Human Demography: The study of age-structured populations Lab Preparation: Read the lab and be on time. There will be a quiz. Also‚ we’ll be riding a bus to the field location. If you want to join us for lab‚ don’t miss the bus! Bring your lab manual‚ a hard notebook or clipboard‚ paper and charcoal (for rubbings) and wear warm‚ possibly waterproof clothes. We’ll be outside for a good portion of the lab regardless of the weather. Background: Demography Demography is the descriptive study

A prominent Anglo-indian‚ Derozio played a major role in introducing western attitudes into Indian intellectual life. He taught literature and history at Hindu College‚ Calcutta and was perhaps the first nationalist poet of modern India. Drawing inspiration from French Revolution‚ he inspired his pupils to think freely and rationally‚ question all authority‚ oppose meaningless customs and traditions. He started a discussion group—the Academic Association—to enable interaction amongst students. He

Research The Chemical name for Baking Soda: Baking soda is sodium bicarbonate. The molecular formula of sodium bicarbonate is NaHCO3. What Baking Powder contains: Baking powder is a raising agent that is commonly used in cake-making. It is made from an alkali- bicarbonate of soda‚ and an acid- cream of tartar‚ plus a filler like corn flour or rice flour which absorbs moisture. Baking powder is a mixture of leavening agents (baking soda‚ acid salts) and inert ingredients (cornstarch‚ calcium
