Name three major types of water pollutants, and provide an example of each. explain which classes of pollutants you think are most important in your local area.

Answers

Answer 1
Unwanted substances present in water are called water pollutants that cause water pollution. Water pollutants can be of various types such as:
1. Suspended matter pollutants: These are the water pollutants present on the surface of water. These pollutants do not dissolve in water and are found suspended in water. For example, Plastic bags and other plastic products.
2. Chemical pollutants: Metals and solvents from the industries and factories flow in the water bodies and pollute them.For example, pesticides, etc.
3. Microbiological pollutants: These pollutants include bacteria, fungi, algae, etc. Some of these microflora are naturally present in the water and do not cause harm but if their number increases dramatically it affects human health if drunk without treatment.

I think, in my area due to the presence of industries, chemical pollutants are more profound that also leads to the depletion of oxygen in water by increasing the Chemical oxygen Demand (COD). It adversely affects the aquatic living organisms.

Is it conceivable that these two reagents would react with each other? what experimental evidence do you have to support your answer?

Answers

Under controlled conditions, sodium bromide and hydrogen peroxide are actually able to react. However in this experiment, I do not believe that they would react. This is due to the presence of other compounds which are used in the reaction and the means by which the compounds were added to the solution. There are actually a few clues that can tell us whether they are reacting. The most obvious one is that there would be bubbling due to production of H2 gas.

Most people think babies are equally likely to come as either a boy or a girl. this is not true. actually, about 51.3% of all babies are boys. if a family has two children (not twins), what is the chance they have one boy and one girl? round your answer to two decimal places.

Answers

49.97% For this problem, let's consider the probability of each of the four possibilities for having two children, being BB, BG, GB, and GG. Then sum the probabilities for both the BG and GB events. So BB = 51.3% * 51.3% = 26.3169% BG = 51.3% * 48.7% = 24.9831% GB = 48.7% * 51.3% = 24.9831% GG = 48.7% * 48.7% = 23.7169% If you check, you'll notice that the sum of all the probabilities add up to 100% like it should. And the sum of BG + GB is 24.9831% + 24.9831% = 49.9662% which when rounded to 2 decimal places is 49.97%

The _____ law of thermodynamics states that energy can't be created or destroyed. Two natural sources of energy on Earth are the _____.


A. first, Sun and core of Earth
B. second, Sun and rock
C. second, Sun and biosphere
D. third, core of Earth and hydrosphere

Answers

the correct answer to your question is A, first, sun and core of the earth I hope this helps you out, let me know if its right. Im 100% I am. 

Answer:

Option A, first, Sun and core of Earth

Explanation:

According to first law of thermodynamics,  

An energy can never be created nor destroyed, it can only be converted from one form to other and therefore the first law of thermodynamics is known as law of conservation of energy.  

There are only few energy sources for planet earth – Solar energy, gravity, rotation of earth and radioactive energy

Solar energy is the prominent source of energy that drives several natural process like winds, hydrologic cycle, biosphere ecological cycle , and also derives the overall climate system . While the earth core causes gravitational force which is very essential for several natural process like rotation, tides, etc.

How many moles of O2 are required for the complete reaction of 88.9 g of C2H4 to form CO2 and H2O?

Answers

The molecular mass for C2H4 should be: 2*12 + 4*1= 28 gram/mol. Then the amount of mol in 88.9 grams C2H4 should be: 88.9g/ (28g/mol)= 3.175 mol.

To answer this question, you need to know the reaction formula for the problem. The formula should be: 
C2H4 + 3O2 --> 2CO2 + 2H2O 
In the formula, every 1 C2H4 will be reacted with 3 O2. Then the amount of oxygen needed would be: 3/1 * 3.175 mol= 9.525 mol

Major factors that determine a population's growth rate

Answers

The main factor that determines a populations growth rate is the availability of resources. Other factors can contribute, such as competition for food, disease, weather, immigration/emigration, birth/death rate, etc.

Final answer:

The population growth rate is influenced by birth rates, death rates, immigration, and emigration. The equation to calculate growth rate is growth rate = birth rate – death rate. Economic growth is also related to population growth, as labor demands affect GDP and standards of living.

Explanation:

Major Factors Determining Population Growth Rate

The growth rate of a population is primarily determined by four key factors: birth rates, death rates, immigration, and emigration. If the birth rate exceeds the death rate, the population increases. Conversely, if the death rate is higher than the birth rate, the population size will start to decline. When birth and death rates are equal, the population size remains constant. Additionally, populations gain individuals through immigration and lose individuals through emigration.

Furthermore, population growth can be calculated using a simple formula: growth rate = birth rate – death rate. This equation highlights the importance of fertility rates, life expectancy, and net immigration levels, which are also considered by demographers when studying population characteristics. Populations do not always grow continually; growth depends on various factors, including the average age of individuals within the population, local economic conditions, and availability of resources such as food, moisture, and oxygen.

When discussing population growth and economic growth, the labor market and population size are crucial since they influence the Gross Domestic Product (GDP) and, consequently, the standard of living. As the economy grows, more labor or increased labor productivity is necessary to meet consumer demands. Countries with smaller, well-managed populations often enjoy higher standards of living than overpopulated ones. Thus, population growth rates have a direct impact on economies locally and globally.

Answers

The nurse should calculate the correction dose the patient should take.

Correction dose = [actual(144mg/dl) - target blood glucose(100mg/dl in a fasting situation)] ÷ correction factor(50) <=>

Producing cartilaginous matrix.

The presence of chondrocytes indicates that a tissue is producing cartilaginous matrix.

What are the functions of chrondocytes?

Chondrocytes are the cells responsible for cartilage formation, and they are crucial for the process of endochondral ossification, which is useful for bone development. Also, by mimicking skeletal development chondrocytes play a critical role in fracture repair.

Chondrocytes are mainly responsible for the production of collagen and the extracellular matrix that will lead to the maintenance of cartilaginous tissues within joints. Initial cartilage is composed of the mesenchyme during the fifth week of development.

Chondrocytes arise from cranial neural crest cells (CNCCs) of the neural ectoderm, cephalic mesoderm, sclerotome of the paraxial mesoderm, or somato-pleure of the lateral plate mesoderm.
