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.
One of the simpler ways to answer is that an active volcano is one that has erupted since the last ice age (i.e., in the past ~10,000 years). That is the definition of active used by the Global Volcanism Program in their catalogs. A dormant volcano would then be one that hasnât erupted in the past 10,000 years, but which is expected to erupt again. An extinct volcano would be one that nobody expects to ever erupt again. These are human definitions of natural things â there have been a number of eruptions from âextinctâ volcanoes!
