Question

1. the nutrients that do not need to be digested before being absorbed are: carbohydrate, vitamins, minerals protein, water, fat water, vitamins, minerals carbohydrate, fat, protein 2) the nutrients and food substances that are absorbed by passive diffusion are: water, fats, alcohol carbohydrate, vitamins, minerals fat - soluble vitamins, water - soluble vitamins, alcohol protein, alcohol, fiber

Explanation:

1. Water, vitamins, and minerals are small - sized and simple substances that can be absorbed without prior digestion. Carbohydrates, proteins, and fats need to be broken down into simpler forms for absorption.
2. Water, fats, and alcohol can pass through the cell membranes by passive diffusion as they can dissolve in the lipid - based cell membrane or move down their concentration gradients easily. Carbohydrates, proteins, and most vitamins require specific transport mechanisms.

Answer:

1. Water, vitamins, minerals
2. Water, fats, alcohol
