Answer and Explanation:
To determine the overall health of the alligator pond, Mr. Ortiz should carry out the following tests:
pH is extremely important in this type of research as a reduction of pH could lead to a higher availability of toxic metals that may be absorbed by aquatic organisms such as alligators and fish species.
<em>pH is acceptable in a range of 6.5 to 8.2.</em>
- <u>Nitrates and Ammonia (NH3) levels</u>
Oversaturation of nitrates and ammonia could lead to the death of organisms that are crucial for the maintainance of a healthy pond and for the balance of the food chain.
Moreover, it could lead to algal blooms that result in a lower concentration of oxygen available for other organisms.
<em>Over 0.2 per L could be lethal</em> to some fish species that are also important for the health of the alligator pond.
<em>Less than 0.1 </em>indicates a healthy alligator pond.
- <u>Bacterial coliform test</u>
This test determines the amount of bacteria that comes from waste (animal or human), which could lead to mild to serious bacterial infections and diseases.
If it is a healthy pond, the results should indicate <em>less than 10 fecal coliform bacteria/100 mL.</em>

Answer:
Option). It permits hydrogen bonds between DNA strands to dissociate.
Explanation:
PCR (polymerase chain reaction) techniques can bed defined as a technique, which is used for in vitro amplification of sample DNA. It is made up of three steps, denaturation, primer annealing, and extension.
The first step in PCR is heating of sample DNA to denature the double stranded DNA by breaking hydrogen bonding present between bases of double stranded DNA.
Due to this, double strands of DNA get separated and provide templates for synthesis of daughter DNA strands.
Thus, the correct answer is second option.
