20Read the following and answer any 4 questions from 20 (i) to 20 (v). Infectious diseases are categorised based on their spread. Endemics, are a constant presence in a specific location. An outbreak is a greater-than-anticipated increase in the number of endemic cases. It can also be a single case in a new area. If it’s not quickly controlled, an outbreak can become an epidemic. An epidemic is actively spreading; new cases of the disease substantially exceed what is expected. An epidemic is often localized to a region, but the number of those infected in that region is significantly higher than normal. A pandemic is an epidemic that’s spread over multiple countries or continents.1x 4 20 (i) Based on the above information which of the following infectious disease is considered as endemic (i) COVID-19, (ii) African Sleeping Sickness, (iii) Malaria, (iv) Cholera (A)- (i), (ii), (iii) and (iv) (B) - (i), (ii), (iii) only (C) - (ii), (iii) only (D)- (i), (iii), (iv) only20 (ii) We should not allow mosquitoes to breed in our surroundings because they (A) multiply very fast and cause pollution (B) are vectors for many diseases (C) bite and cause skin diseases (D) are not important insects20 (iii) Find the correct combination of infectious diseases from the below(A)Flu, Cancer (B) Tuberculosis, Elephantiasis (C) Small pox, chicken poxD) Diabetes, Viral fever 20 (iv) Which one of the following is not correct statement regarding infectious diseases?(A) found after birth (B) caused by germs.

|
Answer» Answer: Explanation: a) Here X is lime water i.e. Ca(OH)2 , which is used to test the PRESENCE of carbon dioxide . The equation of the reaction of x with carbon dioxide: Ca(OH)2 + CO2 ----------> CaCO3 + H2O ---- when calcium hydroxide (lime water) react with carbon dioxide it forms a white precipitate of calcium carbonate (the solution turns milky ) with the release of water . b) Calcium oxide REACTS with water to PRODUCE slaked lime (calcium hydroxide) releasing a large amount of heat and also produces hissing sound . CaO(s) + H2O(l)---------> Ca(OH)2(aq)

The power of a lens is +4D. What is the nature of lens and what is its focal length?Where an object should be placed in front of a concave mirror to get a real image of thesize of obiect? |
|
Answer» <P>Answer:the power of a convex lens is always positive. as you can see here the power is +4D, therefore the nature of the lens is that it is a convex lens. we know, P = 1/f also the power of a lens is denoted in the TERMS of the unit dioptre (D). now putting the values in the equation 4D = 1/f therefore, f = 1/4 = 0.25 m in a concave mirror, youll get a real image as long as the OBJECT is between infinity and focus. size of the image depends upon the RELATIVE position of the object. pardon me for errors, if any Explanation: |

*वनस्पती सूर्यप्रकाशात क्लोरोफिलच्या मदतीने कार्बन डायऑक्साइड व पाणी यांच्यापासून ग्लूकोज तयार करतात. या प्रक्रियेतील जटिल संयुग ओळखा.*1️⃣ पाणी2️⃣ क्लोरोफिल3️⃣ कार्बन डायऑक्साइड4️⃣ ग्लूकोज |
|
Answer» ANSWER: 2) cholorofil प्रकाश-संश्लेषण में ग्लूकोज (C6H12O6) नामक कार्बोहाइड्रेट का निर्माण होता है। इसमें कार्बन (C) तथा ऑक्सीजन (C) तत्व के परमाणु कार्बनडाइऑक्साइड (CO2) से ही प्राप्त होते हैं। क्लोरोफिल क्लोरोफिल एक प्रोटीनयुक्त जटिल रासायनिक यौगिक है। यह प्रकाश-संश्लेषण का मुख्य वर्णक है। Explanation: सरल शब्द समीकरण जिसका उपयोग प्रकाश संश्लेषण की प्रक्रिया का वर्णन करने के लिए किया जा सकता है कार्बन डाइऑक्साइड + पानी -> ग्लूकोज + ऑक्सीजन + पानी है। प्रक्रिया के लिए एक संतुलित रासायनिक समीकरण 6CO2 + 6H2O -> C6H12O6 + 6O2 के रूप में लिखा जा सकता है। प्रकाश संश्लेषण प्रक्रिया द्वारा निर्मित अंतिम उत्पाद स्टार्च है। स्टार्च ग्लूकोज का एक प्रकार है। प्रकाश संश्लेषण में कार्बनडाइऑक्साइड और जल के बीच रासायनिक क्रिया के साथ गुलुकोज का निर्माण होता है तथा ऑक्सीजन मुक्त होती है। जहां कार्बन डाइऑक्साइड और पानी ग्लूकोज और ऑक्सीजन के उत्पादन के लिए प्रतिक्रिया करते हैं । पौधे और अन्य प्रकाश संश्लेषक जीव प्रकाश (आमतौर पर सौर ऊर्जा) को अवशोषित करने और इसे रासायनिक ऊर्जा में परिवर्तित करने के लिए क्लोरोफिल का उपयोग करते हैं| |

No part if the energy ever return to the sun,because passage of energy is concidered to be a transport.one waytwo waymultiwayany direction |
|
Answer» Answer: The PRODUCERS convert solar energy into chemical energy in the FORM of organic compounds. The primary consumers (HERBIVORES) derive their NUTRITION from the producers. According to the energy transfer law, only 10% of energy is transferred from one trophic level to the other. So, the energy that is captured by the producers does not revert back to the Sun and the energy transferred to the herbivores does not come back to the producers. It just keeps on moving to the next trophic level in a unidirectional way. That is why the flow of energy in the FOOD chain is always unidirectional/one way. |
