The statement water is easily polluted..... is true. Water is pretty much the world's best solvent. So even toxic substances are easily dissolved in it and when that happens they pollute the water.

Answer: Water is easily polluted because it can dissolve harmful chemicals.

Water is capable of dissolving a variety of different substances in it, hence, it is called as universal solvent. It exhibit a polar arrangement of two elements named as hydrogen and oxygen. The hydrogen has positive electrical charge whereas the oxygen has negative electrical charge. This polarity is responsible for attracting different types of molecules. Hence, favors dissolution in water.

Therefore, water is easily polluted because it can dissolve harmful chemicals is the correct option.

A standard PCR cycle includes three steps: denaturation (95°C), annealing (55°C), and elongation (65°C).
xz_007 [3.2K]

Answer:

Denaturation process: The DNA template  

Annealing process: Primers  

Elongation process: dNTPs and Taq polymerase

Explanation:

For the denaturing process, the only ingredient that is required is the DNA template that will be separated from a double helix (or double strand) into a single strand, by increasing the temperature to 95 C, (at this temperature the hydrogen bonds that keep together the double stranded break). After the double strand is denatured, the following process is annealing. For this, the required ingredient are the primers; these primers will hybridize or anneal according to the nucleotide complementarity to the single strand of the DNA. Finally, for the Elongation process, you will require the Taq polymerase and the dNTPs. The enzyme will synthesize or “generate” a new strand of DNA based on the DNA template, using the provided dNTPs in the direction 5’ to 3’.

I hope this clarify you inquiry.

Calculate the volume of 1 M NaOH needed to prepare 12.0 mL of a 0.10-M solution. Prepare this solution. (Refer to the Dilutions
Lapatulllka [165]

Answer:

1.2 mL

Explanation:

<em>This is a problem of simple dilution. The dilution principle simply agrees that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Recall that: number of moles = mass/molar mass or molarity x volume.

Hence, for the dilution principle:

              initial molarity x initial volume = final molarity x final volume.

In this case, initial molarity of NaOH = 1 M, initial volume = ?, final molarity = 0.1 M, final volume = 12.0 mL.

Initial volume = final molarity x final volume/initial molarity

                       = 0.1 x 12/1 = 1.2 mL

It thus means that 1.2 mL of 1 M NaOH would be taken and then diluted up to 12.0 mL mark by the addition of distilled water in order to produce 12.0 mL, 0.10 M NaOH solution.

Whatr is the function of autotropns in the carbon cycle
bija089 [108]

Answer:

The biological carbon cycle

Autotrophs capture carbon dioxide from the air or bicarbonate ions from the water and use them to make organic compounds such as glucose. Heterotrophs, or other-feeders, such as humans, consume the organic molecules, and the organic carbon is passed through food chains and webs.

Through which conversion is energy released?
Stels [109]

Answer: B) ATP to ADP

This reaction is termed as ATP hydrolysis.

ATP ( adenosine triphosphate) conversion to ADP ( adenosine diphosphate) is an energy producing reaction ( exothermic reaction). ATP contains high energy bonds called phosphoanhydride bonds. Thus, when this bond is broken down, ATP is converted to ADP and Pi ( inorganic phosphate) and  releases large amount of energy.
