The Portrait of a Lady is a very appropriate title for the story as in the complete story, the author keeps on talking about his grandmother. Whether the start, where she is dressing the author and singing prayers or at the near end when the lady started feeding the birds in the balcony; every branch of the plot in the story highlights the attribute of the old lady. Moreover, we can notice that not once did the writer trace anything other than the life of his grandmother. So, more easily, we can state that the whole story is like some drawing of the writer's grandmother. However, it not only gives physical traits like an image, instead covers up the several emotions and feelings of the lady too. Hence, it is a wise title that is very clearly stating the subject (the main character) of the plot because of which the audiences can easily infer about what they are going to study in the story.

Commerce is concerned with buying, selling and distribution of commodities. It is an organised system for the exchange of goods and services. It involves not only the functions of buying and selling but several other activities required to facilitate buying and selling.
The purpose of commerce is to provide the right goods to the right persons at file right time and at the right place. Therefore, we can say business depends on commerce.

The basic economic activities of life are production, distribution and disposition of goods and services. A society will be facing scarcity of resources during the time of fulfillment of these activities.
 

The central problems of an economy revolve around these factors.

1. What to produce?
   It is one of the central problems that arise in an economy. It is related to the type of goods and services that need to be produced and the quantity to be produced.
2. How to produce?

   This aspect deals with the process or technique by which the goods and services can be produced. Generally, there are two techniques that can be used for producing, which are:

   *Labour Intensive Techniques
   *Capital Intensive Techniques
3. For whom to produce?
   This problem deals with determining the people who will be the final consumers of the goods produced. As the resources are scarce in an economy, it becomes difficult to cater to all sections of society.

Charles Darwin described the idea of evolution in 1859 in his book, The Origin of Species

The dead remains of plants and animals that remain buried inside the layers of earth for millions of years and then preserved for the purpose of study are known as fossils. The study of fossils is significant as it helps us to know about the evolutionary relationships between different organisms and thus also tells us how far this relationship goes.

Avogadro’s law, also known as Avogadro’s principle or Avogadro’s hypothesis, is a gas law which states that the total number of atoms/molecules of a gas (i.e. the amount of gaseous substance) is directly proportional to the volume occupied by the gas at constant temperature and pressure. Avogadro’s law is closely related to the ideal gas equation since it links temperature, pressure, volume, and amount of substance for a given gas.
