yir-ytnf-wdbEvery month a man consumes 25 kg rice and 9 kg wheat. The price of rice is 20% of the price of wheat and thus​

Answers

The price of rice and consumption of wheat %decrease in the amount of rice is 36%.

What makes consumption so important?

One of the more complex concepts in economics, consumption is crucial since it influences the health and development of the economy. Businesses can start up and offer a variety of fantastic things, but if we don't buy or use them, they won't last very long.

Calculation:

Suppose wheat costs x per kilogram. Wheat will then cost 5 times as much per kilogram.

Expenditure on rice = 25*x = 25x.

Expenditure of wheat = 9*5x = 45x.

Total cost,

25x + 45x = 350.

70x = 350.

x = 5.

Hence, price of Rice = Rs. 5 per kg.

Price of wheat = 25 per kg.

price of wheat = 25 ---- 20% ----> Rs. 30 per kg.

Rice be N kg

N*5 + 9*30 = 350.

N = 16 kg.

Rice decrease as a percentage = [(25-16)*100]/25=36%.

The complete question is -

Every month a man consumes 25 kg rice and 9 kg wheat. The price of rice is 20% of the price of wheat and thus he spends total Rs. 350 on the rice and wheat per month.

An autopsy report shows evidence of a gunshot wound and mentions
exsanguination (extreme blood loss) and homicide. The mechanism of
death in this case would be
gunshot wound
homicide
exsanguination
No answer text provided.

The mechanism of death is the physiological derangement that results in death. An example of a mechanism of death due to the gunshot wound described above is exsanguination extreme blood loss.

Homicide is defined as the act of one person that directly causes the death of another. Homicide also includes death occurring during or in connection with the commission of a crime. A death mechanism describes a particular change in the body that brought about the end of life. For example, if the cause of death is a shootout.

The mechanism of death could be exsanguination, exsanguination, or cessation of brain function. A death certificate must be ordered within 72 hours, but the coroner's investigation into the cause of death can take weeks or months. That is, the cause of death is listed as pending on the certificate. This is the default if the cause of death is still unknown.

Answers

Energy and energy transition are depicted graphically and mathematically using energy flow diagrams, also known as energy flow charts.

Energy production used as unprocessed fuels to feed a system, supply of energy, transformation or conversion, losses, and energy in use can all fall under energy flow. The autotrophs that absorb energy from the sun are an excellent example of how energy moves through an ecosystem. The autotrophs are then consumed by herbivores, who convert the plant's energy into energy flow they can use. After that, carnivores eat the herbivores, and then other carnivores eat the carnivores is energy flow.

the arrows in the diagram stands for forces in earth,s crust pulling apart the two slabs of rock. this force is called

a.) tension
b.) elavation
c.) compression
d.) shearing


Answers

Answer:

I'm pretty sure it is c or a

Forces in earths crust pulling apart the two slabs of rock, this force is called Tension. Therefore, option (A) is correct.

Earth's crust tension pulls rock apart. At divergent plate borders, tectonic plates move apart. Faults form when tensional forces strain and thin rocks when plates separate. These faults can create rift valleys, mid-ocean ridges, and other geologic features.

Seafloor spreading and continental rifting are driven by tension. As plates separate, magma from the mantle rises to build new crust. New crust is formed at mid-ocean ridges. Tensional forces can also cause continental rifting and ocean development. Tension forms Earth's crust and moves tectonic plates. Therefore, option (A) is correct

An equilibrium price of a product is the price that equates the demand for the product with its supply.

In other words, the equilibrium price is the price at which demand equals supply.

On a graph of price against quantity, the demand curve slopes downward from left to right. On the other hand, the supply curve slopes upward from left to right on the same graph.

The price at which the demand curve intersects the supply curve on the graph is known as the equilibrium price.

reaction of pepsin.

Answers

Please find attached a sketch of the rate of reaction enhanced by pepsin at various pH, which shows a peak in the reaction rate at a pH of 2, and a reduction to (almost) zero rate of reaction at a pH of 6.

How can the variation of the rate of reaction with pH be graphically presented?

(a) The given parameters for the enzyme, pepsin are;

Type of enzyme = Proteindigesting enzyme

Location of enzyme = The stomach

Enzyme optimum pH = 2

pH at which the enzyme is denatured = 6

Required;

A sketch of a curve that shows the effect of varying pH values on the reaction rate of pepsin.

Solution;

An enzyme is denatured when it is not able to function to affect the rate of a reaction due to the loss of its tertiary or three dimensional structure.

The rate of the reaction when pepsin is denatured at a pH of 6 can therefore be taken as zero.

The graph of the variation of the rate of reaction for pepsin with pH consists of a curve that has a peak reaction rate at a pH of 2, and slopes downwards towards a reaction rate of zero at a pH of 6.

You need to find out why the GBR water is inhibiting (stopping) photosynthesis in the algae. The three major parts of photosynthesis are PSI, PSII and the Calvin cycle. The database has provided 3 things that could be inhibiting photosynthesis: high sea temperatures, paraquat, and diuron.

Answers

Explanation:

If the temperature increases then that will decrease the sugar but not the ATP and NADPH. So I predict that diuron will inhibit the photosynthesis because if photosystem II is infered with it then photosynthesis wouldn't work.And also, because paraquat will lower the NADPH and sugar but not ATP. Hence Diuron is the only choice left.

scientific hypothesis

By Kara Rogers • Edit History

scientific hypothesis, an idea that proposes a tentative explanation about a phenomenon or a narrow set of phenomena observed in the natural world. The two primary features of a scientific hypothesis are falsifiability and testability, which are reflected in an “If…then” statement summarizing the idea and in the ability to be supported or refuted through observation and experimentation. The notion of the scientific hypothesis as both falsifiable and testable was advanced in the mid-20th century by Austrian-born British philosopher Karl Popper.
