Answer:
The correct option is E) Contraction still occurs because Ca2+ can enter the cell directly through Ca2+ channels in the plasma membrane and bind to calmodulin.
Usually, the calcium ions are released from the sarcoplasmic reticulum of a cell during a muscle contraction, but if those are blocked, the contractions is an cell can still arise through the calcium ions which are present in the cell membrane of a cell. 
 
        
             
        
        
        
Answer:
- Both processes form minerals.
- Volcanic eruptions form precipitates and shifting of tectonic plates form minerals.
Explanation:
Both volcanic eruptions and the shifting of tectonic plates form minerals. Volcanoes and their eruptions can directly or indirectly lead to the formation and/or deposit of minerals such as diamonds and zinc. Shifting also forms minerals due to the forces of compression the plates apply on each other as they move past. 
Volcanoes are known the cause precipitates because when the erupt, the ash that is released mixes with water vapor which then becomes rain eventually.
