HESI A2 (BIOLOGY) ELSEVIER|Latest Update Graded A+ Why is polarity the most important characteristic of water? The results of the polarity are hydrogen bonding, a high specific heat value, and its versatile solvent properties. Athletes are often concerned with the question of what they need in their diets to increase muscle mass and strength. What biologic molecule would you recommend that would accomplish this? Proteins Which organelle would you expect to be present in a cell responsible for detoxifying multiple molecules? Smooth endoplasmic reticulum A cell from heart muscle would more than likely contain an unusually high proportion of: Mitochondria Which part of cellular respiration produces the greatest amount of ATP?
