Biyoloji Ödev Yardımı

Biyoloji öğrenmenin en zorlu kısmı, öğrencilerin biyolojinin mikroskobik dünyasını anlamalarını, hücrelerin içine nasıl girip genleri ve molekülleri nasıl keşfedeceklerini nasıl sağlayacaklarıdır. Ancak bilgi teknolojisinin gelişmesiyle birlikte, ne kelimelerin ne de resimlerin biyoloji konularını tam olarak açıklayamadığı durumlarda biyoloji ödevi yardımı önemli bir rol oynayabilir.

QuestionAI, çeşitli deneyler ve ilgili alıştırmalar dahil olmak üzere, yaygın biyoloji soruları yardımcısından temel olarak farklı olan, biyoloji bilgisini öğrenmenize ve uzmanlaşmanıza yardımcı olan bir çevrimiçi biyoloji öğrenme yazılımıdır. Burada, bilgi noktalarını öğrenmek ve anlamak için sığdan derine, katman katman deneysel senaryoları yeniden oluşturmak için deneyleri simüle edebilirsiniz.

In the mountains of Brazil, Barbacenia tomentosa and Barbacenia macrantha-two plants in the Velloziaceae family -establish themselves on soilless nutrient-poor patches of quartzite rock. Plant ecologists Anna Abrahão and Patricia de Britto Costa used microscopic analysis to determine that the roots of B tomentosa and B. macrantha which grow directly into the quartzite, have clusters of fine hairs near the root tip; further analysis indicated that these hairs secrete both malic and citric acids. The researchers hypothesize that the plants depend on dissolving underlying rock with these acids,as the process not only creates channels for continued growth but also releases phosphates that provide the vital nutrient phosphorus. 12 Mark for Review Which finding, if true, would most directly support the researchers' hypothesis? A Other species in the Velloziaceae family are found in terrains with more soil but have root structures similar to those of B.tomentosa and B. macrantha, B Though B. tomentosa and B. macrantha both secrete citric and malic acids each species produces the acids in different proportions. C The roots of B.tomentosa and B. macrantha carve new entry points into rocks even when cracks in the surface are readily available. D B. tomentosa and B.macrantha thrive even when transferred to the surfaces of rocks that do not contain phosphates.

For many years, the only existing fossil evidence of mixopterid eurypterids-an extinct family of large aquatic arthropods known as sea scorpions and related to modern arachnids and horseshoe crabs -came from four species living on the paleocontinen t of Laurussia. In a discovery that expands our understanding of the geographical distribution of mixopterids, paleontologist Bo Wang and others have identified fossilized remains of new mixopterid species, Terropterus xiushanensis, that lived over 400 million years ago on the paleocontinent of Gondwana. Mark for Review According to the text.why was Wang and his team's discovery of the Terropterus xiushanensis fossil significant? A The fossil constitutes the first evidence found by scientists that mixopterids lived more than 400 million years ago. B The fossil helps establish that mixopterids are more closely related to modern arachnids and horseshoe crabs than previously thought. C The fossil helps establish a more accurate timeline of the evolution of mixopterids on the paleocontinent.of Laurussia and Gondwana. D The fossil constitutes the first evidence found by scientists that mixopterids existed outside the paleocontinent of Laurussia.
