Question

To govorcu n Question 1 2 pts So far, most genetically modified organisms (GMOs) are plants that are: any one of these things more herbicide-resistant more nutritious more pest-resistant o Question 2 2 pts Recombinant DNA technology is used to produce GMOs stem cells bacteria that can make human insulin all of these things

Answer 1

QUESTION 1. ANS. ANY OF THESE

GENENTICALLY MODIFIED ORGANISMSM ARE ORGANISMS WHOSE GENETIC MATERIAL IS MODIFIED ACOORDING TO HUMAN NEEDS.SO GENETICALLY MODIFIED PLANTS ARE PLANTS WHOSE GENETIC MATERIAL IS MODIFEID FOR HUMAN NEEDS LIKE MORE NUTRITIUS PLANTS , MORE PEST RESISITANT , MORE HERBICIDE RESISTANT , MORE TOLERANT TO ADVERSE CONDITIONS , PRODUCE MORE YIELD ETC.

QUESTION 2 . ANS. ANY OF THESE THINGS

RECOMBINANT DNA TECHNOLOGY IS THE JOINING TOGETHER OF TWO DNA MOLECULES OF DIFFERENT SPECIES TOGETHER . THIS RECOMBINANT DNA IS THEN INSERTED IN TO A HOST ORGAINISM TO CHANGE ITS CHARCTERISTICS SUCH A WAY THAT IT CAN BE USED FOR HUMAN NEEDS. FOR EXMAPLE WHEN RECOMBINANT DNA IS INSERTED IN TO HOST ORGANISM IT CAN PRODUCE HUMAN INSULIN.  IT CAN BE USED TO PRODUCE STEM CELLS. WHEN THIS ARTIFICIALLY PRODUCED RECOMBINAT DNA IS INSERTED IN TO A HOST ORGANISM IT BECOMES A GENETICALLY MODIFIED ORGANISM.

QUESTION 12. TURE.

ANALOGUS ORGANS ARE MORPHOLOGICALLY SIMILAR BUT ARE ANATOMICALLY DIFFERENT .FOR EXAMPLE WINGS OF BUTTERFLY AND BIRDS LOOKS ALIKE BUT THEY ARE ANATOMICALLY DIFFERENT. ANOTHER EXAMPLE IS POTATO AND SWEET POTATO. SWEET POTATO IS ROOT MODIFICATION AND POTATO IS STEM MODIFICATION.ANALOGUS STRUCTURES ARE A RESULT OF COVEREGNT EVOLUTION THAT IS THESE STRUCTURE FORMED AS A RESULT OF ADAPTATION FOR SIMILAR FUNCTIONS . FOR EXMAPLE WINGS OF BUTTERFLY AND BIRDS HAVE SILMILAR FUNCTION . THEY DONOT SHARE COMMON ANCESTRY.

QUESTION 13. ANS FALSE.

THERE ARE THREE DMAINS IN THE TREE OF LIFE THEY ARE ARCHAEA ,   BACTERIA AND EUKARYA.

THE FIRST TWO ARE PROKARYOTES WHICH DONOT HAVE A WELL DFEINED NUCLUES . ALL ORGANISMS WHICH HAS A NUCLEUS AND MEMBRANE BOUND ORGANLLS COME UNDER EUKARYA.

DOMIANS ARE ALSO KNOWN AS SUPER KINGDOMS.

QUESTION . 14 ANS. FALSE.

A PHYLOGENETIC TREE IS A DIAGRAMMATIC REPRESENTATION WHICH SHOWS EVOLUTIONARY RELATIOSHIP AMONG DIFFERENT ORGANISMS. USING PHYLOGENETIC TREE WE CAN UNDERSTAND HOW DIFFERENT SPECIES HAS EVOLVED FROM A COMMON ANCESTOR . A PHYLOGENTIC TREE DONOT SHOW HOW LONG A SPECIES HAS EXISTED.
