Question

1. how are carbohydrates and lipids similar? how are they different?

Explanation:

Carbohydrates and lipids are both organic compounds that contain carbon, hydrogen, and oxygen. They are both sources of energy for the body.

Carbohydrates are made up of simple sugars (monosaccharides) that can be linked together to form disaccharides and polysaccharides. They are the body's primary source of energy, especially for the brain and muscles.

Lipids, on the other hand, include fats, oils, and steroids. They are more energy - dense than carbohydrates, providing more than twice as much energy per gram. Lipids also play important roles in insulation, protection of organs, and as components of cell membranes.

Answer:

Similarity: Both are organic compounds containing C, H, O and are energy sources. Difference: Carbohydrates (simple sugars linked) are primary energy (e.g., for brain/muscles); lipids (fats, oils, steroids) are more energy - dense (over twice per gram), also for insulation, organ protection, cell membranes.
