Question

what do fish, cheese, eggs, bacon, olive oil, and nuts have in common? fat. fats are part of a diverse group of molecules called lipids. lipids include phospholipids, waxes, and steroids. lipids are one of the three main types of macromolecules, or large carbon - based molecules, found in the foods we eat, along with carbohydrates and proteins. lipids perform many different functions. for example, fats store energy for later use, while phospholipids are the building blocks of cell membranes. waxes form protective barriers on animals and plants. steroids function as chemical messengers in many processes in the body. select the true statements. lipids are used to build cell membranes. steroids are a type of lipid. lipids are used for quick - acting, short - term energy in cells. walnuts, salmon, and butter are dietary sources of lipids.

Explanation:

1. For "Lipids are used to build cell membranes": The text says "phospholipids (a type of lipid) are the building blocks of cell membranes", so this is true.
2. For "Steroids are a type of lipid": The text states "Lipids include phospholipids, waxes, and steroids", so this is true.
3. For "Lipids are used for quick - acting, short - term energy in cells": Lipids are for long - term energy storage, while carbohydrates are for quick - acting, short - term energy. So this is false.
4. For "Walnuts, salmon, and butter are dietary sources of lipids": The image and text show foods like nuts (walnuts), fish (salmon), and butter as sources of fat (a type of lipid), so this is true.

Answer:

• Lipids are used to build cell membranes. (True)
• Steroids are a type of lipid. (True)
• Lipids are used for quick - acting, short - term energy in cells. (False)
• Walnuts, salmon, and butter are dietary sources of lipids. (True)

The true statements are: "Lipids are used to build cell membranes", "Steroids are a type of lipid", and "Walnuts, salmon, and butter are dietary sources of lipids".
