Answer:
Rough endoplasmic reticulum extends from the nucleus to the cell membrane and holds ribosome at its surface.
Explanation:
Endoplasmic reticulum is of 2 types rough endoplasmic reticulum and smooth endoplasmic reticulum.
Rough endoplasmic reticulum is named so because it contain ribosome on its surface as a result rough endoplasmic reticulum play a significant role during translation or protein biosynthesis.
Rough endoplasmic reticulum extends from the nucleus that"s why most of the proteins of rough endoplasmic reticulum is accessed by the nucleus and if any proteins of RER or rough endoplasmic reticulum is not properly folded or misfolded then specific signals are send from nucleus for the correct folding of proteins of RER.
Physical and chemical changes may be similar because neither can change the number of atoms of each element that are present.
<h3>What do you mean by Physical changes?</h3>
Physical changes may be defined as those changes which appeared physically like color, odor, texture, mass, and density.
Chemical changes may lead to the formation of new chemicals with definite properties. It involves when the chemical identity of any substance may alter.
Therefore, physical and chemical changes may be similar because neither can change the number of atoms of each element that are present.
