Q1. In the human population, the Rh antigen is present on the red blood cells of approximately what percentage of individuals (i.e. who are Rh positive)?
मानव जनसंख्या में, लाल रक्त कोशिकाओं पर Rh प्रतिजन (एंटीजन) लगभग कितने प्रतिशत व्यक्तियों में उपस्थित होता है (अर्थात् जो Rh धनात्मक हैं)?
- A. About 95 per cent / लगभग 95 प्रतिशत
- B. About 80 per cent / लगभग 80 प्रतिशत
- C. About 65 per cent / लगभग 65 प्रतिशत
- D. About 50 per cent / लगभग 50 प्रतिशत
Solution
The majority of humans, nearly 80 per cent, carry the Rh antigen on their RBCs and are said to be Rh positive.
अधिकांश मनुष्यों, लगभग 80 प्रतिशत, की लाल रक्त कोशिकाओं पर Rh प्रतिजन होता है और उन्हें Rh धनात्मक कहा जाता है।
Q2. The human heart is protected by a double-walled membranous sac containing a fluid that reduces friction during heartbeats. This sac is called the:
मानव हृदय एक द्विभित्ति (दोहरी दीवार वाले) झिल्लीदार थैली द्वारा सुरक्षित रहता है, जिसमें एक तरल पदार्थ होता है जो हृदय-स्पंदन के दौरान घर्षण को कम करता है। इस थैली को कहते हैं:
- A. Pleura / प्लूरा
- B. Peritoneum / पेरिटोनियम
- C. Mesentery / मेसेंट्री
- D. Pericardium / पेरिकार्डियम
Solution
The heart lies within the pericardium, a double-walled membrane enclosing pericardial fluid. The pleura surrounds the lungs and the peritoneum lines the abdominal cavity.
हृदय पेरिकार्डियम के भीतर स्थित होता है, जो एक द्विभित्ति झिल्ली है जिसमें पेरिकार्डियल तरल बंद रहता है। प्लूरा फेफड़ों को घेरता है और पेरिटोनियम उदर गुहा को आस्तरित करता है।
Q3. During blood coagulation, the enzyme thrombin acts upon which plasma protein to convert it into the fibrin threads that form the clot?
रक्त स्कंदन के दौरान, एंजाइम थ्रोम्बिन किस प्लाज्मा प्रोटीन पर क्रिया करके उसे फाइब्रिन तंतुओं में परिवर्तित करता है जो थक्के का निर्माण करते हैं?
- A. Globulin / ग्लोब्युलिन
- B. Prothrombin / प्रोथ्रोम्बिन
- C. Albumin / एल्ब्युमिन
- D. Fibrinogen / फाइब्रिनोजन
Solution
Thrombins catalyse the conversion of the soluble plasma protein fibrinogen into insoluble fibrin threads, which form the network of the clot. Prothrombin is the precursor of thrombin itself.
थ्रोम्बिन घुलनशील प्लाज्मा प्रोटीन फाइब्रिनोजन के अघुलनशील फाइब्रिन तंतुओं में परिवर्तन को उत्प्रेरित करता है, जो थक्के का जाल बनाते हैं। प्रोथ्रोम्बिन स्वयं थ्रोम्बिन का पूर्वगामी है।
