2) garrod hypothesized that "inborn errors of metabolism" such as alkaptonuria occur because a) metabolic enzymes require vitamin cofactors, and affected individuals have significant nutritional deficiencies. b) enzymes are made of dna, and affected individuals lack dna polymerase. c) many metabolic enzymes use dna as a cofactor, and affected individuals have mutations that prevent their enzymes from interacting efficiently with dna. d) certain metabolic reactions are carried out by ribozymes, and affected individuals lack key splicing factors. e) genes dictate the production of specific enzymes, and affected individuals have genetic defects that cause them to lack certain enzymes.

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?
