Explanation:
Writing Dates
There are several correct ways to write dates:
1. In the United States, dates usually begin with the month, followed by the day and the year. Include a comma after the day. If you wish to include the day of the week, place it before the date, followed by a comma.
• December 7, 1941
• January 19, 2015
• Sunday, December 7, 1941
• Monday, January 19, 2015
2. Another style of writing dates puts the day first, followed by the month and the year. Use no punctuation.
• 7 December 1941
• 19 January 2015
3. Dates may also be written using numbers only.
• 12/07/1941 (December 7, 1941)
• 01/19/2015 (January 19, 2015)
Drinking Water Quality
Surface waters and aquifers can be contaminated by various chemicals, microbes, and radionuclides. Disinfection of drinking water has dramatically reduced the prevalence of waterborne diseases (such as typhoid, cholera, and hepatitis) in the United States. Other processes may also be used to treat drinking water depending on the characteristics of and contaminants in the source water.
Common sources of drinking water contaminants include:
Industry and agriculture. Organic solvents, petroleum products, and heavy metals from disposal sites or storage facilities can migrate into aquifers. Pesticides and fertilizers can be carried into lakes and streams by rainfall runoff or snowmelt, or can percolate into aquifers.
Human and animal waste. Human wastes from sewage and septic systems can carry harmful microbes into drinking water sources, as can wastes from animal feedlots and wildlife. Major contaminants include Giardia, Cryptosporidium, and E. coli.
Treatment and distribution. While treatment can remove many contaminants, it can also leave behind byproducts (such as trihalomethanes) that may themselves be harmful. Water can also become contaminated after it enters the distribution system, from a breach in the piping system or from corrosion of plumbing materials made from lead or copper.
Natural sources. Some ground water is unsuitable for drinking because the local underground conditions include high levels of certain contaminants. For example, as ground water travels through rock and soil, it can pick up naturally occurring arsenic, other heavy metals, or radionuclides.
Effects on Human Health
If drinking water contains unsafe levels of contaminants, it can cause health effects, such as gastrointestinal illnesses, nervous system or reproductive effects, and chronic diseases such as cancer. Factors that can influence whether a contaminant will lead to health effects include the type of contaminant, its concentration in the water, individual susceptibility, the amount of water consumed, and the duration of exposure.
Health effects of chemical exposure. Chemical exposure through drinking water can lead to a variety of short- and long-term health effects. Exposure to high doses of chemicals can lead to skin discoloration or more severe problems such as nervous system or organ damage and developmental or reproductive effects. Exposure to lower doses over long periods of time can lead to chronic, longer-term conditions such as cancer. The effects of some drinking water contaminants are not yet well understood.
Health effects of consuming water with disease-causing microbes. Most life-threatening waterborne diseases caused by microbes (such as typhoid fever or cholera) are rare in the United States today. The more common illnesses caused by viruses, bacteria, and parasites can result in stomach pain, vomiting, diarrhea, headache, fever, and kidney failure. Infectious diseases such as hepatitis can also occur. Hepatitis may be severe in people with weakened immune systems (e.g., infants and the elderly) and sometimes fatal in people with severely compromised immune systems (e.g., cancer and AIDS patients).
Answer: Drinking water quality is important for our health. It can be contaminated by different chemicals, microbes, and radionuclides. Thankfully, disinfection has greatly reduced waterborne diseases in the United States. Factors that determine the health effects of contaminants include the type and concentration of the contaminant, individual susceptibility, amount of water consumed, and duration of exposure.
Explanation: 1. Industry and agriculture: Chemicals like organic solvents, petroleum products, and heavy metals from disposal sites or storage facilities can seep into underground water sources called aquifers. Pesticides and fertilizers can also enter lakes and streams through rainfall or snowmelt.
2. Human and animal waste: Harmful microbes can be carried into drinking water sources through sewage, septic systems, animal feedlots, and wildlife. Some major contaminants include Giardia, Cryptosporidium, and E. coli.
3. Treatment and distribution: While water treatment removes many contaminants, it can leave behind harmful byproducts like trihalomethanes. Water can also become contaminated after entering the distribution system, from leaks in pipes or corrosion of plumbing materials like lead or copper.
4. Natural sources: Some groundwater can be unsuitable for drinking due to high levels of naturally occurring contaminants like arsenic, other heavy metals, or radionuclides.
Now, let's explore the effects of drinking water with unsafe levels of contaminants on human health:
1. Chemical exposure: Drinking water with high levels of chemicals can cause short- and long-term health effects. High doses can lead to skin discoloration, nervous system or organ damage, and developmental or reproductive effects. Chronic conditions like cancer can develop from lower doses over a long period of time. However, the effects of some contaminants are still not well understood.
2. Disease-causing microbes: Waterborne diseases caused by microbes are rare in the US, thanks to proper water treatment. However, viruses, bacteria, and parasites can still cause illnesses like stomach pain, vomiting, diarrhea, headache, fever, and kidney failure. Infectious diseases like hepatitis can also occur, especially in people with weakened immune systems.
A.
nervous
B.
depressed
C.
outraged
D.
exhausted
The word which best describes the mood of this passage is:
C. outraged
The person talking is angry because he was betrayed by using false accusations that will cost him imprisonment. He was referring to the handwritten letter which is the item in question as his. The exclamation point also denotes forceful declaration.
b. an intended and recognized consequence of some element of society.
c. a description comprised of the essential characteristics of a feature of society.
d. the meanings that individuals attach to their actions.
The correct statement regarding theory is that, A theory is an explanation of relationships among particular phenomenon. So, the correct option matching the statement is A.
A theory is an explanation of ideas collectively being put together to show the happening or non-happening of an event in a particular way, which may be subjective.
Hence, the correct option is A that a theory can be defined as an explanation of relationships among particular phenomenon.
