How can we achieve sustainability through food waste ? |
|
Answer» Answer: if this helps you please mark it as brainliest Explanation: GLOBALLY, FOOD worth $750 billion is lost or wasted each year throughout the entire supply CHAIN. Reducing food loss and waste could help to recover these economic losses and reduce financial burdens on the world’s most vulnerable PEOPLE. In Sub-Saharan Africa, one of the world’s poorest and most food-insecure regions, the World Bank estimates that just a 1 percent reduction in post-harvest losses could lead to economic gains of $40 million each year. And out of that $40 million, most of the benefits would go directly to the smallholder farmers growing the food. We cannot achieve SUSTAINABILITY with food waste |

मानव रूधिर परिसंचरण तंत्र का चित्र बनाइए। |
|
Answer» hey mate❤here is your answer Explanation: परिसंचरण तंत्र या वाहिकातंत्र (circulatory SYSTEM) अंगों का वह समुच्चय है जो शरीर की कोशिकाओं के बीच पोषक तत्वों का यातायात करता है। इससे रोगों से शरीर की रक्षा होती है तथा शरीर का ताप एवं PH स्थिर बना रहता है। अमिनो अम्ल, विद्युत अपघट्य, गैसें, हार्मोन, रक्त कोशिकाएँ तथा नाइट्रोजन के अपशिष्ट उत्पाद आदि परिसंचरण तंत्र द्वारा यातायात किये जाते हैं। केवल रक्त-वितरण नेटवर्क को ही कुछ लोग वाहिका तंत्र मानते हैं जबकि अन्य लोग लसीका तंत्र को भी इसी में सम्मिलित करते हैं। मानव एवं अन्य कशेरुक प्राणियों के परिसंचरण तंत्र, 'बन्द परिसंचरण तंत्र' हैं (इसका मतलब है कि रक्त कभी भी धमनियों, शिराओं, एवं केशिकाओं के जाल से बाहर नहीं जाता)। अकशेरुकों के परिसंचरण तंत्र, 'खुले परिसंचरण तंत्र' हैं। बहुत से तुच्छ (primitive ANIMAL) में परिसंचरन तंत्र होता ही नहीं। किन्तु सभी प्राणियों का लसीका तंत्र एक खुला तंत्र होता है। वाहिकातंत्र हृदय, धमनियों तथा शिराओं के समूह का नाम है। धमनियों और शिराओं के बीच केशिकाओं का विस्तृत समूह भी इसी तंत्र का भाग है। इस तंत्र का काम शरीर के प्रत्येक भाग में रुधिर को पहुँचाना है, जिससे उसे पोषण और ऑक्सीजन प्राप्त हो सकें। इस तंत्र का केंद्र हृदय है, जो रुधिर को निरंतर पंप करता रहता है और धमनियाँ वे वाहिकाएँ हैं जिनमें होकर रुधिर अंगों में पहुँचता है तथा केशिकाओं द्वारा वितरित होता है। केशिकाओं के रुधिर से पोषण और ऑक्सीजन ऊतकों में चले जाते हैं और इस पोषण और ऑक्सीजन से विहीन रुधिर को वे शिरा में लौटाकर हृदय में लाती हैं जो उसको फुप्फुस में ऑक्सीजन लेने के लिए भेज देता है। आंत्र से अवशोषित होकर पोषक अवयव भी इस रुधिर में मिल जाते हैं और फिर से इस रुधिर को अंगों में ऑक्सीजन तथा पोषण पहुँचाने के लिए धमनियों द्वारा भेज दिया जाता है। hope it helps u mark as brainliest n follow plz. |
