Apharmaceutical company is testing a new drug that they claim allows dogs to repel
flea infestation. they give 100 dogs the medication and another 100 dogs a sugar
pill.
which of the following is true of this experiment?
the sample size is too low.
the sugar pill would be a placebo.
the independent variable is the number of fleas on dogs.
the dogs with the placebo would be the experimental group.

The sugar pill is called a placebo.

Explanation:

The placebo), is a harmless sugar pill that would have no effect on any of dogs.

The "control" group is the group that had the actual medication. This is the group they will b checking to see if any fleas or how many fleas r on the control group to gauge the success or failure of the medication.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
