Answer:
RER is involved in protein synthesis, folding, transport and modification.
Explanation:
The Endoplasmic Reticulum is an organnelle found in eukaryotic cells. They are of two types; Rough Endoplasmic Reticulum and Smooth Endoplasmic Reticulum, so named based on the appearance of their surface. The Rough Endoplasmic Reticulum (RER) obtains it rough appearance from the membrane bound ribosomes attached to it.
Due to the ribosomes that attach to them during protein synthesis, their function is very much associated with protein synthesis. They are primarily involved in protein production, which would either remain in their lumen for further modification/processing called Glycosylation (adding sugar to proteins to form glycoproteins) or be transported through secretory vesicles to the Golgi apparatus. They also fold this proteins in their inner membrane structure called cisternae.
<span>Air masses rise and sink due to the fact that warm air is lighter than cold air , thus warm air rises and cold air then sinks. When air masses rise, gaseous molecules are transported into the atmosphere which negatively impacts the ozone layer.</span>

Divergent evolution<span> occurs when two different species share a common ancestor but have different characteristics from one another
</span>
Evolution<span> is the idea that the animals and plants that are alive today have developed from past organisms.
</span>
Convergent evolution<span> occurs when two different species do not share a common ancestor but have developed similar characteristics through adaption to similar environmental conditions.
</span>
<span>Co-evolution is the influence of closely associated species on each other in their evolution.</span>
