Anisha Malhotra Prof. Lovett Lab Report # 4 Experiment 7&8 1 Bacterial Growth and One Step Burst - T7 Phage I. INTRODUCTION: These experiments helped us learn the factors that were involved in the growth of the bacteria that increased our study towards their genetic‚ physical and metabolic characteristics. We used Escherichia coli and Bacteriophage T7 to identify and analyze their identical life cycle and replication that was involved in their process of growth. As‚ growth for any bacteria

Animal Diversity The number of animal varieties familiar to us is vast as the animal world is diverse. Each distinct variety or type of animals is recognized by scientist as a species. Animals of most species are free-living forms but of others are parasitic in bodies of other animals or even plants. According to their habitats animals are divided into the following types Aquatic animals :- They live in water . Animals living in sea water are called marine & those live in river‚ponds‚streams

Structural Isomers • molecules with the same molecular formula but with different arrangements of atoms • differences in the shape of isomers lead to differences in their physical & chemical properties • For example‚ galactose‚ glucose and fructose have the same molecular formula (C₆H₁₂O₆) but different structures (figure 6 page 30) • glucose itself has 3 different structural isomers in dry state‚ glucose has a linear structure‚ but when dissolved in water‚ the molecules fold on itself
