COMPLETE)BIOLOGY 442 ACTUAL EXAM TEST VIROLOGY QUESTIONS AND ANSWERS TEST 2024 UPDATE(CHAPTER 1-6) Lecture 1: Origin and History of Viruses 1) How did the of application of Koch’s postulates in the 1880’s lead to the discovery of viruses? a. Koch’s postulates correlated many diseases with their causing agent/organism. In the 1880’s, Koch’s postulates established four criteria to isolate the responsible disease-causing agent and correlate it to the effects that disease was ca...

Chapter 5 of Class 12 Chemistry explores coordination compounds, which consist of a central metal atom or ion bonded to surrounding ligands through coordinate covalent bonds. The chapter covers key concepts such as coordination number, oxidation states, and the geometries of these compounds. It delves into naming conventions, isomerism, and the role of ligands, including their classification as monodentate, bidentate, or polydentate. Additionally, the chapter examines the applications of coordin...

1. Metal-Carbon Bonds: - Organometallic compounds feature direct metal-carbon bonds. - Common ligands include alkyls, aryls, and carbonyls. 2. Classification: - Organometallic compounds are classified based on the type of metal-carbon bond, such as sigma bonds (σ) or pi bonds (π). 3. Reactivity: - Organometallic compounds often exhibit unique reactivity compared to organic compounds. - They can undergo nucleophilic and electrophilic reactions. 4. Applications: ...

Organometallic chemistry is a branch of chemistry that studies compounds containing metal-carbon bonds. These compounds often involve metals from groups 1 to 12 on the periodic table. Here's a brief overview of key aspects of organometallic chemistry: 1. Metal-Carbon Bonds: - Organometallic compounds feature direct metal-carbon bonds. - Common ligands include alkyls, aryls, and carbonyls. 2. Classification: - Organometallic compounds are classified based on the type of metal-c...
