Over the years, bacteria have become less sensitive to antibiotics used for medicinal and sanitation purposes. This lack of sensitivity is termed antibiotic resistance. How is antibiotic resistance an adaptation? A.
Antibiotic resistance has caused antibiotics to become more specialized, thus adapting the antibiotics to particular bacteria species.
B.
The trait giving bacteria antibiotic resistance has reproductively isolated groups of bacteria.
C.
The trait giving bacteria antibiotic resistance has become common, giving bacteria with the trait a selective advantage.
D.
Antibiotic resistance makes it more difficult for bacteria to infect hosts, thus is a selective advantage for the host.

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?
