Explanation:
Many invertebrate animals cant survive in water that has been polluted and resulted in a lowering of oxygen concentration so the presence or absence indicates the extent to which a body of water is polluted.
Lichens can be used to indicate air pollution as they grow exposed to places such us rocks and tree barks. They need to be efficient at absorbing water and nutrients to grow there. Rain water contains enough nutrients to keep them alive. Air pollutants dissolve in rain water especially sulfur dioxide can damage lichens and prevent them from growing. This makes them a natural indicator of air pollution.
When we want to get a bacterium to make a chemical normally made by a human, we take the gene from the human and put it into the bacterium by using a bacterial enzyme known as <u>DNA ligase</u>
<h3>What is are bacteria?</h3>
Bacterial are microscopic unicellular organisms which are made of prokaryotic cells. They reproduce asexually.
Some bacteria which are saprophytes; organisms which feed on dead and decaying organisms while some bacteria are parasites.
So therefore, when we want to get a bacterium to make a chemical normally made by a human, we take the gene from the human and put it into the bacterium by using a bacterial enzyme known as <u>DNA</u> <u>ligase</u>
