Consider the diagram of reproduction of yeast cells. Yeast can reproduce both asexually and sexually. During sexual reproduction, alpha or a cells produce ‘a-factor’, which signals the presence of an a cell to neighbouring α cells and the a cells also respond to α factor. Each cell grows a projection towards the opposite cell and this response of haploid cells to the mating factors of the opposite mating type allows for conjugation between a and α cells, but not between cells of the same mating type. What is the advantage to this type of reproduction?

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.
