Jawaban:36 C Gas belerang37 B. Punahnya vegetasi dan rantai makanan38. A Letusan adalah penyebab variabilitas genetik yang sangat terbatas pada seluruh ras manusia Penjelasan:ENGLISH → INDONESIAN Letusan tobaLetusan tobaSekitar 74.000 tahun yang lalu di pulau Sumatera, Indonesia, terjadi letusan gunung berapi yang sangat dahsyat yang terbukti menjadi bencana bagi umat manusia. .ilmuwan memperkirakan bahwa letusan itu mungkin telah mengeluarkan hingga 6.000 km3 magma batu yang dihancurkan dan gas belerang yang cukup untuk membentuk 5.000 megaton aerosol asam sulfat stratosfer. .penangguhan begitu banyak materi di atmosfer bumi mengakibatkan musim dingin vulkanik yang berlangsung sepanjang tahun, setiap tahun selama beberapa tahun. Penurunan suhu global yang parah memiliki efek bencana pada vegetasi dan rantai makanan yang bergantung padanya untuk bertahan hidup-termasuk manusia .Letusan tobaSekitar 74.000 tahun yang lalu di pulau Sumatera, Indonesia, terjadi letusan gunung berapi yang sangat dahsyat yang terbukti menjadi bencana bagi umat manusia. .ilmuwan memperkirakan bahwa letusan itu mungkin telah mengeluarkan hingga 6.000 km3 magma batu yang dihancurkan dan gas belerang yang cukup untuk membentuk 5.000 megaton aerosol asam sulfat stratosfer. .penangguhan begitu banyak materi di atmosfer bumi mengakibatkan musim dingin vulkanik yang berlangsung sepanjang tahun, setiap tahun selama beberapa tahun. Penurunan suhu global yang parah memiliki efek bencana pada vegetasi dan rantai makanan yang bergantung padanya untuk bertahan hidup-termasuk manusia ..para ilmuwan telah memeriksa kode genetik dari ras manusia yang tampaknya berbeda dan berjarak dan menemukan bahwa sebenarnya ada sangat sedikit variabilitas genetik di seluruh ras manusia. .bukti menunjukkan bahwa sesuatu terjadi pada kumpulan gen manusia sekitar 74.000 tahun yang lalu di mana hanya sangat sedikit manusia yang tetap hidup di planet ini (katakanlah 5.000 hingga 10.000), dan populasi saat ini telah berkembang dari beberapa genotipe selektif ini. .keberadaan kita dalam jumlah yang begitu besar hari ini (lebih dari 6 miliar kuat) adalah bukti kemampuan ulet kita untuk bertahan hidup.ANSWER BY RADITGANZ
