On his trip to the laguna atascosa wildlife refuge, mr ortiz wants to analyze the overall health of alligator pond. which of the tests should he perform?

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.

pH is acceptable in a range of 6.5 to 8.2.

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.

Over 0.2 per L could be lethal to some fish species that are also important for the health of the alligator pond.

Less than 0.1 indicates a healthy alligator pond.

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 less than 10 fecal coliform bacteria/100 mL.

i was told this before by a teacher, so yeah

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
