Q2. In the north-west, India shares its land boundaries with which country?
उत्तर-पश्चिम में भारत भूमि की सीमाएं किस देश के साथ लगी हुई हैं?
Kumaun Himalayas, west-central section of the Himalayas in northern India, extending 200 miles (320 km) from the Sutlej River east to the Kali River. The range, comprising part of the Siwalik Range in the south and part of the Great Himalayas in the north, lies largely within the state of Uttarakhand, northwest of Nepal. It rises to 25,646 feet (7,817 metres) at Nanda Devi, the range’s highest peak, and to 25,446 feet (7,756 metres) at Kamet, near the Chinese border. At elevations above 14,000 feet (4,300 metres), snow covers the mountains throughout the year. Glaciers and snowmelt feed the headstreams of the Ganges River in torrents that rush through gorges and steep-sided ravines.
Q4. Potato, tomato and brinjal are three different species but all belong to which genus?
आलू, टमाटर और बैंगन तीन विभिन्न वर्ग (स्पीशीज) है परन्तु वे किस वंश (जीनस) के अंतर्गत आते हैं?
Solanum – Solanum is a large and diverse genus of flowering plants, which include two food crops of high economic importance, the potato and the tomato.
Panthera – The informal term “big cat” is typically used to refer to any of the four largest (living) members of the entire Panthera genus. Among the five total species within the Panthera genus, these four are the only cats that are able to roar. In descending order of their maximum potential size, these four species are: tigers, lions, jaguars, and leopards, with the tiger (Panthera tigris) being the largest. A more liberal and expansive definition is sometimes used which may include the snow leopard, puma, clouded leopard, Sunda clouded leopard and/or cheetah, although these added species do not roar
Felis – Felis is a genus of small and medium-sized cat species native to most of Africa and south of 60° latitude in Europe and Asia to Indochina. The genus includes the domestic cat. The smallest Felis species is the black-footed cat with a head and body length from 38 to 42 cm (15 to 17 in).
Tigris – The tiger (Panthera tigris) is the largest cat species, most recognizable for their pattern of dark vertical stripes on reddish-orange fur with a lighter underside. The species is classified in the genus Panthera with the lion, leopard, jaguar, and snow leopard.
Q5. The first formed primary xylem elements are called ___________.
सबसे पहले बनने वाले प्राथमिक जाइलम तत्व को _______ कहते हैं|
Protoxylem is the first part of the primary xylem that matures and these cells are usually smaller than the metaxylem. Metaxylem is the part of the primary xylem that differentiates after the protoxylem and these cells are usually larger than the protoxylem.
Xylem fibres – The fibres associated with xylem are known as xylem fibres. Xylem fibres are very much elongated with tapering ends. The fibres are dead cells having lignified walls with narrow lumen.They provide additional mechanical support to the plant body.
Xylem parenchyma – Living parenchyma cells associated with the xylem are known as xylem parenchyma. It is the only living component found in xylem tissue. Xylem parenchyma cell wall is thin and made up of cellulose. They act as storage house of starch and fat with assisting in conduction of water.
Q6. Nereis, Pheretima (Earthworm) and Hirudinaria (blood sucking leech) are examples of which Phylum?
नेरिस फेरेटिमा (केंचुआ) तथा हीरुडीनेरिया (रक्तचूषक जोंक) किस संघ के उद्धरण हैं?
Coelenterata – All coelenterates are aquatic, mostly marine. The bodyform is radially symmetrical. The body has a single opening, the hypostome, surrounded by sensory tentacles equipped with either nematocysts or colloblasts to capture mostly planktonic prey. Some examples are corals, which are typically colonial, and hydra, jelly fish and sea anemones which are solitary.
Aschelminthes – Aschelminthes includes one very large group (Nematoda) and smaller groups. (Rotifera, Gastrotricha,Kinorhyncha, and Nematomorpha). Mostly aquatic, free-living or parasitic.Usually small, even microscopic, Some are a meter or more in length.Body cylinder, vermiform, unsegmented, and triploblastic.
Annelida – The annelids, also known as the ringed worms or segmented worms, are a large phylum, with over 17,000 extant species including ringworms, earthworms, and leeches.The species exist in and have adapted to various ecologies – some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments.The annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms.
Arthropoda – An arthropod is an invertebrate animal having an exoskeleton(external skeleton), a segmented body, and paired jointed appendages. Arthropods are characterized by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. The rigid cuticle inhibits growth, so arthropods replace it periodically by moulting.
Q7. In humans, the sound is produced by the ________.
Oesophagus – The oesophagus is also known as the gullet or food pipe. It’s part of the digestive system, which is sometimes called the gastro-intestinal tract (GI tract). The oesophagus is a long, muscular tube that connects your mouth to your stomach.
Larynx – A tube-shaped organ in the neck that contains the vocal cords. The larynx is about 5 cm (2 in.) long. It is part of the respiratory system and is located between the pharynx and the trachea.
Medulla – The medulla oblongata helps regulate breathing, heart and blood vessel function, digestion, sneezing, and swallowing. This part of the brain is a center for respiration and circulation. Sensory and motor neurons (nerve cells) from the forebrain and midbrain travel through the medulla.
Epiglottis – The epiglottis is a flap made of elastic cartilage covered with a mucous membrane, attached to the entrance of the larynx. It projects obliquely upwards behind the tongue and the hyoid bone, pointing dorsally. It stands open during breathing, allowing air into the larynx.
Q8. The vocal cords in men are about _______ long.
The male vocal folds are between 17 mm and 25 mm in length. The female vocal folds are between 12.5 mm and 17.5 mm long. Folds are pearly white – females have whiter cords than males. The difference in vocalfold size between men and women means that their voices have a different pitch.
Q9. The _______ uses an addressing scheme known as URL to indicate the location of files on the web.
______ द्वारा एड्रेसिंग योजना को प्रयोग किया जाता है जिसे यूआरएल के नाम से जाना जाता है जो यह बताता है कि वेब पर फाइल कहां है|
World Wide Web – The World Wide Web (WWW) is a network of online content that is formatted in HTML and accessed via HTTP. The term refers to all the interlinked HTML pages that can be accessed over the Internet. The World Wide Web was originally designed in 1991 by Tim Berners-Lee.
.SQL – SQL stands for Structured Query Language.SQL is a domain-specific language used in programming and designed for managing data held in a relational database management system, or for stream processing in a relational data stream management system.
String – Strings, which are widely used in Java programming, are a sequence of characters. In the Java programming language, strings are objects. The Java platform provides the String class to create and manipulate strings.
Q10. Most liquids that conduct electricity are solutions of acids, bases and ______.
विद्युत चालन करने वाले अधिकांश द्रव अम्लों, क्षारकों और ______ के विलियन होते हैं|
