Explanation:

डोडो (रफस क्यूक्यूलैटस) एक विलुप्त उड़ान रहित पक्षी है जो हिंद महासागर में मेडागास्कर के पूर्व मॉरीशस के द्वीप के लिए स्थानिकमारी वाला था। डोडो के सबसे करीबी आनुवांशिक रिश्तेदार भी विलुप्त रोड्रिग्स सॉलिटेयर थे, दोनों कबूतरों और कबूतरों के परिवार की उपपरिवार रफैनी थे। डोडो का सबसे करीबी जीवित रिश्तेदार निकोबार कबूतर है। एक सफेद डोडो को कभी रियूनियन के पास के द्वीप पर मौजूद माना जाता था, लेकिन अब रियूनियन इबिस और सफेद डोडो के चित्रों के आधार पर भ्रम की स्थिति पैदा हो गई है।

सबफॉसिल अवशेष दिखाते हैं कि डोडो लगभग 1 मीटर (3 फीट 3 इंच) लंबा था और जंगली में इसका वजन 10.6–17.5 किलोग्राम (23-39 पाउंड) हो सकता है। जीवन में डोडो की उपस्थिति केवल 17 वीं शताब्दी के चित्र, चित्रों और लिखित खातों से ही स्पष्ट होती है। जैसा कि ये काफी भिन्न होते हैं, और केवल कुछ दृष्टांतों को ज्ञात नमूनों से खींचा गया है, जीवन में इसकी सटीक उपस्थिति अनसुलझी बनी हुई है, और इसके व्यवहार के बारे में बहुत कम लोग जानते हैं। हालांकि डोडो को ऐतिहासिक रूप से मोटा और अनाड़ी माना जाता रहा है, लेकिन अब यह माना जाता है कि इसके पारिस्थितिकी तंत्र के लिए इसे अच्छी तरह से अनुकूलित किया गया है। यह भूरा-भूरे रंग की परत, पीले पैर, पूंछ के पंखों के एक गुच्छे, एक ग्रे, नग्न सिर, और एक काले, पीले और हरे रंग की चोंच के साथ चित्रित किया गया है। यह अपने भोजन को पचाने में मदद करने के लिए गिज़र्ड पत्थरों का इस्तेमाल करता था, जिसके बारे में माना जाता है कि इसमें फल भी शामिल हैं, और माना जाता है कि इसका मुख्य निवास स्थान मॉरीशस के सूखे तटीय क्षेत्रों में जंगल रहा है।

How long does it take for a person's cells to all die after clinical death?
Blababa [14]
Clinical death is the medical term for cessation of blood circulation and breathing, the two necessary criteria to sustain human and many other organisms' lives.

It occurs when the heart stops beating in a regular rhythm, a condition called cardiac arrest.


Brain injuries start to accumulate almost immediately after Clinical Death.

Full recovery of the brain after more than 3 minutes of clinical death at normal body temperature is rare.

Usually brain damage or later brain death results after longer intervals of clinical death even if the heart is restarted and blood circulation is successfully restored.
Although loss of function is almost immediate, there is no specific duration of clinical death at which the non-functioning brain clearly dies.






The most vulnerable cells in the brain, CA1 neurons of the hippocampus, are fatally injured by as little as 10 minutes without oxygen.

However, the injured cells do not actually die until hours after resuscitation.

Brain failure after clinical death is now known to be due to a complex series of processes called Reperfusion Iinjury that occur after blood circulation has been restored, especially processes that interfere with blood circulation during the recovery period.

Hope this helps!!!

What adaptations allow deep sea creatures to survive in extreme environments essay?
hichkok12 [17]
The deep sea vent organisms or benthic organisms normally live in dark conditions because of no penetration of sunlight. These organisms in order to colonize ocean surface must develop photo sensory receptors and should adapt to the light conditions along with variation in temperatures and pressure in ocean currents.

How did the development of technology and academic rivalry influence the Human Genome Project?
olya-2409 [2.1K]
<span>The Human Genome Project had a very negative effect due to development in technology and academic rivalry. With knowledge came bitter rivalry and with technology came the tendency to become God. These angles greatly created negative impact about this project. The experts tried to create human clones, tissue engineering etc.  The scientists tried to analyze a person and get rid of any future disease that might attack them. Some people feel this is good while others feel that it is like distorting the natural process. </span>
