Ribosomes are found in many places around a eukaryotic cell. You might find them floating in the cytosol. Those floating ribosomes make proteins that will be used inside of the cell. Other ribosomes are found on the endoplasmic reticulum. Endoplasmic reticulum with attached ribosomes is called rough ER. It looks bumpy under a microscope. The attached ribosomes make proteins that will be used inside the cell and proteins made for export out of the cell. There are also ribosomes attached to the nuclear envelope. Those ribosomes synthesize proteins that are released into the perinuclear space.
You can find most of the mountains in Mexico in one of two regions. The highest mountain peaks are located in the state of Puebla. The main mountain range in Mexico--the Sierra Madre Mountains--runs from the northwest to the southeast portion. The mountains start near the California border and continue into Guatemala.
The Central Mexican Plateau consumes much of northern and central Mexico. It extends from the border with the USA on the north to the Cordillera Neovolcanica in the south, with the Sierra Madre Occidental mountain range on the west and the Sierra Madre Oriental on the east.he Rio Grande, rising in the San Juan Mountains of the U.S. State of Colorado, flows generally south to the Gulf of Mexico for 1,885 miles (3,000 km) and forms much of Mexico's northern border with the United States.
