It is made of cartilage-like tissue
It has no connection to nerves
It contracts rhythmically without tiring easily

Question 4: What happens when an antagonistic muscle pair works?
Both muscles always contract at the same time
The muscles turn into tendons during movement
One muscle contracts while the other relaxes
The bones move without muscle help
Question 5: What starts a skeletal muscle contraction at the fiber level?
A nerve signal triggers the fiber to respond
The muscle fiber makes new bone cells
The tendon shortens before the fiber activates
Fat cells dissolve to create movement
Question 6: In the sliding filament model, what actually changes during contraction?
The filaments disappear completely
Thin and thick filaments slide past each other
The bone lengths shrink temporarily
The muscle cells split into smaller cells
Question 7: Why does regular exercise help muscles become stronger?
It removes the need for ATP
It turns skeletal muscle into smooth muscle
It stops muscles from using oxygen
It increases fiber size and improves efficiency
Question 8: Why can a person get muscle cramps during intense activity?
The heart briefly stops producing blood
The bones stop supporting the body
Muscle tissue turns into connective tissue
Muscles may not relax properly when energy or balance is disrupted
