Answer:
The correct answer is: 1. Muscular strength refers to the amount of force in one effort, while muscular endurance refers to repeated movements.
Explanation:
<u>As response 1 says, muscular strength shows how much effort we can put or what weight we can lift (our maximum force). It refers to a single action. On the other side, muscular endurance will tell how many times we can repeat that same action.</u>

Both of them deliver oxygen to cells.
<em>3. Muscular endurance refers to the amount of force in one effort,while muscular strength refers to performing repeated movements.</em>
It is the other way around.
<em>4. Muscular endurance refers to the efficiency of oxygen delivery to cells,while muscular strength refers to the ability to move joints.</em>
The same as in 2, in both situations, oxygen is being delivered to cells.
