Answer the questions after read articles (Life Science) Article

Answer the questions after(prenominal) read articles (Life Science) - Article ExampleBased on these the basic organization of life was classified on a lower floor 5 major divisions namely Animalia, Plantea, Fungi, Protista and Monera. With the advent of new technologies and fossil records many scientists believe that commonwealth Protista and Fungi cannot constitute a separate lineage as higher classes of organisms are believed to bedevil evolved from these unicellular eukaryotes. Additionally the kingdom Monera which includes the prokaryotic life forms cannot be classified on with the others as there is a primary distinction between prokaryotes and the other eukaryotic organisms. The advent of sequencing has made the molecular sequences accessible which has in turn fuelled the need for a more formal taxonomical classification utilise the available molecular data. Hence these scientific breakthroughs have called for a new hierarchical system of classification.Archeabacteria ma tch eubacteria more closely on a molecular level. The evolution of photosynthetic eubacteria along with archea and possibly eukaryotes dates back to 3 to 4 billion years ago. Archeabacteria resemble prokaryotes in their cell cytology simply on the molecular level they resemble eubacteria. However, with the exception of some differences the archeabacterial molecules bear a close affinity to the eukaryotic counterparts.The Bt gene discovered from the organism Bacillus thuringiensis, has the ability to destroy corn borers such as caterpillars by damaging their guts. Hence this gene was isolated from the bacterium and introduced into corn. Other similar genetically circumscribed foods include tomatoes, rice and potatoes.The monarch caterpillar eats leaves of milkweed which is present in roadsides and edges of fields. The present acquire revealed that these caterpillars died after munching the milkweed leaves which contained Bt corn pollen. However, in California the government has p assed laws to protect the habitat of these monarch caterpillars referable to the increasing threats
