Acid rain is a combination of rain, snow, dust, and other particles with a ph lower than 5.6.
The acid rains occur when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and with the help of the winds and air currents that transport them. The sulfur dioxide and nitrogen oxides react with oxygen, water, and other chemicals, and they form sulfuric and nitric acids.

The bacteria, Angelinus ballerinea secretes a compound that inhibits the growth of other Gram-positive bacteria. Scientists take this compound and add chemical groups to it to make it more stable for use in humans to treat bacterial infections. This is an example of antibiotic.
<h3>
What is antibiotic?</h3>
- Antibiotics from the key class of glycopeptides can stop this process.
- Through five H-bonds, these antibiotics bind to the C-terminal d-Ala-d-Ala of the murein precursor, lipid II, and immature peptidoglycan, preventing transglycosylation and/or transpeptidation during the production of the cell wall.
- Contrarily, antibiotics have easier access to the thick, porous peptidoglycan layer in the cell walls of Gram-positive bacteria, allowing them to more easily enter the cell and/or interact with the peptidoglycan itself.
- The two main antibiotics that prevent the synthesis of bacterial cell walls are penicillins and cephalosporins.
- Penicillin is one of many antibiotics that assault the bacterial cell wall in order to operate.
- The medications specifically stop the bacteria from producing peptidoglycan, a chemical that gives the cell wall the toughness it needs to live in the human body.

Answer:
Environmental awareness is an incredibly important part of our lives. In order to protect the sustainability of the planet, everyone needs to commit to becoming more environmentally aware. Environmental degradation is detrimental and is jeopardising the long-term health and security of animals, plants and humans.

50-70%. At the age of 1, percentage is around 65%. In adult men, 60% of their bodies is water. 55% of adult women's weight is water due to fat not holding as much water as lean tissue; fat makes up more of women's bodies than men.
