I tried my best to answer.
1) Chemical to mechanical (calories -> muscle contractions)
2) mechanical to mechanical (muscle -> motion)
3) mechanical to thermal (motion -> heat from the body causes sweating)
The potential energy is stored in the body chemically (via food). That potential energy is then released when the body is put in motion.
An electromagnet is a kind of magnet whose magnetic field is created by flow of electric current. The magnetic field disappears when the current stops.
The greatest advantage of an electromagnet over a permanent magnet is that it has the advantage of controlled holding power and on - command release.
Through the application of controlled DC electric current, electromagnets have the ability to attract and hold ferrous materials with varying degrees of force and to release the item as required.
Answer:
Si no es posible refutarla, dicha teoría queda «corroborada», pudiendo ser aceptada provisionalmente, pero no verificada; es decir, ninguna teoría es absolutamente verdadera, sino a lo sumo «no refutada».

Answer:
The cell membrane
Explanation:
This is the phospholipid bilayer that everything that wants to come into the cell has to move throught. It is also selectively permeable.
Industrial revolution produced pollution, which became the reason of black pepper moth. When time passed, they became more suitable by the process of natural selection.
hope this helps!
