7 0

Answer:

Zero Turbidity

Explanation:

High phostphate levels cause excessive algea growth and a decreased level of dissolved oxygen. High levels of nitrates are caused by animal or human waste and the overuse of chemical fertilizers. Low turbidity causes the water to be more clear so zero turbidity is the only right answer. I got it right on my test too

Soils contain small or trace amounts of many minerals, including the chemical elements phosphorus, calcium, potassium, magnesium
serg [7]

Answer:

Magnesium, calcium, phosphorous, sulfur these are essential nutrients for plants. These are required in trace quantity but are very important for plant life. Point A. will be correct answer.

Explanation:

As in B. starch n cellulose are composed of only carbon, oxygen and hydrogen.

As in C. These elements are not required on special occasion but are necessary throughout plant life.

As in D.  C H N O  is the primary component plants need but these secondary nutrients are equally necessary for growth n structure of plant.

<u><em>So answer A. Is the correct option.</em></u>

Calcium plays the most important role in structure formation of plants. Also act as messenger molecule in signaling. Deficiency  of calcium caused wilting , weakened stem and ultimately death of plant.

Magnesium is the key element in chlorophyll molecule. It is necessary for chlorophyll formation.

Sulfur is another very important element in plant life, it is necessary for protein synthesis in plants.

Phosphorous plays an important role in  process of cell devision , photosynthesis and respiration.

Potassium is very crucial in gaseous exchange ,it operates the opening and closing of stomata.

For several years,researchers have atempted to produce AB artificial blood for transfusions. Artificial blood would most likely
Yuliya22 [10]

Answer:

It is a good concept but can't be used.

Explanation:

Producing artificial blood is a good concept but it can't take the place of real human blood because the artificial blood has many disadvantages which can cause great damage to our body such as binds nitric acid that affected blood flow, increases the level of bilirubin, amylase and lipase in the blood and also cause overload of iron in your organs or tissues so that's why it can't be used instead of original human blood but may be in the future if these complications are removed.

The image below shows a convergent plate boundary.
JulsSmile [24]

Answer:

the answer is volcanoes

Explanation:

The oceanic crust collides with the continental crust to form a convergent boundary. At the convergent boundary, the denser oceanic crust sinks under the lighter continental crust. The rocks of the oceanic crust reach very high temperatures of about 12,000°C, which is enough to melt the rocks. These molten rocks travel upward through cracks and crevices in the continental crust. They then erupt on the surface as volcanoes. Therefore, the feature expected to form at point X as the result of converging plates would be volcanoes.

Trace the ductal pathway from the epididymis to the urethra. (Module 26.5C)
iragen [17]

Answer:

epididymis

ductus deferens

ampulla of ductus deferens

seminal gland

ejaculatory duct

urethra

Explanation:

Epididymis is a tube that connects the back side of the testicles to the vas deferens (ductus deferens). The vas deferens is the connecting link between epididymis and urinary tract/urethra and is responsible for transporting sperm to the urethra. Seminal vesicles are small glands that lie above the prostate gland and make up more than 50% of the total semen. Seminal vesicles are connected to the vas deferens through ejaculatory duct. This duct empties sperm and semen into the urethra

Hence, the correct order is

epididymis

ductus deferens

ampulla of ductus deferens

seminal gland

ejaculatory duct

urethra
