scientists have created dogs that are twice as strong as they would be naturally, through genetic engineering of the myostatin protein. the myostatin protein inhibits muscle growth, deleting this gene allowed the dogs to grow more muscular. the process used on the dog embryos could help prevent some human genetic disorders that affect the muscles of humans, like muscular dystrophy (a degenerative muscle disorder) based on their success with the two dogs, scientists stated it was possible for humans to be similarly genetically modified

Turtle hatchling survivorship rate is low in many turtle species due to predation. amanda researched the predatory rate on a species of turtle eggs in the red river. the eggs were harvested from trapped turtles and the egg's cloaca film (reproductive discharge) was either washed off or left on once gathered. research suggests that predators use the female's cloaca scent to locate the eggs. the eggs were only handled when wearing gloves and then reburied along islands where the turtles were trapped. the nests were monitored by cameras and manually on foot and data on nest predation were recorded. a. based on the experimental design, what is the dependent variable? b. based on the experimental design, what is the independent variable? c. based on the experimental design, what is the control?
