Contaminated water is a type of water that is harmful to human beings due to the presence of harmful substances, pollutants, or impurities that make the water unsafe for drinking or other household uses. The characteristics of contaminated water can be identified through various indicators, which can either be physical, biological or chemical.

Physical indicators are visible and may include color, taste, and odor, while biological indicators are not visible and may include bacteria, viruses, and protozoa. Chemical indicators may include heavy metals, pesticides, and organic compounds, among others.

Physical Characteristics: Physical characteristics of contaminated water include cloudy or turbid appearance, unusual taste or odor, or discoloration of the water. The color may range from yellow to brown, blue to green, or even black.

Biological Characteristics: Biological characteristics of contaminated water include the presence of bacteria, viruses, or protozoa. These microorganisms can cause diseases such as diarrhea, typhoid, cholera, and dysentery.

Chemical Characteristics: Chemical characteristics of contaminated water include the presence of heavy metals such as lead, arsenic, or cadmium. Pesticides and fertilizers can also contaminate water and affect human health. Organic compounds like benzene and toluene can also be present in contaminated water, which can lead to health problems such as cancer and nerve damage.

Therefore, it is important to test water sources regularly to identify and monitor any contaminants that may be present. This can help prevent health problems associated with the use of contaminated water.

Answer:

There is no cartilage but there is epithelium

Explanation:

The pharynx of the human respiratory system does not contain cartilage.

The pharynx,  part of the human respiratory system, is a muscular tube that connects the nasal cavity and mouth to the larynx and esophagus. It serves as a passage for  air and food. The gorge is made up of several regions, each with its own distinctive features.

The nasopharynx, the top part of the throat, contains no cartilage. Instead, it is lined with pseudostratified ciliated  epithelium.This special epithelium helps to trap and transport mucus along with any particles or pathogens in the digestive system for elimination.

These regions also lack cartilage but  are lined with  stratified squamous epithelium. This type of epithelium provides protection from mechanical stress and potential abrasion caused by the passage of food and other substances down the pharynx.

The population is not in hardy weinberg equilibrium, because it does not match the previous generation.

The frequency of individuals = individuals/total population

The frequency of Green individuals = 1092/1200

The frequency of Green individuals = 0.91

                                                       q² = 0.91

                                                    √ q² = √0.91

                                                         q = 0.953

By using the first Hardy-Weinberg equation:

                                                                p + q   = 1

                                                                p + 0.953 = 1

                                                                p   = 1 - 0.953

Explanation:

a. By peristalsis

..................

For the word problem, If the difference of a number and the fraction \(\frac{4}{3}\) is \(\frac{11}{3}\), then the number is 5.

The above mathematical problem is a word problem. Word problems are problems that are written in words, rather than in symbols.

To solve for the difference or mystery number, we say, Let x be the number.

The problem states that x -  \(\frac{4}{3}\) =  \(\frac{11}{3}\),

movin -  \(\frac{4}{3}\) to the other side of the equation,

we get x = \(\frac{11}{3}\) + \(\frac{4}{3}\) = \(\frac{15}{3}\)

We solve the fraction by dividing 15 by 3

\(\frac{15}{3}\) = 5

The replacement fertility rate (TFR) in developed countries 2.1 and not 2.0 because "some people get married more than once" (Option B)

The degree of fertility of a woman when she propagates exactly enough girls to replace her in the following generation is referred to as replacement level fertility. It is known as the NRR (Net reproduction rate), and it exclusively counts daughters or female children.

TFR is also used as a measure of replacement-level fertility. It is the average number of offspring required to replace both parents in the next generation. A TFR of 2.1 is considered replacement level fertility in industrialized nations. TFR at the replacement level must be more than 2.0. If TFR is 2.0, which is two children per couple, can you anticipate all female offspring to survive until they reach childbearing age? No, TFR must be more than 2.0.

Furthermore, the sex ratio at birth has consistently favored boys, with 105 boys born for every 100 females. After accounting for all of these variables, the replacement level of fertility is 2.1.

The flexibility of spider silk determined by the structure of its molecules is quite strong.

The components that make up spider silk are what give it its flexibility. Proteins called fibroins, which are made up of amino acids organised in a certain sequence, make up spider silk. The arrangement of amino acids in fibroin proteins results in a helical structure, which is held together by hydrogen bonds between the amino acids.

The fibroin protein chain's exact arrangement of amino acids and hydrogen bonds produces a special blend of strength and flexibility. The silk is flexible enough to stretch and absorb energy without breaking and robust enough to resist significant stress. Spider silk is a fantastic material for many uses, including clothes, medical equipment, and even bulletproof vests, thanks to its unique mix of qualities.
