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.
3. Temporarily inactive: a dormant volcano. 4. Being in a condition of biological rest or inactivity characterized by cessation of growth or development and the suspension of many metabolic processes: a dormant bud; a dormant bacterium.
A dormant volcano or sleeping volcano is a volcano that has been quiet for a long time, but still has signs it may erupt again. A volcano becomes dormant when the vent is blocked by hardened lava, called a plug, or if the magma seeps back under the earthâs crust. Volcanoes can be dormant for hundreds of years.n practice, it is often impossible to distinguish between a dormant and an extinct volcano and several volcanoes thought to be extinct have subsequently re-erupted. Volcanoes can be dormant for hundreds or thousands of years and, due to the lack of eruptions, are usually eroded and worn down.
