____________ happens in the cytoplasm, whereas _____________ happens in the mitochondrion.
Aerobic respiration; anaerobic fermentation
Glycolysis; the citric acid (Krebs) cycle
The citric acid (Krebs) cycle; mitochondrial electron-transport
Anaerobic fermentation; glycolysis
The Correct Answer is B
A. Aerobic respiration; anaerobic fermentation: Aerobic respiration primarily occurs in the mitochondrion, and anaerobic fermentation occurs in the cytoplasm. Therefore, this is incorrect.
B. Glycolysis; the citric acid (Krebs) cycle: Glycolysis occurs in the cytoplasm, breaking down glucose into pyruvate. The citric acid (Krebs) cycle takes place in the mitochondrion, where it further processes pyruvate for energy production.
C. The citric acid (Krebs) cycle; mitochondrial electron-transport: Both the citric acid cycle and the mitochondrial electron transport chain occur in the mitochondrion.
D. Anaerobic fermentation; glycolysis: Glycolysis occurs in the cytoplasm and is the first step in both aerobic and anaerobic pathways, but anaerobic fermentation also occurs in the cytoplasm, so this option is not accurate in distinguishing between processes happening in different locations.

Correct Answer is B
Explanation
A. Liver; small intestine: Carbohydrate and protein digestion do not begin in the liver or the small intestine. The liver is involved in metabolism but not in the initial digestion of carbohydrates or proteins.
B. Mouth; stomach: Carbohydrate digestion begins in the mouth with salivary amylase, while protein digestion begins in the stomach with pepsin.
C. Small intestine; stomach: Carbohydrate digestion begins in the mouth and not the small intestine. Protein digestion starts in the stomach, not the small intestine.
D. Mouth; small intestine: Carbohydrate digestion begins in the mouth, but protein digestion begins in the stomach, not the small intestine.
Correct Answer is B
Explanation
A. Wastes; nutrients and oxygen: Wastes pass from the fetal blood to the maternal blood, and nutrients and oxygen pass from the maternal blood to the fetal blood.
B. Oxygen and nutrients; wastes: Oxygen and nutrients pass from maternal blood to fetal blood, and wastes pass from fetal blood to maternal blood.
C. Wastes and nutrients; oxygen and carbon dioxide: Nutrients and oxygen pass from maternal to fetal blood, while wastes and carbon dioxide pass from fetal to maternal blood. This option is incorrect because it lists wastes and nutrients incorrectly.
D. Carbon dioxide; nutrients: Carbon dioxide and other wastes pass from fetal to maternal blood, while nutrients pass from maternal to fetal blood.
