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:
Disruptive selection
Explanation:
Disruptive selection, also known as diversifying selection, describes changes in population genetics where extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups. In this more individuals acquire peripheral character value at both ends of the distribution curve.
Fungi is more closeley related to animals than plants, because fungal cells are organized into tube-like filaments called hyphae. Hyphae are surrounded by a cell wall, and grow from the tips. This cell organization is very similar to that of an animals.
Answer:
I hoped this helped
Explanation:
Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA).Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins.Lastly, termination occurs when the ribosome reaches a stop codon (UAA, UAG, and UGA). Since there are no tRNA molecules that can recognize these codons, the ribosome recognizes that translation is complete. The new protein is then released, and the translation complex comes apart.
