Answer: An independent variable, sometimes called an experimental or predictor variable, is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable, sometimes called an outcome variable.
Explanation: Example: What is a good outcome variable for deciding whether cancer treatment in a country has been improving?
A first thought might be "number of deaths in the country from cancer in one year." But number of deaths might increase simply because the population is increasing. Or it might go down if cancer incidence is decreasing. "Percent of the population that dies of cancer in one year" would take care of the first problem, but not the second.
This example makes the point that a rate is often a better measure than a count.
Answer:
Letter a. Yes, yeasts can exist in an oxygen-poor environment.
Explanation:
Mitochondria are an organelle that we can find in the majority of eukaryotic cells. Mitochondria help in produces the energetical molecule of ATP. We start with one molecule of glucose that passes through a process called glycolysis to convert glucose into pyruvate. This pyruvate molecule can follow two pathways: when oxygen is available the pyruvate enter into the Krebs cycle and proceeds to the respiratory chain in the mitochondria, when oxygen is not present, pyruvate pass into another pathway, one is the alcoholic fermentation producing ethanol and dioxide of carbon.
As yeast are a eukaryotic organism, they have mitochondria and can grow in the presence of oxygen. When oxygen is absent yeast can grow using the fermentation pathway producing alcohol.
