A snake species that has migrated from the mainland to a small island eats banana slugs instead of lizards and mice, its usual diet. Which statement best explains this change in behavior? 1. The genotype that affects food choice is not isolated to a single phenotype.

2. Instinctual food choice by snakes is not related to genotypic flexibility.

3. Diet is exclusively controlled by snake genetics, not by nature.

4. Gene expression for mainland snakes is rigid and confined to one phenotype.

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.
