<span> The highest ranked category or the highest taxonomic rank of organisms is a domain. Carl Woese designed three-domain system of taxonomy which includes Eukarya, Bacteria and Archea, and they differ in rRNA. The first includes all living organisms that have a nucleus and membrane-bound organelles and multicellular organisms. Other two are prokaryotic microorganisms or single-celled organisms whose cells have no nucleus. </span>
Portland, Oregon, is a city right next to northern west coast of the USA. Besides being very close to the sea, it is also laid on a river. The sun that heats up the ocean and the river leads to evaporation, causing water vapour to ascend, because of a few wind currents, this water vapour is taken to Portland's area where it colds down and condensates, raining over Portland.
Activation of muscle contraction could be a speedy event that's initiated by electrical activity within the surface membrane and transversal (T) tubules. This can be followed by unharness of metal<span> from the inner membrane system, the sarcoplasmic reticulum.

Answer:
a. the rough endoplasmic reticulum
Because it is the site of protein synthesis.
and all of the other organelles have no relation to protein and handling especially peroxisomes which detoxifies h202 and helps with intracellular digestion similar to the lysosomes and microtubules only function is for locomotion of prokaryotic cells and some eukaryotic cells like the sperm cell also they make up spindle fibers used to bind and separate chromosomes/chromatids in mitosis and meiosis.
