School ACTIVITY In 1828, the chemist Jacob Berzelius wrote that there are reasons to suppose that, in animals and plants, there are thousands of catalytic processes. He attributed to the "catalytic power" tissues of living organisms the ability to synthesize several kinds of chemical compounds. Regarding this "catalytic power", we can say that Berzelius was referring to vitamins? Justify your answer. SEARCH The application of genetic improvement techniques have contributed substantially to Brazilian researchers develop plant foods with better quality. Researchers such as geneticist Warwick Estevam Kerr (1922 -) and his team since the 1980s, selected varieties of lettuce and after several crossings obtained a surprising variety with increased content of pro-vitamin A in their leaves. Search more about this work and the contributions of these scientific research to society. One of the readings that you can perform is available on the website www.universia.com.br / html / materia / materia_dhii.html. With the knowledge presented and discussed so far, return the food groups of the first activity of the leaves and investigate the possibility of whether the food we consume daily are transgenic or not, or whether they are the result of years of breeding classic. SEARCH The new lettuce variety, with the proviso synthesize a high amount of pro-vitamin A would not be a new species of lettuce? That remains the species Lactuca sativa? What characterizes a species from the point of view of genetics: the presence of the same gene sequence or from the same external characteristics such as shape and number of leaves, leaf color, and type of, among other phenotypic traits? Search in biology textbooks and the Internet, and, subsequently, discuss with your colleagues. Remember that the activities developed with the technique of breeding began to develop long before Mendel's laws of heredity proposing. These laws were, and still are, used to explain how transmission occurs from genes to determine characteristics of a living being from one generation to another.

Škola AKTIVNOST U 1828, kemičar Jacob Berzelius napisao da postoje razlozi za pretpostavku da je, u životinjama i biljkama, postoje tisuće katalitičkim procesima. On pripisuje "snaga" katalitičkim tkivima živih organizama na sposobnost sintetizirati nekoliko vrsta kemijskih spojeva. Što se tiče ovog "katalitičku moć", možemo reći da Berzelius je mislio na vitamine? Opravdati svoj odgovor. TRAŽI Primjena genetskih poboljšanje tehnike su značajno pridonijelo brazilski znanstvenici razvijaju biljne hrane uz bolju kvalitetu. Istraživači poput genetičara Warwick Estevam Kerr (1922 -) i njegov tim od 1980, izabrane vrste salate, a nakon nekoliko prijelazima dobiti iznenađujuću raznolikost s povećanim sadržajem pro-vitamina u svojim listovima. Traži više o ovom poslu i doprinosima tih znanstvenih istraživanja na društvo. Jedan od čitanja koje možete izvesti je dostupan na web stranici www.universia.com.br / html / materia / materia_dhii.html. Uz poznavanje predstavljen i raspravljen dosad, vratiti skupine namirnica iz prve aktivnosti lišća i istražiti mogućnost je li hrana koju konzumiramo svaki dan se transgenetska ili ne ili da li su rezultat dugogodišnjeg uzgoja klasik TRAŽI Nova sorta salate, s tim sintetizirati visoku količinu pro-vitamina A, bi se nova vrsta salate? To ostaje vrste sativa lactuca Ono što karakterizira vrsta iz stajališta genetike: prisutnost iste genske sekvence ili s istim vanjskim obilježjima kao što su oblik i broj listova, lišća boje, te vrsta, među ostalim fenotipskih osobina? Traži u udžbenicima biologije i Interneta, a potom i razgovarati sa svojim kolegama. Sjetite se da su aktivnosti razvijene s tehnikom uzgoja počela razvijati mnogo prije Mendel predlaže zakone nasljeđivanja Ovi zakoni su bili, i još uvijek se, koristi se za prijenos objasniti kako se javlja iz gena utvrditi karakteristike živog bića s jedne generacije na drugu.
