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.
Because Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. Activities that remove vegetation, disturb the ground, or allow the ground to dry are activities that increase erosion.
Answer: Viruses, although not living things, do show some characteristics that they are living. Because they can't reproduce by themselves (without a host), viruses are not considered living. They are made of proteins and glycoproteins like cells are. They contain genetic information needed to produce more viruses in the form of DNA or RNA.
They are acellular, that is, they contain no cytoplasm or cellular organelles. They carry out no metabolism on their own and must replicate using the host cell's metabolic machinery.
