On his trip to the laguna atascosa wildlife refuge, mr Ortiz wants to analyze the overall health of alligator pond. Which of the

VikaD [51]

Answer and Explanation:

To determine the overall health of the alligator pond, Mr. Ortiz should carry out the following tests:

pH level test

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.

Nitrates and Ammonia (NH3) levels

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.

Bacterial coliform test

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.

Is a piece of pottery an example of a fossil? Why or why not?

liq [111]

Your answer is: No.

Although pottery may seem like the same texture of a fossil and could even be formed to look almost identical to one, it will never be a fossil. Fossils come from once living things like dinosaurs, bugs, dead plants...You cannot develop a fossil it will ALWAYS develop itself.

Hope this helps! Would love brainliest if someone else answers! Trying to get to virtuoso thx!

What are the 2 different kind of t-cells and what is their jobs?

motikmotik

The two different kinds of t-cells are the Helper t-cells and the killer t-cells.
T cells are named T cells after the thymus, an organ situated under the breastbone. They are produced in the bone marrow and later move to the thymus where they mature. Helper T cells have a primary tsak of activating the B cells and killer T cells. The killer T cells are specialized in attacking cells of the body infected by viruses and sometimes also by bacteria. Additionally, they can attack cancer cells.

Which is the least number of seismograph stations needed to locate the epicenter of a earthquake

Hunter-Best [27]

At least three seismograph stations are needed to locate the epicenter of a earthquake.

Further Explanation:

An earthquake occurs when two region of the earth slip past each other. Fault plane is the area where the slip occurs. Hypocenter is the region below the earth’s surface where earthquake starts while the epicenter is the region above it.

The earth consists of four major layer:

1. Inner core

2. Outer core

3. Mantle

4. Crust

Seismographs is an instrument used to record the earthquake. The recording done by this instrument is called as the seismograms.

The seismograph comprises of:

1. A base: is fixed tightly in the ground

2. Heavy weight: hangs freely

When the earthquake occurs, the ground shakes and in turn the seismograph also shakes while the hanging weight does not shakes. During the earthquake, the difference in the location between the shaking piece and the motionless piece is recorded. Magnitude of the earthquake is recorded as one for each earthquake. The magnitude of earthquake is measured by the Richter scale but is more commonly measured through moment magnitude scale.
