Answer:
The correct answer is microfilaments.
Explanation:
The cytoskeleton of our play a significant role in providing mechanical support and maintaining the proper shape of the body cells.
Cytoskeleton is composed of mitrotubules, microtubule and intermediate filaments.
Microfilaments are also known as actin filaments that composed of actin polymer that interacts with myosin during muscle contraction.
Microtubules also helps in cytokinesis,cell movement,maintenance of cell shape,cellular contraction and relaxation.

Kidneys
Explanation:
All vertebrates have kidneys. Like the human kidney, they are made up of many nephrons. However, there are differences in the structure and functioning of various vertebrate kidneys that adapt them to the environment in which the animals live.
There are 3 kinds of contraction in skeletal muscle:
Concentric contraction: The muscle in this contraction will gives force more than the load gives. This will make the muscle shorten as it pulling the load.
Eccentric contraction: In this contraction, the force given by muscle is not enough to pull the load. This causes the load pulling the muscle instead. So the muscle will be lengthened as the load moving away.
Isometric contraction: In this contraction, the length of the muscle will be kept same by adjusting the force given to be equal to the force needed.
