14C-labeled lysine was added to an in vitro translation system consisting of purified components necessary for E. coli translation and the rest of the amino acids in unlabeled form. In one experiment, the in vitro translation was performed in the absence (-) of RNA template. In a second reaction, in vitro translation was performed in the presence (+) of poly(U) RNA template. The amount of radioactive polypeptide produced was measured as acid precipitable cpm. What results, A, B, C, or D, would be expected for these two experiments?

Use the drop-down menus to label each of the following changes p for physical change and c for chemical change.

Imagine that a mouse has white fur because of a mutation in its dna. which of the following conclusions can be drawn

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?
