Please help, i need this to study, i dont get it, make the answer clear

A student wanted to test the effectiveness of a new type of drug that
would increase the activity of Ca2+ ATPases on the sarcoplasmic
reticulum. She had a population of 15 frogs and divided them into
three groups: 5 frogs received 50mg of the drug, 5 frogs received
25mg of the drug and 5 frogs received a placebo. She isolated the
gastrocnemius from each frog and attached it to a force transducer
and collected data from single twitches. She also recorded the air
temperature in Steinhaus Hall because temperature would affect
enzyme activity. What should she measure as her dependent
variable?
t5 duration
stimulus voltage
Frest
air temperature

Step 1: Introduction

Sarcoplasmic reticulum is a cell organelle in muscle cells that is equivalent to that of the endoplasmic reticulum of other cells. Sarcoplasmic reticulum is used to store calcium ions which are required for muscle contraction. Release of calcium ions from the sarcoplasmic reticulum through calcium pump (Ca ²⁺ATPase) into the cytoplasm of muscle cells activates actin and myosin filaments of muscle. This aids in the contraction of muscle fibers. This mechanism is also accompanied by an electric signal which causes a twitch in the muscle fiber.
