In this activity, you’ll open your non-dominant hand (the hand that you don’t use for writing) and then squeeze it into a tight fist as quickly as you can for 100 seconds and write down the number of squeezes every 10 seconds. If you have access to a ball, you can squeeze the ball with your non-dominant hand instead. How do you think the number of squeezes you can perform will change over the course of the experiment? How many squeezes do you think you can perform during the last 10 seconds of the experiment?

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?
