Answer:
<u>Amniotic fluid</u>
Explanation:
Amniotic fluid found in the uterus is capable of forming different types of cells thus said to be self-renewal. However the cells have limited differentiation but when grown in conducive conditions in the lab, the cells can form different tissues like bones, liver, muscle cells and brain.
The amniotic fluid suspends the foetus allowing it to grow and move freely. It also protects the foetus from damage by any pressures acting on the mother's womb.

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.
