Ques: Answer the following question given this paragraph: 4.2 Newton's First Law of Motion: Inertia Newton's first law of motion states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This is also known as the law of inertia. Inertia is the tendency of an object to remain at rest or remain in motion. Inertia is related to an object's mass. Mass is the quantity of matter in a substance. Q: What is the tendency of an object to remain at rest or remain in motion called? Choices: - impetus - magnetism - flow - inertia A:
Ans: inertia

Ques:Answer the following question given this paragraph: Proteins are nutrients made up of smaller molecules called amino acids . Recall that there are 20 different amino acids arranged like "beads on a string" to form proteins. These amino acid chains then fold up into a three-dimensional molecule, giving the protein a specific function. Proteins have several important roles in the body. For example, proteins make up antibodies, muscle fibers and enzymes that help control cell and body processes. You need to make sure you have enough protein in your diet to obtain the necessary amino acids to make your proteins. Q: How many amino acids are arranged like "beads on a string" to form proteins? Choices: - 15 - 35 - 25 - 20 A:

Ans:20
