Proteins on the surface of vesicles determine where the vesicles go. which cell organelle provides the instructions for these proteins? a. endoplasmic reticulum b. lysosome c. mitochondria d. nucleus

The correct answer is option A, that is, Endoplasmic reticulum.  

The function of the nucleus is to function as the brain of the cell, while the endoplasmic reticulum function as a packaging and manufacturing system. It functions in close tandem with the ribosomes, Golgi complex, tRNA, and mRNA.  

The endoplasmic reticulum performs various functions, involving the folding of the molecules of proteins in the sacs known as cisternae and the conduction of the synthesized proteins in the vesicles to the Golgi apparatus.  

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds
