Essay on dipawali in 500 words​

Answer»

Answer:

Explanation:

National festivals are the lifeblood of a nation. They add charm and thrill to our humdrum life. India being a melting -pot of religions, race, and cultures, it has a plethora of festivals and feasts.

 AMONG these, Diwali perhaps is the most pan-Indian festival celebrated with great pomp and mirth throughout the length and breadth of the country. Diwali, better known as, Deepawali among the Indian masses, is a festival of lights.

The exact origin of the festival is not known. Some BELIEVE that it is connected with the triumph of Lord Krishna over Nakrasura. Some associate the origin of the festival to the worship of goddess Lakshmi, the goddess of wealth.

However, the most prevalent belief is that the festival marks the victory of Lord Rama over Ravana. On this day, it is believed that Rama came back to Ayodhya after his victory over evil Ravana of Lanka who had taken away his wife, Sita.

People greatly rejoiced the return of their beloved prince. They lighted up whole Ayodhya with earthen lamps, decorated their HOUSES and welcomed them with pomp and ceremony. The present day celebration of Diwali is held in remembrance of this event.

Diwali is generally celebrated in late October or early November, soon after the rainy season is over. A lot of preparation goes in before the actual festival. Houses are cleansed, white washed and painted. Every nook and corner of the house is swept clean.Thereafter, in the evening earthen lamps and decorative lights are put in and around the house giving an atmosphere of joy and happiness. As the night approaches, children light up the sky with their firecrackers. The streets and bazaars bear a dazzling look.

Illumination of every hue and colour light up shops and buildings. Thus, there is gaiety, cheerfulness, merrymaking and fun everywhere. There is joy on every face. On this day every one put on their best dress which has been purchased well in advance. People exchange greetings and share sweets and meals as a mark of friendship and brotherhood.

Diwali is an important day for the traders. It is the beginning of Hindu commercial calendar. Many of them start their new account books on this day, after the puja held in honour of goddess Lakshmi, the goddess of wealth. Special prayers are offered to goddess Lakshmi for her blessings on the household and on business.

The festival of Diwali teaches us many values of life. More than anything else the festival symbolises the ultimate victory of good over evil. It teaches us that one day or other the evil existing in this world would be subdued by goodness and righteousness. Rama’s obedience to parents, Sita’s faithfulness, Lakshman’s unflinching love for his brother, etc., teach us many noble LESSONS of life.  

The festival is a national festival celebrated by everyone irrespective of caste, creed and race. It therefore, promotes unity, COMMON brotherhood, and communal harmony. Hence, in a world like ours, broken by narrow domestic walls of religious fanaticism and social disharmony, a festival like Diwali can bring people together, heal wounds, and can help in fostering national integration.Of late, external celebrations of Diwali have taken predominance over its religious content. As years proceed the celebration is becoming more commercial and superficial leading to much unhealthy practices, like gambling and drinking. Therefore, there is an urgent need to put sobriety, restraint, and caution in the present-day celebration of Diwali, so as to maintain its sanctity and original grandeur.

Cell association in protozoa vs cellular differentiation

Answer»

Answer:

Protozoa (also protozoan, plural protozoans) is an informal term for single-celled eukaryotes, either free-living or parasitic, which feed on organic matter such as other microorganisms or organic tissues and debris.Historically, the protozoa were REGARDED as "one-celled animals", because they often possess animal-like behaviors, such as motility and predation, and lack a cell wall, as found in plants and many algae. Although the traditional practice of grouping protozoa with animals is no longer considered valid, the term continues to be used in a loose way to identify single-celled organisms that can move independently and feed by heterotrophy.

In some systems of biological classification, Protozoa is a high-level taxonomic GROUP. When first introduced in 1818, Protozoa was erected as a taxonomic class,but in later classification schemes it was elevated to a variety of higher ranks, including phylum, subkingdom and kingdom. In a series of classifications proposed by Thomas Cavalier-Smith and his collaborators since 1981, Protozoa has been ranked as a kingdom. The seven-kingdom scheme presented by Ruggiero et al. in 2015, places eight PHYLA under Kingdom Protozoa: Euglenozoa, Amoebozoa, Metamonada, Choanozoa sensu Cavalier-Smith, Loukozoa, Percolozoa, Microsporidia and Sulcozoa.[9] Notably, this kingdom excludes several major groups of organisms traditionally PLACED among the protozoa, including the ciliates, dinoflagellates, foraminifera, and the parasitic apicomplexans, all of which are classified under Kingdom Chromista. Kingdom Protozoa, as defined in this scheme, does not form a natural group or clade, but a paraphyletic group or evolutionary grade, within which the members of Fungi, Animalia and Chromista are thought to have evolved.

Cellular differentiation is the process where a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. ... Differentiation continues in adulthood as adult stem cells divide and create fully differentiated daughter cells during tissue repair and during normal cell turnover.

Body parts of molluscs where they accumulate heavy metals

Answer»

Answer:

Explanation:

For monitoring heavy metal pollution of streams in urban and industrial AREAS residue analyses were undertaken in different aquatic invertebrates with SPECIAL regard to the freshwater molluscs Bithynia tentaculata, Physa acuta, Radix peregra and Dreissena polymorpha to define the heavy metal residues in shell and soft body parts in natural populations.

To control the distribution and dynamics of the heavy metals, the accumulation and elimination behaviour is determined after experimental contamination tests with cadmium, lead and zinc and their complexes for synergisms on standardized populations under laboratory conditions.

Due to a strong accumulation of these organisms they appear to be well suited for monitoring programs. Experimental studies SHOW, that zinc and lead absorbed with the food accumulate in the haemolymph, the food muscle and the protein gland. The different rates of accumulation depend however among others on the different PHYSIOLOGICAL variables as well as on population specific strategies. Furthermore, different mechanisms result in a rivalry among the heavy metals for uptake.

Explain the events upto double fertilisation after the pollen tube enters one of synergids in an ovule of an angiosperm?

Answer»

Answer:

when pillen tube enter one of the synergids, the pollen tube release the two male gametes into the the cytoplasm of the synergids. one of the male gametes move so towards the egg and fuses with nucleus thus syngamy take place. this result in the FORMATION of DIPLOID cell, the zygote the other male gamete moves towards the polar nucei located in the Central cell and fuses with them to PRODUCE a triploid primary Endosperm nucleus . as this involve the FUSION of 3 haploid nuclei it termed as triple fusion since two TYPE of fusion. synfamy and triple fusion take place in an embryo sac the phenomenon is termed as double fertilisation
