how can you detect hardness of water collected from different sources​

Answers

Answer 1
We can detect the hardness of water taken from different sources by adding soap to it. If the soap does not form micelle in the water then it will be hard water. In simple language if the soap doesnot disslove in water then it will be soft water.

Define nondisjunction. Is this a beneficial process? Explain.

Answers

Answer:

Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division (mitosis/meiosis). There are three forms of nondisjunction: failure of a pair of homologous chromosomes to separate in meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during mitosis. Nondisjunction results in daughter cells with abnormal chromosome numbers (aneuploidy).

Residents of an older building have children with a higher incidence of developmental delays. Which of the following is a possible cause of the developmental issues?

Old lead pipes are still used in the building.
Asbestos was not removed from the building.
The heating system is releasing carbon monoxide.
Pesticides were used in the building's landscaping.

Answers

Answer:

A

Explanation:

I took the test :)

Primitive lead pipes still in use in the construction may be the root of the building's developmental issues. So, the correct option is A.

What are Lead pipes?

Long lead pipes are recognised as the main source of lead in drinking water, lead service lines are the pipes that transport water from the underground water main to homes.

Remember that lead has been used in water pipes for thousands of years. Ancient civilizations picked lead for piping because it could withstand tiny leaks and was pliable enough to form into efficient water-delivery designs.

The development problems with the building may be caused by the outdated lead pipes that are still being used in the construction.

Thus, the correct option is A.

how does flouride cause kidney deasies

Answers

Answer:

Hepato- and nephrotoxicity of fluoride have been demonstrated in animals, but few studies have examined potential effects in humans. This population-based study examines the relationship between chronic low-level fluoride exposure and kidney and liver function among United States (U.S.) adolescents. This study aimed to evaluate whether greater fluoride exposure is associated with altered kidney and liver parameters among U.S. youth.

This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (2013–2016). We analyzed data from 1983 and 1742 adolescents who had plasma and water fluoride measures respectively and did not have kidney disease. Fluoride was measured in plasma and household tap water. Kidney parameters included estimated glomerular filtration rate (calculated by the original Schwartz formula), serum uric acid, and the urinary albumin to creatinine ratio. Liver parameters were assessed in serum and included alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, blood urea nitrogen, gamma-glutamyl transferase, and albumin. Survey-weighted linear regression examined relationships between fluoride exposure and kidney and liver parameters after covariate adjustment. A Holm-Bonferroni correction accounted for multiple comparisons.

The average age of adolescents was 15.4 years. Median water and plasma fluoride concentrations were 0.48 mg/L and 0.33 μmol/L respectively. A 1 μmol/L increase in plasma fluoride was associated with a 10.36 mL/min/1.73 m2 lower estimated glomerular filtration rate (95% CI: −17.50, −3.22; p = 0.05), a 0.29 mg/dL higher serum uric acid concentration (95% CI: 0.09, 0.50; p = 0.05), and a 1.29 mg/dL lower blood urea nitrogen concentration (95%CI: −1.87, −0.70; p < 0.001). A 1 mg/L increase in water fluoride was associated with a 0.93 mg/dL lower blood urea nitrogen concentration (95% CI: −1.44, −0.42; p = 0.007).

Fluoride exposure may contribute to complex changes in kidney and liver related parameters among U.S. adolescents. As the study is cross-sectional, reverse causality cannot be ruled out; therefore, altered kidney and/or liver function may impact bodily fluoride absorption and metabolic processes.

if temperature were available from several stations in canada near the great lakes do you think 15-degree line would form a closed loop?

Answers

Yes, a 15-degree line would form a closed loop for temperature obtained from several stations in Canada near the Great lakes.

What is temperature?

Temperature refers to a measure of the degree of hotness or coldness of a physical body (object). Also, temperature is typically measured by using a thermometer and its units are:

Celsius (°C)Kelvin (K)Fahrenheit (°F)

What is an isotherm?

An isotherm can be defined as a line that is drawn on a map to join points with the same temperature, so as to show the distribution of temperature in a geographical region on Earth's surface.

In Meteorology, a closed loop is used to show or depict where an air mass is located when drawing isotherms. Thus, a 15-degree line would form a closed loop for temperature obtained from several stations in Canada near the Great lakes.
