how do the hypothesis of microspheres and the rna world hypothesis build off of each other?
a. microspheres were important for storing and releasing energy for surrounding organisms that contained rna.
b. nonorganic molecules self-replicated within the early microspheres, similar to the way cells divide.
c. replicating rna molecules transformed into dna within the microspheres.
d. when microspheres split, the genetic coding in self-replicating rna would pass to the newly formed microsphere.

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.
