Prophase Iप्रोफ़ेज़ I

Anaphase IIएनाफ़ेज़ II

Telophase Iटेलोफ़ेज़ I

Metaphase IIमेटाफ़ेज़ II

द्वितीयक अंडाणु अर्धसूत्रीविभाजन II के मेटाफ़ेज़ II में रुक जाता है और निषेचित शुक्राणु के प्रवेश पर ही विभाजन पूरा करता है।

What biochemical change immediately prevents polyspermy when a sperm penetrates the human egg?

जब एक शुक्राणु मानव अंडे में प्रवेश करता है तो कौन सा जैव रासायनिक परिवर्तन तुरंत पॉलीस्पर्मी को रोकता है?

Cortical reaction inducing hardening and alteration of the Zona Pellucidaज़ोना पेलुसिडा के सख्त होने और परिवर्तन को प्रेरित करने वाली कॉर्टिकल प्रतिक्रिया

Immediate release of second polar bodyदूसरे ध्रुवीय पिंड की तत्काल रिहाई

Luteinization of corona radiataकोरोना रेडियेटा का ल्यूटिनाइजेशन

Correct Answer: Option B

Explanation:

Sperm contact triggers an intracellular Ca^{2+} wave and exocytosis of cortical granules (cortical reaction), which chemically modifies and hardens the zona pellucida, blocking additional sperms.

शुक्राणु संपर्क एक इंट्रासेल्युलर Ca^{2+} तरंग और कॉर्टिकल ग्रैन्यूल (कॉर्टिकल प्रतिक्रिया) के एक्सोसाइटोसिस को ट्रिगर करता है, जो रासायनिक रूप से ज़ोना पेलुसीडा को संशोधित और कठोर करता है, जिससे अतिरिक्त शुक्राणु अवरुद्ध हो जाते हैं।

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Focused chapter-wise CBT practice builds the speed, mental stamina, and analytical discipline required to ace CUET, JEE Main, NEET UG, NDA, CA Foundation, and College Entrance Exams.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन
