Answer;

-All of the above

-pathogens, disease vectors, and high levels of contaminants

Explanation;

Water pollution is a large set of adverse effects upon water bodies (lakes, rivers, oceans, groundwater) caused by human activities. Water pollution is caused by;

  • Increases in nutrient loading may lead to eutrophication.
  • Organic wastes such as sewage and farm waste impose high oxygen demands on the receiving water leading to oxygen depletion with potentially severe impacts on the whole eco-system.
  • Industries discharge a variety of pollutants in their wastewater including heavy metals, organic toxins, oils, nutrients, and solids.
  • Discharges can also have thermal effects, especially those from power stations, and these too reduce the available oxygen.

scZoUnD [109]

Answer:

Repolarization

Explanation:

Repolarization refers to the phase during which the resting potential is restored after depolarization. This means that the inside of the axon membrane becomes negative again compared to the outside.

Repolarization is obtained by the functioning of K+ ion channels. The opening of K+ ion channels allows the K+ to move outside of the axon. Movement of positively charged ion (K+) outside of axon makes the inside negative again and the resting potential is restored.

They can first charge individuals to use the services. For example, similar to 23andme or Ancestry, who provide a service of telling you interesting things related to your health or ethnicity.

They could also sell that data to pharmaceutical companies or other research groups who can use the DNA information for research. The more samples of DNA we have sequenced, the more information scientists have to work with and design drugs and more.
