Human evolution known to be a process in which species adapt to certain conditions of life, and in the battle of life and death, they are forced to become stronger in order to survive in this world. Diseases have always been present during the evolution, acting themselves as a natural selectors - the weaker organisms get sick and die. Not just humans, but all species have to establish a great protecting mechanism in order to survive. That is how our bodies are built, to be able to withstand and survive in the conditions we live in, and that is why our immune system has to be taken care of.
Hope this helped :)
Answer:
By reducing the emission of CFC's gases.
Explanation:
The Greenpeace organization monitoring the situation with ozone by reducing the emission of CFC's gases that causes depletion of ozone layers. This organization reduces the use of fossil fuels and promoting renewable energy in order to prevent changes in the climate. The Greenpeace organization ensures the use of those machines which can't produce CFCs and HFCs because one chlorine which is present in these gases destroys 100000 ozone molecules.

<h3><u>Answer and explanation;</u></h3>
- DNA is a double stranded molecule. Covalent and hydrogen bonds pray important roles in the functioning of DNA molecules.
- <em><u>Covalent bonds occur within each linear strand and strongly bond the nucleotide bases, sugars, and phosphate groups occurring both within each component and between components.</u></em>
- <em><u> Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.</u></em>
- Hydrogen bonds helps the complementary base pairs in DNA; guanine with cytosine and adenine with thymine to connect to one another. The hydrogen bonds between these complementary pairs helps keep the two strands of DNA helix together.
Answer:
They both convert kinetic energy to electrical energy
