A-00001: Ordinal: भले ही फोन नंबर 'न्यूमेरिक्स' हों, लेकिन उनके जोड़ और घटाव का कोई मतलब नहीं है। Even though phone numbers are 'numerics', their addition and subtraction have no meaning.
A-00002: Snakes could lower their standard metabolic rates, some by up to 72%. Some snake species could survive for up to two years without a meal. Same is true with most of living beings: even humans can survive up to 60 days without food - when the intake of food is reduced, the metabolic activity of bodies is automatically reduced.
A-00003: Hiccups are caused by involuntary contractions of the muscle that separates chest from abdomen. This causes your vocal cords to close momentarily which produces the characteristic sound of a hiccup. The exact cause of excessive yawning isn’t known. However, it is mostly attributed to drowsiness, tiredness or fatigue.
A-00004: Answer to be prepared!
A-00005: यह बैठे और सोते समय किसी के पैर को (अनियंत्रित) तरीके से हिलाने की अवस्था को कहते हैं। It is (uncontrolled) shaking of one's leg(s) while sitting and sleeping.
A-00006: Please refer to this page!

A-00008: The current is passed through tungsten wires which gets heated to temperature up to 3000 [K]. This makes it emit the light.
A-00009: Answer to be prepared!
A-00010: There is no record and extent of impact of radition on humans and plants.
A-00011: जब पानी जम जाता है, तो यह फैलता है और इसका घनत्व कम हो जाता है। 4 [डिग्री सेल्सियस] पर पानी का घनत्व सबसे अधिक होता है। पानी से अधिक ऊँचा होने के कारण, बर्फ अधिकांश आकृतियों के लिए तैरने लगती है। When water frezes, it expands and its density reduces. Water has highest density at 4 [°C]. Being ligher than water, ice tends to fload for most of the shapes.
A-00015: The answer lies in the fact "why sky is blue?"
A-00016: उच्च तापमान पर भोजन तेजी से पकता है। पानी का उबलता तापमान 100 [C] से ऊपर नहीं बढ़ सकता है जब तक कि इसकी सतह के ऊपर का दबाव वायुमंडलीय दबाव से ऊपर नहीं बढ़ जाता है। प्रेशर कुकर पानी की सतह पर दबाव बढ़ाता है और इसलिए 120 - 150 [C] में पानी उबलता है। A food cooks faster at higher temperature. The boiling temperature of water cannot increase above 100 [°C] unless pressure above its surface increases above stmospheric pressure. Pressure cooker increases the pressure over water surface and hence water boils in the range 120 - 150 [°C]..
A-00017: Fish need oxygen to breathe like any other mammals. They rely on special organs called 'gills' which are feathery organs full of blood vessels. A fish breathes by taking water into its mouth and forcing it out through the gill passages. During this process, dissolved oxygen moves into the blood and travels to the fish's cells.

A-00023: Answer to be prepared!
A-00024: Typical piece of paper is composed mostly of cellulose (wood) fibers. These fibers are stiffened and held together by strong hydrogen bonds between the cellulose fibers. When paper gets wet, H-bonds between cellulose fibers tend to form hydrogen bonds with the hydrogen and oxygen groups in the cellulose fibers and in turn get broken down and the fibers separate more easily. Rather than cellulose fibers, paper money is composed of cotton or linen fibers that do not create molecular bonds with water molecules to the same extent as notebook paper.
A-00025: There is a continuous regeneration of layers of tissues in the inner walls of the stomach which keeps them intact.
A-00026: Answer to be prepared!

A-00029: Answer to be prepared!
A-00030: Answer to be prepared!
A-00031: Both of the bird's feet are on the same wire and there is no noticeable difference in electric potential between them. The electricity prefer to continue travelling along the wire rather than passing through the body of the bird. If a bird touched two wires at the same time then electricity would flow through it and they will get electrocuted. पक्षी के दोनों पैर एक ही तार पर हैं और उनके बीच बिजली की क्षमता (वोल्टेज) में कोई अंतर नहीं है। बिजली पक्षी के शरीर से गुजरने के बजाय तार में प्रवाह जारी रखना पसंद करती है। यदि एक पक्षी एक ही समय में दो तारों को छूता है, तो उसके माध्यम से बिजली प्रवाहित होगी और वे विद्युत-आघात से मारे जाएंगे।
A-00032: डॉल्फ़िन और व्हेल सही अर्थों में मछली नहीं हैं! उनमें मनुष्यों की तरह स्तनधारियों की कई विशेषताएं हैं। Dolphins and whales aren't fish in true sense! They have many features common to mammals, just like humans.
