Ascientist is designing an investigation to study the impact of the neck length of tortoises on survival rates in the galapagos islands. what is most likely the outcome variable (dependent variable) in this investigation? neck length survival rate number of predators galapagos island environment

Neck length is what is going to change so that is the Independent Variable. The Dependent Variable is the Survival Rate.

Hope this helps

Hiii!! The correct answer would beNeck Length, since the survival rate depends on the Length of the Neck! :)

b - the respond is innate and varies over time.

good luck!
