Ribosomes in eukaryotes can either be free, which means they are moving freely in the cytoplasm, or bound, which means they are affixed to the endoplasmic reticulum or the outer nuclear envelope.
The huge network of linked, membranous, infolded, and twisted sacks that are found in the cytoplasm of the cell is known as the reticulum (rough ER)
Ribosomes on the surface of rough ER give it a rough appearance.
The ER membrane is directly connected to the ribosome that is generating the protein.
Rough endoplasmic reticulum, often known as rough ER, is a phrase used to describe places where these membrane-bound ribosomes coat the ER surface.
Hence, the structure directly outside the nucleus that has ribosomes bound to it is called endoplasmic reticulum.

Answer:
They are necessary because, in fresh water, the concentration of solutes inside a cell is greater than that outside the cell, so the cell constantly absorbs water through osmosis

Primary succession is a method of fertilizing soil that was barren and had never supported plant life, for example soil left over by a moved glacier of lava.
I would say that Melissa has made the mistake of using the same uncleaned cutting board first for cutting up chicken which is notorious for forming bacteria quickly when out of the fridge and then chopping vegetables on it thus running the possibility of contaminating the vegetables with chicken bacteria. She should ensure she washes the cutting board carefully with soap and water to avoid contamination of the vegetables.
The answer that best fills in the blank would be pernicious.
A woman complains of chronic gastritis, fatigue, weight loss, and tingling in her fingers. laboratory findings show low hemoglobin and hematocrit levels, and a high mean corpuscular volume. these findings are consistent with pernicious anemia.
