Question

question 6 which of the following has a polar head and nonpolar tails? carbohydrate integral protein phospholipid question 7 which reaction builds a polymer? dehydration hydrolysis

Explanation:

For Question 6, phospholipids have a polar phosphate - containing head and non - polar fatty acid tails. Carbohydrates are generally polar and integral proteins have various polar and non - polar regions but not in the distinct head - tail structure like phospholipids. For Question 7, dehydration reactions link monomers together to form polymers by removing a water molecule, while hydrolysis breaks polymers into monomers by adding water.

Answer:

Question 6: C. phospholipid
Question 7: dehydration
