Growth in the larva of young arthropods is restricted by:
Correct answer: A. Exoskeleton
- A. Exoskeleton
- B. Appendages
- C. Endoskeleton
- D. Reduced mitosis
Explanation
As the body underneath the exoskeleton grows, the animal begins to outgrow its tough exterior. In order to cope with this situation, arthropods undergo a process of shedding their exoskeleton and forming a new one periodically throughout their lifetime. This process is called molting, or ecdysis.

About Support and Movement
Support and movement covers the axial and appendicular skeleton, bone structure, joints and the arrangement of skeletal muscles. Muscle contraction is explained through actin, myosin, sliding filaments, calcium ions and ATP, while arthritis is distinguished as a disorder of joints rather than a normal part of movement.
