Sia ? 4 years, 7 months ago

Mitosis	Meiosis
Interphase
Each chromosome replicates. The result is two genetically identical sister chromatids (However, do note that interphase is technically not a part of mitosis because it takes place between one mitotic phase and the next)	Chromosomes not yet visible but DNA has been duplicated or replicated
Prophase
Prophase –Each of the duplicated chromosomes appears as two identical or equal sister chromatids, The mitotic spindle begins to form. Chromosomes condense and thicken	Prophase I – crossing-over recombination – Homologous chromosomes (each consists of two sister chromatids) appear together as pairs. Tetrad is the structure that is formed. Segments of chromosomes are exchanged between non-sister chromatids at crossover points known as chiasmata (crossing-over)
Metaphase
Metaphase -The chromosomes assemble at the equator at the metaphase plate	Metaphase I Chromosomes adjust on the metaphase plate. Chromosomes are still intact and arranged as pairs of homologues
Anaphase
Anaphase – The spindle fibres begin to contract. This starts to pull the sister chromatids apart. At the end of anaphase, a complete set of daughter chromosomes is found each pole	Anaphase I Sister chromatids stay intact. However, homologous chromosomes drift to the opposite or reverse poles
Mode of Reproduction
Asexual Reproduction	Sexual Reproduction
Occurrence
All the cells	Reproductive cells
Function
General growth and repair, Cell reproduction	Genetic diversity through sexual reproduction
Cytokinesis
Occurs in Telophase	Occurs in Telophase I and in Telophase II

Sia ? 4 years, 7 months ago

Both are different. Private sector income includes only factor income earned by private sector within domestic territory whereas private income includes private sector income, NFIA and all current transfers from within and outside the country. Thus, private income is a national and broader concept whereas income from domestic product accruing to private sector is a domestic concept.

Explain any two impacts of government policy changes on business and industry

Posted by Shilpa Sinha 4 years, 5 months ago

CBSE > Class 12 > Business Studies

1 answers

Sia ? 4 years, 5 months ago

The two impacts of government policy changes on business and industry are:

Increasing competition: As a result of changes in the rules of industrial licensing, entry of foreign firms creates competition for Indian firms, especially in service industries like telecommunication, airlines, banking, insurance, etc which were earlier placed in the public sector.
More demanding customers: Government policies leading to economic liberalisation allow consumers to become well-informed, increase their purchasing power (through rising incomes) and change their lifestyle, which makes them more demanding about quality and value-driven products/services.
