Suppose that another scientist writes a rebuttal to the findings presented in Investigating Life 26.1. The scientist suggests that a mutation in the myosin gene is unlikely to be the cause of smaller jaw muscles. The scientist proposes that it is much more likely that the first human ate softer food and therefore did not exert the jaw muscles, so they became smaller. These smaller jaw muscles were then passed on to offspring. What is the most appropriate response to this alternative proposal

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.
