One of the main water lines supplying the houses in a town has broken and everyone was told to boil their drinking water until t
he water supply has been retested and found safe. If some of the people choose to drink the water without boiling it first, how might their health be affected? A.They might get infected with living organisms that could make them sick.
B.Any heavy metals that got into the water could cause birth defects in their children.
C.The silt in the water could be carrying fertilizer residue that could kill them.
D.They could potentially develop cancer if pesticides got into the water.
Water is the most important element in our body and we need a constant supply of it to survive. Now in the scenario that you described is very important to make sure you boil the water because that is the best way to ensure that you killed any living organism (Virus, bacteria or parasites) that could endanger your life. So the answer to your question is A as it was said before but let me elaborate a little more.
Explanation:
Many times, water is contaminated by mosquito or bacteria that can cause among other problems Dysentery. This is an inflammation of the intestines that cause a lot of pain and a bloody diarrhea. This bacteria is spread through water or food and in many third world countries is the main cause of death among the population. When you boil the water the bacteria is killed and the water is safe for drinking. If you ever learn of someone developing such symptoms and they claim to have drank unsafe water, suggest them to go to the doctor intermediately. Their life is at risk.
A woman with blood type A has a child with blood type O. She accuses a man who is homozygous for blood type B of being the father. Could this man be the father of her child? If so, what is the chance he is the father?
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. ... These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
The reason both of these are valid scientific hypotheses is because A) scientists with different educational backgrounds may put forth different hypotheses to explain the same data. This approach in science is vital in making progress and has helped to explain many phenomena in the past. When scientists explain data using different approaches, they come to a more comprehensive conclusion.
