Evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms' observable traits. Genetic changes include mutations, which are caused by damage or replication errors in organisms' DNA. As the genetic variation of a population drifts randomly over generations, natural selection gradually leads traits to become more or less common based on the relative reproductive success of organisms with those traits.

The age of the Earth is about 4.5 billion years. The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago. Evolution does not attempt to explain the origin of life (covered instead by abiogenesis), but it does explain how early lifeforms evolved into the complex ecosystem that we see today. Based on the similarities between all present-day organisms, all life on Earth is assumed to have originated through common descent from a last universal ancestor from which all known species have diverged through the process of evolution.

All individuals have hereditary material in the form of genes received from their parents, which they pass on to any offspring. Among offspring there are variations of genes due to the introduction of new genes via random changes called mutations or via reshuffling of existing genes during sexual reproduction. The offspring differs from the parent in minor random ways. If those differences are helpful, the offspring is more likely to survive and reproduce. This means that more offspring in the next generation will have that helpful difference and individuals will not have equal chances of reproductive success. In this way, traits that result in organisms being better adapted to their living conditions become more common in descendant populations. These differences accumulate resulting in changes within the population. This process is responsible for the many diverse life forms in the world.

The work done by house wife is disvaluated because people thought that house wife do not do any work.This was not true.House wife do a lot of work.The main responsibility for house work and care-giving is tasks lies with women.Yet the work that they do is not recognized as work.It is assumed that there is something that come naturally to women.Thus there are not being paid for.

Yogita Ingle 4 years, 11 months ago

The job of a housewife never ends. Housewife’s responsibility starts every day by taking care of the house, children and her husband. Her role is to ‘keep the house clean’, take care of the sick.

It is a job which has no end and the whole house depends on the housewife. People when they work outside get remuneration for it so it is evaluated in terms of money.  

If the housewife is a working lady her jobs still remain the same at home. She needs to multi-task and take care of the household. Normally the value of work is determined with amount of money one is paid for it. But in a household the women do not get ‘paid for the work’ hence it is not seen as a value.

Women with disabilities face significantly more difficulties – in both public and private spheres – in attaining access to adequate housing, health, education, vocational training and employment, and are more likely to be institutionalized.   They also experience inequality in  hiring, promotion rates and pay for equal work, access to training and retraining, credit and other productive resources, and rarely participate in economic decisionmaking.

Promoting gender equality and empowerment of women is essential to the achievement of the internationally agreed development goals, including the Millennium Development Goals. Women and girls with disabilities experience double discrimination, which places them at higher risk of gender-based violence, sexual abuse, neglect, maltreatment and exploitation.

Temperature is measure by a instrument called thermometer. Temperature of human boye is measured by clinical thermometer.The used to measure it is °C or °F.

Yogita Ingle 4 years, 11 months ago

Reading of thermometer and measuring of temperature:

  • Take a clinical thermometer and hold it horizontally with reading scale towards your eye.
  • Do not hold the thermometer from the bulb.
  • Rotate the thermometer slightly clockwise and anticlockwise. By doing this you will see a shiny thin silvery thread.
  • The end of the silvery thread shows the reading of temperature. If mercury lining ends at 37, the reading is 37°C.
  • Wash the bulb end of thermometer with an antiseptic solution.
  • Give two or three jerks slightly. By doing this the mercury level would fall. When it falls to 35°C or below, put it below the tongue and wait for one minute.
  • Take out the thermometer and read the temperature. Temperature would be near 37°C.
  • The normal body temperature is 37°C. This can differ from person to person.

The jangir is the revenue assignment for the mansabdar.Mansabdar had right to collect revenue from jangir but not reside there or administer the jangir.

Yogita Ingle 4 years, 11 months ago

Mansabdars were the patrons who joined the Mughal service. The term mansabdar refers to an individual who holds a mansab, which means a position or rank. It was a grading system used by the Mughals to fix the rank, salary and military responsibilities. Each mansabdar had to maintain a specified number of sawar or cavalrymenA jagir was a revenue assignment for the mansabdars. The mansabdars had the right to collect revenue from a jagir but they could not reside in or administer the jagir. They only had rights to the revenue of their assignments which was collected for them by their servants while the mansabdars served in some other part of the country.
In Akbar’s reign, these jagirs were carefully assessed so that their revenues were roughly equal to the salary of the mansabdar.
By Aurangzeb’s reign, the actual revenue collected was often less than the granted sum. Moreover, a huge increase in the number of mansabdars meant a long wait before they received a jagir. These and other factors created a shortage in the number of jagirs. As a result, many jagirdars tried to extract as much revenue as possible while they had a jagir.
These factors during Aurangzeb’s reign led to the peasantry’s suffering and loss.
