Question

a researcher conducts an experiment to see if mitochondria produce carbon dioxide at different rates in different types of tissues. examine the data obtained during the experiment. rate of carbon dioxide production (bubbles/sec) type of tissue at rest after 5 sec of exercise after 15 sec of exercise after 30 sec of exercise after ending exercise skeletal muscle 5 8 10 12 8 heart muscle 8 12 15 21 10 liver 3 3 3 3 3 stomach 3 3 3 3 3 brain 5 8 8 10 5 which variable is the independent variable? type of tissue in which mitochondria are located rate of carbon dioxide production time that carbon dioxide production was measured number of carbon dioxide bubbles per second

Explanation:

An independent variable is what the researcher manipulates or changes. Here, the researcher is looking at different types of tissues to see how mitochondria in them produce carbon - dioxide. The type of tissue is being varied, while the rate of carbon - dioxide production is the dependent variable that changes based on the tissue type and time. Time is also a factor but secondary to the tissue type in terms of what is initially varied.

Answer:

type of tissue in which mitochondria are located
