The sarcomere<span> </span><span>is the basic unit of a </span><span>striated muscle and the force of a muscle is directly related to the extension that the sarcomere is under. When a sarcomere is extended from 1.5 micrometres to about 3 micrometres, the muscles' force is great and max at about 2/2.5 micrometres. When the muscle is fully extended and, therefore, the sarcomere is extended over than 3 micrometres, the muscle force decreases exponentially.</span>

<span>Red blood cells normally have a biconcave shape (picture a donut, but instead of a hole through the centre there's just a downward slope to the centre of the cell). If the cell takes on water, it will increase in size and the sloped areas will start to flatten out. If the cell loses water, it will begin to shrivel. Use these observations and your understanding of osmosis to answer the question!</span>
        
                    
             
        
        
        
Answer: An object's motion can change physically by humans, Physically by humans The action from a force can cause an object to move or can speed up accelerate, to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it could be said that a force on an object results in the acceleration of a object.
