The most common source of contamination with E.coli is by eating contaminated food like meat and eggs.
Answer:
The correct answer is -
Independent variable - the amount (time period) of light given to pots.
Dependent variable - size of tomatoes
Control variable - dark or absence of light
Control group - pot placed in the darkroom.
Explanation:
The independent variable is the variable that is changed or manipulated in particular research or study to see the effect of that variable on dependent variable. In this case, the amount of light each pot gets is the independent variable.
The dependent variable is the variable that depends on the change in the independent variable. The size of tomatoes is the dependent variable here.
The control variable is the variable that remains in standard condition or condition which can be used to compare with the effect of the independent variable. The absence of light on one of the tomato pot is the control variable.
The control group is the group of subjects did not get any treatment that experiment group receives. The pot which is placed in the dark room is control group here.
Fermentation is the process by which a carbohydrate molecule is broken down into alcohol and carbon dioxide in the absence of oxygen. During this process, two molecules of ATP is produced. In the absence of oxygen, pyruvate formed from glycolysis will undergo fermentation process. During the process of fermentation, NADH from glycolysis will be converted back to NAD+. This is necessary in order for glycolysis to continue. Thus, fermentation regenerate more NAD+ and only a few molecule of ATP.
This is more common sense rather than biology, but talking to someone would slow it down, so you know it’s not c or e. The best idea is b
I believe its D. All of the above
