Ques 1.

Explain how the principles of evolutionary biology account for antibiotic resistance in bacteria and highlight its broader applications in science and society.

Ques 2.

Describe how the Big Bang theory, formation of Earth, and the concept of chemical evolution together explain the origin of life on our planet.

Ques 3.

Explain the key features and representation of phylogenetic trees, including nodes, branches, root, terminal nodes, outgroup, scaled (phylogram) and unscaled (cladogram) trees, rooted and unrooted trees, polytomy, and monophyletic, paraphyletic, and polyphyletic groups.

Ques 4.

Describe the key features, variability, and biological significance of bacterial genomes, including operons, plasmids, PHX genes, and adaptations in Deinococcus radiodurans.
