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.
The correct answer to this question is this one: they lacked oxygen. The earliest organisms were completely heterotrophic in nature because of the reason that they lacked oxygen. <span>A heterotroph is an organism that cannot fix carbon and uses organic carbon for growth. </span>
Answer:
Embedded in the lipid bilayer are large proteins, many of which transport ions and water-soluble molecules across the membrane. Some proteins in the plasma membrane form open pores, called membrane channels, which allow the free diffusion of ions into and out of the cell.
Answer: Lettuce
Explanation:
Lettuce is a plant, therefore it makes its own food through photosynthesis. Since it does this, we call it a producer or an autotroph.
Answer:
<h2>5.storage of energy</h2>
Explanation:
- Proteins are important biomolecules that are a type of macromolecule.
- This macromolecule is made up of a monomer that is called amino acid.
- There are many functions of the protein molecules in living organisms.
- They play an important role as bodybuilding molecules, as enzymes, as transporter molecules, and many more.
- Most of the enzymes are made up of the protein molecules and regulate the metabolic process of the living organisms.
- Certain proteins are present in the plasma membrane of the cells and play an important role in the transport of the substances across the cells, recognition of certain foreign particles, and some other functions.
- They also play an important role in the immune system.
- The main storage molecules of energy are carbohydrates and fats so storage of energy is not considered as the major function of the proteins because they do not involve as carbohydrates and fats.
