Answer:
If the oil spilled in the gulf would have been processed oil, it would be worse than a normal oil spill as these oils have a higher shelf life.
Explanation:
Oil spills happen when a large quantity of oil gets mixed with large water bodies like <em>sea and oceans</em>. The oil being denser than water floats on the surface and does not mix with the water. It forms a coating on top of the water.
The difference between processed oil and normal oil is that they are heated at very <u>high temperatures</u> and this results in oxidation which creates <em>free radicals</em>, which are not good for the body and its cells. Also they have a very long shelf life due to which they will remain on water for a long time.
When oil spills happen, the <em>wind</em> cause the spill to spread over the water surface, thereby engulfing a large amount of area. The major disadvantages of the spill are:-
- The oil gets stuck in the feathers of the birds who come by to dip themselves,
- Animals like whale, dolphins have blow holes for releasing water. the oil covers these holes and makes it difficult for them to breathe.
- The fur of animals like <u>seal and otter </u>gets mixed with the oil and can prove harmful to them as it gets them exposed to cold.
- The overall BOD of the water body decreases, and organisms which use sun rays coming inside the ocean suffer as these get blocked.
- Since processed oil has longer shelf life, a large quantity of animals will suffer and die.
Connecting the worlds of engineering and regenerative medicine is no small feat and I hope that our last blog, which connected the human brain and the controller of an automation system, opened your eyes and allowed you to make some realistic associations between two distinct processes. With these blogs, we are propelling the industry forward by familiarizing both engineers and scientists with the worlds of a “different” industry.

Answer: B. Water breaks down into oxygen molecules for respiration.
Water is the required for photosynthesis, a process by which plants (terrestrial and aquatic) makes their food by utilizing water as a reactant to produce oxygen and glucose as product. The glucose act as a source of energy for conducting various metabolic processes in plants but oxygen is released in the air.

This oxygen is necessary for terrestrial and aquatic animals for respiration. Therefore, water breaks down into oxygen by the process of photosynthesis, hence water plays important role in respiration in living beings.
Answer: Diagnosis: The presence of nitrites in the urine confirms the urinary tract infection.
Explanation:
Treatment: The urinary tract infection will be concerned with the antibiotic therapy to kill the bacteria producing excess nitrites. Educating K.N. about the risk factors associated with the multiple sex partners and transfer of bacteria through sexual contact.
Use of fluroquinolones and nitrofurantoin:
Fluroquinolones: This is an antibiotic which has bacteriocidal property can be useful in the treatment of urinary tract infections.
Nitrofurantoin: It is an effective antibiotic in killing bacteria it gets activated inside the bacteria.
Nitrituria is a condition in which the nitrites are present in the urine that is indicative of the presence of bacterial infection. It is caused by the <em>E. coli</em> bacteria inside the urinary tract. It is responsible for converting the nitrates into nitrites.
