Which of the following is typically associated with a large amount of organic material in a water supply?
Lower turbidity
Higher phosphates
Fecal coliform
High dissolved oxygen
is it c pls help
It is C , yes.
Took u 4 years to answer. Test is probs done by now lol.
To determine which of the given options is typically associated with a large amount of organic material in a water supply, we can analyze each option.
1. Lower turbidity: Turbidity refers to the cloudiness or haziness of water caused by suspended particles. Higher turbidity levels often indicate a higher concentration of suspended particles, including organic matter. Therefore, lower turbidity levels are associated with lower amounts of organic material in the water supply.
2. Higher phosphates: Phosphates are compounds that contain the element phosphorus and can be found in various water sources. While higher levels of phosphates can contribute to the growth of algae and aquatic plants, they are not specifically indicative of the amount of organic material in the water supply.
3. Fecal coliform: Fecal coliform is a group of bacteria that originates from the intestines of warm-blooded animals, including humans, and is often used as an indicator of fecal contamination in water. Its presence does suggest the presence of organic material, particularly from fecal matter.
4. High dissolved oxygen: Dissolved oxygen refers to the amount of oxygen gas dissolved in water and is necessary for the survival of aquatic organisms. While high dissolved oxygen levels are generally indicative of good water quality, they do not directly relate to the amount of organic material present in the water supply.
Based on the analysis, the option "Fecal coliform" is the most closely associated with a large amount of organic material in a water supply. Therefore, the correct answer is "C."
Remember, understanding the principles and concepts related to water quality, such as turbidity, phosphates, bacteria indicators, and dissolved oxygen, can help in answering similar questions in the future.
