Two of these answers are mixed up and I need help to figure out which two those are The sternum is anterior/ventral to the vertebrae.
The feet are inferior to the hands.
The elbows are lateral to the abdomen.
The skin is superficial to the skeleton.
The heart is posterior/dorsal to the sternum.
The lungs are deep to the ribs.
The chest is superior to the abdomen.
The knee is distal to the hip.
The fingers are medial to the thumb.
The elbow is proximal to the wrist.
The answers i have in italics are what i chose. it tells me i have two wrong and i can't figure out which two need switched.

The correct answers are "The heart is posterior/dorsal to the sternum" and "The lungs are deep to the ribs".

Explanation:

It is not true that the heart is posterior/dorsal to the sternum. Actually, it is considered that the heart is deep to the sternum, as well as the aorta, vena cava, and thymus gland. On the other hand, the lungs are posterior/dorsal to the ribs. The lungs are located in the thoracic cavity, which is extending anteriorly and laterally to the ribs.

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.
