Its important because it tells us the difference between populations and individuals
If a hypothetical poison prevent nucleoli from carrying out their functions, the cell organele that will be affected is the RIBOSOMES.
Nucleoli of the cell is the one that is responsible for production of ribosomal sub units; it uses proteins and ribosomal RNA to do this. It then send the sub units to the interior of the cell where they are assembled.
Ribosomes make proteins in the cells. Thus, if nucleoli is affected, ribosome will not be produced and ultimately proteins will not be produced in the cells.
The viscosity of magma is determined by its silica content.
Basalt magma, on the one hand, which is often
of low viscosity, has a low silica content of approximately 50% or less. Rhyolite magma, on the other hand, has high viscosity due to the high silica content of
approximately 70% and more.
Gas content and temperatures of the magma are the other factors
that determine an explosive or
nonexplosive eruption. High temperatures
and high gas content (coupled with high viscosity)
cause violent explosions.
mechanical weathering
Mechanical weathering is the process of breaking big rocks into little ones. This process usually happens near the surface of the planet. Temperature also affects the land. The cool nights and hot days always cause things to expand and contract. That movement can cause rocks to crack and break apart.Mechanical weathering involves mechanical processes that break up a rock: for example, ice freezing and expanding in cracks in the rock.
