What conditions make for a violent volcanic eruption?
OA. Magma with low gas content
OB. Magma with low viscosity
OC. Magma with high silica content
OD. Magma that can flow easily

Answers

Answer: B

Explanation:

Magma with low viscosity

Magma that has high content of silica will lead to a violent volcanic eruption. Thus, the correct answer is option C.

What kind of magma results in violent volcanic eruption?

Magma that has a high content of silica will have high viscosity. This is due to the bond formation between silicon and oxygen, forming a Si-O tetrahedron.

These tetrahedra combine with each other and result in polymerization which increases the resistance of the liquid to flow. This type of thick magma does not flow easily and will result in an explosive eruption.

High amount of silica causes a lot of gas to be trapped in the volcano.  High-viscosity magma does not allow for the exsolution of gas bubbles.

Thus, the gas bubbles will be trapped inside and increase pressure on the magma column to explode. The trapped gas thus provides the driving force for the explosion.

Thus, the correct answer is option C.

In pea plants, tall (T) is dominant to short (t). A plant with genotype Tt is crossed with a plant with type tt. What percentage of their offspring will be tall?

Answers

Answer:

50%

Explanation:

Draw a Punnet square to determine the percentage of offspring that are tall.

The green and blue highlighted columns and rows represents the genotype of the parents. To fill in the genotype of the offspring, write down the letter (T/t) of the parent allele from that row and column the offspring belongs to. By convention, the T is written before t. (The genotype of a tall offspring is written as Tt not tT)

Since the T allele is dominant, as long as the offspring has one T, the offspring is tall. The t allele is recessive, thus two ts (tt) is needed for the short trait to be expressed.

From the Punnet square, the result is 2 offsprings that are tall and 2 offsprings that are short.

Required percentage

[tex] = \frac{2}{4} \times 100\% \\ = \frac{1}{2} \times 100\% \\ = 50\%[/tex]

Explain the difference between AKI and CKD​

Answers

Answer:

Acute kidney injury (previously called acute kidney failure) is the sudden loss of kidney function, usually as a result of illness, drugs or injury. Acute kidney injury is commonly reversible. Chronic kidney disease (CKD) will progress to chronic kidney failure with time.

Explanation:

Answer:

AKI is reversible (for the most part) where CKD is not

Explanation:

AKI develops very suddenly. It is normally caused by an acute renal insult and encompasses a spectrum of renal impairment from minor changes in markers of renal function. Managing AKI includes; identifying and treating the underlying case and doing your best to minimize as many complications as possible.

CKD develops over time, normally taking a few months to years for it to show itself. It normally comes from having diabetes and hypertension. The disease itself is, more often than not, discovered when going through screening for other, unrelated, diseases. You can slow down the progress of renal failure but you can't treat it. CKD will eventually lead to permanent dialysis or the patient needing a kidney transplant.

6 How can you determine the origin of the oxygen released by photosynthesis?​

Answers

Answer:

because all green plants release oxygen and non- green plants do not release oxygen.

Explanation: One of the first uses of an isotopic tracer in biology was in the determination of the source of the oxygen produced by photosynthesis. Using a heavy isotope of oxygen, 18O, to label one of the two reactants in the photosynthetic process, Samuel Ruben and collegues at UC Berkeley were able to determine that the oxygen gas came not from carbon dioxide, but water.
