, clusters of coregulated genes, that are regulated such that they are all turned on or off together. d) bacterial cells are prokaryotic and genes have ready access to the ribosomes within the cell's cytoplasm. transcription, then, take place at a very rapid rate.

What are the types of mutations, and how does each alter the encoded protein? college level answer

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.
