Answer:

Last Option

Explanation:

I'm not sure about this one so I had to google the equation real quick.

The equation for the derivative of an inverse is:

$[f^{-1}(x)]'=\frac{1}{f'(f^{-1}(x))}$

From my understanding of the format, it might look like a hard equation to understand but its pretty simple.

The inverse derivative is 1 divided by the derivative of f(x), except you plug in f⁻¹(x) into that derivative.

How did some students and tutors find shortcuts to learning? How did the Chinese government react to these shortcuts?

Nuetrik [128]

According to a different source, this question refers to the text "The Chinese Civil Service Exam System” by Ichisada Miyazaki.

In this text, we learn that the Chinese civil service examination system originated in Ancient China nearly fourteen hundred years ago. Therefore, it is one of the oldest examination systems in the world.

The system was intended to identify the most capable young men in China, and educate them so that they might become part of the government. However, this was a long, difficult and tedious process, and many students and tutors found useful shortcuts to learning. For example, rapid-study methods were devised, such as compiled collections of examination answers.

The Chinese government was aware of such methods, which were strongly condemned. Students who employed them were failed. The government also issued frequent prohibitions of the publication of such materials. However, the success of the business meant that such prohibitions were often unsuccessful.

What are the properties of the founder effect?

Anit [1.1K]

The influence of the founder in population genetics is the loss of genetic advantages that occur when a new generation of the population arises from a very small number of individuals who were previously part of a larger group (for example, a small group of animals survived a mass extinction event). Ernest Meyer was the first to develop the full concept of the term in 1952, and was able to do so using other theoretical work by scientists such as Sioual Wright. As a result of the loss of genetic differentiation, the new generation may be very different from their grandparents both genetically and morphologically. The influence of the founder is believed to lead in some exceptional cases to evolutionary diversity and to the emergence of new types of more sophisticated creatures.

In the picture to the left, indigenous people have almost equal numbers of red and blue individuals, while the three smaller founding groups show that one color can become predominant or fixed (the influence of the founder) as a result of random selection from the indigenous population. A bottleneck may also cause a founding effect even if it does not represent a completely new population.

The influence of the founder is a special case of genetic drift as well as the exposure of the new population to the influence of the founder. They are also often very small populations, and because of this, they appear to be increasingly sensitive to genetic drift, increase in internal reproduction and relatively low genetic differentiation. This can be seen in the limited gene ponds of Iceland, the Isle of the Resurrection and the Pitcairn Islands. Another example of this phenomenon is the enormous proportion of the Deaf population in Martha Vineyard, which led to the development of Marathas Vineyard's sign language.
