Researchers studying a genetic disease use DNA sequences from a large group of both healthy people and people suffering from the genetic disease. The genetic disease is caused by a mutation in a single gene.
Why does it benefit researchers to use two groups of people?
By using both groups, the researchers can determined it's the same mutation causing the disease.
O By using both groups, the researchers can investigate each person individualy and determine the fitness of the individual
O By using both groups, the researchers can hypothesize which mutations will arise and cause the disease to evoke
By using both groups, the researchers can conclude how a person's llestyle is impacted by repeated testing

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.
