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।

During metamorphosis, a tadpole's tail is reduced in size by the process of ______. A. regeneration B. apoptosis C. oxidative ph
jolli1 [7]

The process of apoptosis, I believe, is when the tadpole's tail is reduced in size during metamorphosis.

In most animal phyla, metamorphosis actually takes place in conjunction with morphological, ecological, and physiological changes.

Marine invertebrates' larva behaves as a drifting tiny creature in the ocean, expanding its habitat distribution to find the best location for its survival.

When muscle cells undergo apoptosis, which is the final stage of their metamorphosis, they are split into membrane-bound muscle fragments and consumed by macrophages.

As a tadpole becomes a frog, apoptosis occurs. The cells in its tail are induced and it will be lost.

If ammonia is used as an energy and electron source by a bacterium, that bacterium would be considered a ___.
zhuklara [117]

If a bacterium uses ammonia as an energy as well as electron source, it is classified as lithotrophic chemotrophic.

<h3>Descriptive terms for lithotrophic chemotrophic:</h3>

Humans, fungi, and also many prokaryotes are chemotrophs that get their energy from organic chemicals. Lithotrophs are chemotrophs that obtain energy from inorganic substances such as hydrogen sulfide (H2S) as well as reduced iron. Lithography is a microbiological phenomenon that is unique in the globe.

<h3>What is the difference between chemoautotrophs and chemolithotrophs?</h3>

Chemotrophs are creatures that get energy from their surroundings by oxidizing electron sources. These compounds might well be organic (chemoorganotrophs) or inorganic (chemoorganotrophs) (chemolithotrophs). The term chemotroph is used in contrast to phototroph, which uses solar energy.
