In your own words, describe the purpose and process of translation. The purpose of translation is… The process of translation is
kondaur [170]

Answer:

the purpose of the translation is to make proteins. proteins are responsible for making bones, muscles, cartilage, skin and blood. proteins are synthesized from the information in a mRNA.

Process of translation

it happens in 3 phases

  • initiation: the small ribosomal subunits binds to the start of the of the mRNA sequence. then a tRNA molecule carrying the amino acid methoionine binds to start codon of the mRNA sequence. after that large ribosomal subunit binds to form the complete intiation complex.
  • elongation: the ribosome continues to translate each codon in turn each corresponding amino acid is added to the growing chain and linked via bond called peptide bond. elongation continues untill all the codons are read.
  • termination: it occurs when the ribosome reaches a stop codon. since there is no tRNA molecules that can recognise these codons the ribosome recognises that translation is complete.

after these 3 phases a new protein is realeasd

Explanation:

answer is self explanatory

How might the management of nonrenewable resources be different fron the management of renewable resources?
Elden [556K]

Nonrenewable resources and found it fixed amount hence not managing properly will lead to full use of it and cannot be replaced

Explanation:

  • Nonrenewable resources are found in the ground and they are the natural resources created by nature
  • It includes fossil fuels, like natural gases, oil, coal, etc and also the minerals used for making metals
  • These natural resources have taken more than human's life span to form, up to million years. Hence, replacing of these natural resources are not possible
  • Renewable natural resources are trees, water, air. These resources can be recycled and they are also circulating in the atmosphere in the form of a cycle.
  • Hence, nonrenewable resources should be managed properly for it last for the coming generations.

Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to body tissues. People with hemoglobin levels les
Pani-rosa [81]

Answer:The Null hypothesis state that the mean hemoglobin level for all the children in Jordan is 12g/dl.

While the Alternative Hypothesis state that the mean hemoglobin level for all the children in Jordan is less than 12g/dl

Explanation:

The Null hypothesis H0: This is the hypothesis that state that there is no statistical difference between the two variables in the hypothesis. It is the hypothesis that the researcher is work to nullify.

The Alternative hypothesis H1: This is the hypothesis that states there is a statistically difference between two variables.

Studying the folding patterns of protein molecules can help microbiologists better understand cellular processes as well as some
xz_007 [3.2K]
The best answer in this case is C, "the researchers applied creativity to solve a problem in running an experiment".

Distributing the computing load across the global community by sharing processing power is a creative response to tackle the challenge in simulating protein folding for the experiment. This does not change or reduce the scientific merits of the experiment, so we can discount the first two answers (a & b). Answer d talks about well established scientific techniques, although the question wasn't really centered around the specific techniques, so it's not as relevant an answer as C.

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।
