Answer : 1. "नाइट्रोजन"
Explanation :
पौधों के लिए आवश्यक तत्वों के संदर्भ में "ओवरडोज़" शब्द पोषक तत्वों की अधिकता या असंतुलन का सुझाव देता है, जो पौधों के स्वास्थ्य पर नकारात्मक प्रभाव डाल सकता है। दिए गए विकल्पों में से:
(ए) नाइट्रोजन
स्पष्टीकरण:
जबकि पौधों की वृद्धि के लिए सभी पोषक तत्व आवश्यक हैं, नाइट्रोजन की अधिकता या अत्यधिक उपयोग (विकल्प ए) पोषक तत्वों के असंतुलन, पर्यावरण प्रदूषण और कुछ बीमारियों के प्रति संवेदनशीलता में वृद्धि जैसी समस्याओं को जन्म दे सकता है। अत्यधिक नाइट्रोजन तेजी से वनस्पति विकास का कारण बन सकता है, लेकिन यह पौधों के स्वास्थ्य के अन्य पहलुओं, जैसे जड़ विकास, फूल और समग्र लचीलेपन पर नकारात्मक प्रभाव डाल सकता है।
पौधों के इष्टतम विकास के लिए संतुलित पोषक तत्व प्रबंधन महत्वपूर्ण है, और पोषक तत्वों के असंतुलन और पौधों के स्वास्थ्य पर संभावित नकारात्मक प्रभावों से बचने के लिए प्रत्येक पौधे की प्रजाति की विशिष्ट आवश्यकताओं और मिट्टी की स्थितियों पर विचार करना महत्वपूर्ण है।

Answer : 3. "(24-1)(23-1)25"
Explanation :
Answer: C) C Explanation: It is explicitly given that all the 4 black balls are different, all the 3 red balls are different and all the 5 blue balls are different. Hence this is a case where all are distinct objects. Initially let's find out the number of ways in which we can select the black balls. Note that at least 1 black ball must be included in each selection. Hence, we can select 1 black ball from 4 black ballsor 2 black balls from 4 black balls.or 3 black balls from 4 black balls.or 4 black balls from 4 black balls. Hence, number of ways in which we can select the black balls = 4C1 + 4C2 + 4C3 + 4C4= 24-1 ........(A) Now let's find out the number of ways in which we can select the red balls. Note that at least 1 red ball must be included in each selection. Hence, we can select 1 red ball from 3 red ballsor 2 red balls from 3 red ballsor 3 red balls from 3 red balls Hence, number of ways in which we can select the red balls= 3C1 + 3C2 + 3C3=23-1........(B) Hence, we can select 0 blue ball from 5 blue balls (i.e, do not select any blue ball. In this case, only black and red balls will be there)or 1 blue ball from 5 blue ballsor 2 blue balls from 5 blue ballsor 3 blue balls from 5 blue ballsor 4 blue balls from 5 blue ballsor 5 blue balls from 5 blue balls. Hence, number of ways in which we can select the blue balls= 5C0 + 5C1 + 5C2 + … + 5C5= 25..............(C) From (A), (B) and (C), required number of ways= 2524-123-1
