Exoskeleton and Endoskeleton
Multicellular organisms e.g. man meet their needs through use of specialized systems that they have in their bodies. Examples of such include:
1. cardiovascular system composed of heart, veins and arteries which facilitate transport of nutrients to all parts of the body .
2. Skeletal system composed of bones, joints, ligaments and cartilage whose function is support and protection of the body. <span>
3. Digestive system composed of mouth, esophagus, stomach , small and large intestines whose function is breakdown of food and absorption of nutrients.</span>

Answer:
Resistance because you will get tested on everything I think this will be the most important one yet.
Explanation:
Answer:
Fast glycolytic fibers use anaerobic metabolism to produce energy which is used by the muscle for high tension contraction but these muscles fatigue quickly.
- It has amount amount of glycogen and have very quick acting myosin ATPase.
Slow oxidative are known as resistant fibers which generates energy(ATP) by the help of aerobic system.
- It depends on the delivery of oxygen and have red fibers which is smallest of all the fibers.
- It is found in marathon runners and its main function is to maintain posture.
