Assignments in Science Class X (Term II) 4 Carbon and its Compounds IMPORTANT NOTES 9. Unsaturated organic compounds : Organic compounds in which a double or a triple bond exists between two carbon atoms in a carbon chain‚ are called unsaturated organic compounds. 10. Hydrocarbons : Organic compounds which contain only carbon and hydrogen atoms are called hydrocarbons. 11. Straight chain hydrocarbons : Hydrocarbons‚ in which all the carbon atoms are linked to one another in a straight chain

its #2 carbon atom (designated 2’)‚ and ribose has a hydroxyl group atom there. Deoxyribose-containing nucleotides are the monomers of DNA RNA Nucleotide [pic] The left picture shows the nucleotide unit of RNA. Nucleotides differ from nucleosides in that they have phosphate groups. Nucleotides can exist in the mono-‚ di-‚ or tri-phosphorylated forms. The most common site of phosphorylation of nucleotides found in cells is the hydroxyl group attached to the 5’-carbon of the

Molecular modelling is the general term used to describe the use of computers to construct molecules and perform a variety of calculations on these molecules in order to predict their chemical characteristics and behaviour. The term molecular modelling is often used synonymously with the term computational chemistry. Computational chemistry is a broader term‚ referring to any use of computers to study chemical systems. Some chemists use the term computational quantum chemistry to refer to the use

MOLECULAR MODELING 1. Objectives ● Predictthe shape of identified compounds; ● Construct molecular models of identified compounds; and ●Determine the molecular structure of identified compounds. 2. Theory Building models of molecules are useful for visualizing how atoms are connected in three-dimensional space called molecular geometry‚ which is best predicted by Valence-Shell Electron-Pair Repulsion (VSPER) theory. The following are the sets of rules summarizing thsi theory: ●

Speech I. The history of molecular gastronomy Molecular gastronomy is a new discipline about food science. This science investigates‚ explains and makes practical use of the physical and chemical transformations of ingredients that take place while cooking. But the truth is‚ using this science in cooking is not new. Pioneer Professors Evelyn G. Halliday and Isabel T. Noble: they said in their book “The main purpose of this book is to give an understanding of the chemical principles upon

What is Cultural Diversity? What is cultural diversity? Diversity is nothing more than a difference from the majority. In any culture there is a majority and many minorities. Culture is a set of norms that set standards for a society of what is acceptable behavior. In every culture there are basic standards for social interaction such as personal space distance‚ eye contact‚ amount of body language displayed in public‚ negotiating style‚ etc. In America‚ we stand about eighteen inches apart when

Molecular gastronomy Transglutaminase (TG) is a naturally occurring enzyme in plants‚ animals‚ and bacteria. Enzymes are proteins that act as catalysts in chemical reactions; they speed up reactions and make reactions occur that otherwise wouldn’t. Although TG is a newcomer to the kitchen‚ cooks have used enzymes for thousands of years. Enzymes in papaya‚ for instance‚ are traditionally used as meat tenderizers. The enzyme rennet is used to curdle milk when making cheese. Enzymes that break down

MOLECULAR FARMING INTRODUCTION Biotechnology in agriculture has two categories: 1. “Improvements” to existing livestock and crops‚ and 2. Development of entirely new uses for both animals and plants (biopharming). “Improvements"‚ include ‘input traits’ such as crops with extra resistance to insect attack‚ improved weed control‚ increase the plants tolerance to cold‚ drought and other environmental factor. Ex "Roundup ready" soya‚ "Starlite" corn‚ or "Frost-tolerant" tomatoes. WHY PLANTS

Holding crisis? What role did the “Open Work” environment play in the case? Analyze the issues using Chapter 3’s cross-cultural dimensions from the Globe and Hofstede studies‚ differences in high versus low context cultures‚ etc. How do you develop a global mindset for this team? What role did diversity play on this team (ch. 3 and 4)? What should James do in the short and long-term? Relate this case to your co-op or study abroad experience.
