The structure of the two endoplasmic reticulum makes the difference.
Endoplasmic reticulum (ER) is located in the cytoplasm membrane in the eukaryotes and its divided into two the rough and smooth endoplasmic reticulum.
Rough ER has ribosomes which gives it the name rough because of its appearance. The ribosomes on rough ER helps it to specialize in the synthesis of proteins. proteins in a cell, are synthesize by it. The smooth endoplasmic reticulum lacks ribosome in its structure and cannot synthesize protein but lipids.
The most likely explanation of as to why there is a high
proportion of winged individuals in a population of bean aphid was because
there is a presence of high population density or another reason is that there
is already a high population if before the aphids develop or has developed.
fats are composed of high amounts of saturated fatty acids which are solid at room temperature and oils are composed of mainly unsaturated fatty acids which are a liquid at room temperature
