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

PATTERNS IN NATURE – Summary Notes 1. ORGANISMS ARE MADE OF CELLS THAT HAVE SIMILAR STRUCTURAL CHARACTERISTICS 1.1 Outline the historical development of the cell theory‚ in particular‚ the contributions of Robert Hooke and Robert Brown The Cell Theory states that: All living things are made of cells (Theodor Schwann & Matthias Schleiden) Cells are the basic structural and functional unit of organisms (Theodor Schwann) All cells come from pre-existing cells (Rudolf Virchow) The historical

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

The community forms the living‚ or biotic part of the ecosystem. Energy‚ Minerals‚ Nutrients and water from the non-living or abiotic components. 1. Inorganic substances (C‚N‚CO2‚H20 etc) incolved in material cycles. 2. Organic compounds (Proteins‚ Carbohydrates‚ lipids‚ humic substances etc.)

Evaluate the impact of care in the community for adults with Mental Health problems. Care in the community is where a patient is no longer detained nor sectioned within a hospital institution. However‚ there must be at least three practitioners agreeing that it is necessary for the patient to be released into the community. Adults who may suffer from mental health problems can ask to be cared for within the community. Patients and their families are now more educated with a sense of empowerment
