The cells, organelles, and the tissues of the body are measured in micrometers. The size of the cells, tissues, and various organelles are very small. Majority needs the help of microscope to be seen. Therefore, the larger units of the metric system cannot be used to measure their sizes. Hence, the smaller unit, such as the micrometer is used for their measurement purpose.
The given blank can be filled with micrometers.

The overwhelming amount of seismic activity particularly happens along convergent plate boundaries. In particular, reverse or thrust faults occurs on convergent plate boundaries.Converging plate boundaries are classified into two types of activities.First is the subduction boundary where the oceanic lithosphere is pressured beneath a continental plate or oceanic plate thus it overrides the other plate then slowly directed to the mantle where it will become a magma. Second is the collisional boundary where earthquakes occur because of the continental crust squeezed together then plates are pushed upwards.Reverse faults are correlated to earthquakes with magnitude of 8 or more.Hence, earthquakes of magnitude 8 or more are considered powerful and mega thrust earthquakes.</span>
Answer:
The policy for controlling environmental mercury pollution should address ways to prevent and control this pollution. Policy:
- Ban the incineration of waste
- Require that coal-burning companies remove mercury from the coal
- Allocate funds towards research and development for renewable energy resources in the hopes of switching away from coal.
- Require that products containing mercury be labeled as such.
- Set up programs that will recycle batteries and mercury-filled products.
- Set up education programs that will help inform people about mercury pollution.
This policy works by addressing the ways to prevent and control mercury pollution.
Three problems that could result from implementing this policy:
- Backlash from coal-burning companies.
- It could take a while before we completely shift away from using coal.
- Some of the programs that can be set up in this policy can be too expensive to set up and maintain.
