Answer:

The muscle must change its contraction, wave summation and twitch mode.

Explanation:

Muscle tissue is important for the contraction and movement of an organism. Muscles contain important protein like actin, myosin and troppomyosin that helps in the movement of a particular part of a body.

While lifting a box, if someone put extra weight the muscle will shift from isometric to isotonic contraction. The muscle decreases the wave summation and turns to fast twitch mode for the continuous contraction and lifting the box.

Explanation:

The nervous system is one of the most important systems of the animal body which helps in the transmission of the signals to and fro from the body to the nervous system.

The evolution of this system is the basis of the evolution of the human species as it helped and tried the species to sense the external environment most efficiently as well as improved the response to the environment.

The nervous system improved the response by forming new interactions with each other and responding to it by reducing the response time through reflex actions which formed fast acting response to the environment. The transmission of signals improved as the cells were long-lasting that is present form the birth of an organism  

Thus,  option-E is the correct answer.
