Protostomes develop a mouth first and then an anus. This is the difference between protostomes and deuterostomes.

In protostome development, there is a spiral radical and indeterminate cleavage. The blastopore becomes the mouth and the coelom forms from the mesoderm.

In deuterostomes development, radial and indeterminate cleavage takes place. The blastopore is the new anus and the coelom forms from budding off the wall of the archenteron.

Explain the difference between sexual reproduction and asexual reproduction. Explain either an advantage or disadvantage for
ira [324]

In asexual reproduction, reproductive organs aren't used but they're used.

advantage of sexual- A lot of genetic variation. since they have DNA of two parents. they can survive more and adapt more.

disadvantage of asexual- diversity is limited. Since the organism only gets the DNA of one parent, they wouldn't be able to really survive if something happened.They would easily be extinct.

Sorry I can't really cone up with better words but I hope you get the idea. it all comes down to natural selection really if you've learned about it. Hope it helped!!!

10 lines about any extinct animal in hindi
Archy [21]

Answer:

hi

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।

galina1969 [7]

Answer:

The student is wrong, spermatozoa are germinal cells and therefore mitochondrial mutations (likewise genomic nuclear mutations) are inherited by offspring

Explanation:

Although the probabilities of inheriting a mutation from a single sperm cell are low, it since an organism produces millions of sperm cells throughout its life span, the mutations in the germinal cells (i.e., sperms and ovules) are inherited by offspring

Which statement BEST describes the most likely reason that swimming in a group can help fish
masya89 [10]

The statement 'fish are able to swim faster in a group to avoid being caught by the predator' BEST describes the most likely reason that swimming in a group can help fish avoid a larger predator.

<h3>What is an adaptation?</h3>

An adaptation is an evolutionary strategy to increase the chances of surviving and reproducing in a given environment.

In this case, swimming in a group can minimize friction in the aquatic environment and thus swim faster.

Evolutionary strategies and adaptations may also be individual, but they always have the same objective.
