Rough ER
Explanation:
This type of Endoplasmic Reticulum has ribosomes around its outer membranes hence is a major organelle in the processing of cell proteins. When polypeptide chains are formed in the ribosomes, they enter the lumen of the RER where they are folded properly using chaperones and post-translational modification carried out on them.

For earthquakes, there's the Richter scale. For hurricanes, the Saffir-Simpson wind scale. For tornadoes, we use the enhanced Fujita scale. Now scientists are developing the wildland urban interface (WUI) hazard scale, a tool that will help predict the threat and measure the severity of wildfire.
<u>Change in thermal energy and particle arrangement of molten steel after becoming completely solid:</u>
Due to the rise in the temperature, the particles start moving speedily. Because of the achieving the kinetic energy, which helps in the higher collision rate and makes the diffusion rate high. In case of the solids the particles are strongly bound in sequential order. Even though we can’t see it, but the vibrations can be felt. During heating the internal energy increases and helps the particle to move faster.
Lost to the environment in the form of heat.
