Correct Answer: Scientific decisions

Solution : Decisions based on management principles tend to be more realistic and free from personal bias. Principles of management has been developed after repeated experimentation.

Hence, Option D is correct.

Hello student,

An evolution never takes place from a single organism, but takes place due to populations because there are plenty of chances of genetic recombinations. Evolution is defined as change in the heritable characteristics of a biological population which is carried from generation to generation and evolution also creates variation.

Hope you found it helpful!!

Hello,

Democracy has been defined government, of the people, by the people and for the people.

India after independence scraped the Zamindari system and mixed petty Indian states into part B states promising acquainted purses to rulers and later on these privy pusses were also scraped, as these were considered uneconomic and hindrance for development.

Thank you.

Hello student ,

Marketing concept can be defined as “a strategy that companies can use to satisfy the needs of their customers, increase profits, and beat the competition”.Marketing concept is the way of life in which all the resources of an organisation are mobilized to create, stimulate and satisfy the consumer at a profit. It represents a distinct philosophy of business and considers marketing more than a physical process.

You can divide marketing concepts into five different parts. These are:

1. Production concept
2. Product concept
3. Selling concept
4. Marketing concept
5. Societal concept

The evolution of these started from a very simple idea of what customer wants and how they satisfy needs by means of product.It constantly stresses on the needs of the buyers. It focuses on the customer.Companies start by making products more efficiently from the competitors to make a place stronger in market.

Evolution does not always lead to more advanced species. Evolution is simply a description of the way change occurs in biological creatures over many generations in order to better exploit a certain environment. Evolution sometimes leads to progress, but it sometimes leads in the opposite direction. For instance, the Texas blind salamander has lost his eyes after many generations of evolution due to the uselessness of eyes in the dark caves where he dwells. As reported by biologist David M. Hillis, these salamanders have successfully adapted to their environment by loosing their eyes. But going blind does not seem to be much in the way of progress from a global perspective.

Natural evolution did not create a chicken that lays so many unfertilized eggs. Human engineering created such chickens. You could call the process "human-caused evolution", "artificial selection", or "selective breeding". The evolutionary principles of survival of the fittest and inheritance of genetic traits still apply in artificial selection, but the agent that determines who is the fittest is a human and not a natural environmental pressure. In selective breeding, humans choose only the individuals of a species that have desirable traits to use as parents for the next generation. After several generations of selective breeding, the organism gains more and more of the desired trait. It's not that the humans are training or teaching the organism to have the desired trait. Rather, genetic mutations cause the next generation of individuals to have a variety of new traits (the "new traits" are typically very small modifications when looking at just a single generation). Most of the mutation-caused traits are undesirable or irrelevant. But the few organisms with desirable traits are selected and used to create the next generation.

Ostriches never hide their head in the sand, especially not when approached by an enemy. In fact, ostriches can become quite aggressive when threatened. According to the book "Flightless Birds" by Clive Roots, ostriches respond to predators by either running away or attacking. Ostriches have very powerful legs and have been known to kill people with a slashing kick. When fleeing danger, ostriches can reach 50 mph and can sustain a speed of 30 mph for a half hour. This myth perhaps comes from the fact that ostriches have long necks and small heads so that when they are bending over to swallow sand, it looks like their head is buried. But harboring the notion that ostriches are dumb and harmless can be a deadly mistake for humans to make.

Dear aspirant

This two chapters are most important topics from class 12th also one of most important topics which examiner likes to ask. Minium of 12-13 questions will come from these two topics which can provide you 40-50 marks. So you shouldn't leave this portion and try to be strong enough in this topic.
