Explanation:
Shudras, on the other hand, obeyed the orders of their masters, because their knowledge of attaining moksha by embracing their prescribed duties encouraged them to remain loyal. Shudra women, too, worked as attendants and close companions of the queen and would go with her after marriage to other kingdoms.
Answer:
The definition of speciation is the formation of new species throught the course of evolution. There are many different ways it can occur.
- Geographic Isolation - Seperating two species, so that they are in different habitats. Over time these species get acquainted to heir habitats and start evolving to fit in it. Suppose there is a big lake where a species of fish lives, and the lake gets seperated. One side of the lake prefers dark fish and the other prefers lighter fish. On one side, dark fish becomes more prevalent and light fish becomes more prevalent on the ohter side. Soon, this species will split into two species, based on how different they are on the color of their scales.
- Temporal Isolation - This is when species mate a different times of the year. One example is if you have a bunch of frogs. Most of them mate in the summer. All of a sudden, some of them mate in the Spring as well. Soon these frogs mate a different times and become different species as they don't mate at the same time. The frogs that mate at differnt times can no longer, be the same species.
- Behavioral - This is when species have different mating calls or courthsips. Lets say you have birds that sing a specific tune to mate and then one day, another group fo birds in the same species sing a different tune. Soon, these two bird species will be different as they sing different tunes and can no longer mate with each other. If they can't mate with each other, they are no longer the same species.
The correct answer is twenty-fold.
Twenty fold refers to as having as equal to or holding as much as twenty times as many or much of a certain object. based on the given situation, between the years 1980 and 2007, the service exports worldwide increased twenty-fold, which means that service exports doubles as much as twenty times during the period of 1980 to 2007.

The gravitational model explains how particles of matter attracted to one another are positioned in space and how Bohr's model of electrons orbiting the nucleus fits this model.
<h3>What drawbacks exist with the Bohr model?</h3>
- Larger atoms were beyond the scope of the Bohr atomic model.
- The various line strengths in emission spectra were not consistent with the atomic model.
- The variations in emission spectra observed in the presence of a magnetic field were not covered by the Bohr model (known as the Zeeman effect).
<h3>What does the Bohr model represent?</h3>
Model of Bohr. The Rutherford-Bohr model, also known as the Bohr model, was developed by Niels Bohr in 1913 and is used to explain the structure of atoms in atomic physics. It shows that each atom consists of a small, positively charged nucleus that is surrounded by electrons that move in circular orbits around it.
