SBI4U-C 1 Lesson Introducing Biochemistry 1 Lesson 1 Biology SBI4U-C Introduction If you think about it‚ living things are made up of chemicals. The cells‚ tissues‚ organs‚ and organ systems that together make up a functioning organism are all the product of interacting chemicals. In order to understand how the organism functions‚ you must also recognize how these chemicals function. The study of the chemicals that are involved in living things is known as biochemistry

EVAPORATION. When plants give off water vapor‚ it’s called transpiration. When water evaporates‚ it rises into the cooler air‚ collects‚ and forms clouds. There‚ the water vapor molecules cool down and change back into liquid water. This is called CONDENSATION. As more and more water vapor cools into the clouds‚ the water droplets that form the clouds become larger and larger. These droplets get so big that the atmosphere can no longer hold them up. The droplets fall from the sky. PRECIPITATION is the

Goldwater will be poured into the prepared mold inside‚ and Jin condensation temperature is gradually receded‚ and then turn over the mold‚ pour out the gold products‚ so it becomes a glittering

keeps urine in the bladder as long as it is in need of water‚ when it needs the water; the blood absorbs urine again and pushes it into the stomach‚ especially bacteria converts urine to protein and water. In addition‚ Camel’s nose is doing the condensation of water vapor that comes out with the exhaled air‚ so it is the only animal that restores the water in the air that comes out of it.Camel has the ability to drink sea water because the kidneys get rid of excess salts. The camel drinks profusely

excessive spending of energy due to that only to increase spending money in energy bills. On the other hand‚ insulation installed to your house lowers burning of fossil fuel‚ CO2 emissions and energy bills. At the same time‚ insulation aids in reducing condensation and moisture build up which was the main purpose of keeping spaces inside the walls. Insulated walls retard the rate of escaping heat‚ retaining the heat inside the home as much as possible.

"Multistep synthesis" refers to the procedure in which the product of one reaction serves as the starting material in the subsequent reaction. The multistep synthesis of benzilic acid begins with a conversion benzaldehyde to benzoin through a condensation reaction. The benzoin then oxidizes into benzil‚ which undergoes rearrangement to give benzilic acid. Benzoin Synthesis * When two benzaldehyde molecules condense in the presence of thiamine‚ it leads to the formation of a molecule of benzoin

The winds weaken with height. · The centers of the hurricane are warmer than their surroundings · They form under weak high altitude winds. · The air also sinks at the center of a hurricane and the main energy source is the latent heat of condensation. · They weaken rapidly over land. Definition: A Hurricane is an intense tropical weather system with a well defined circulation and maximum sustained winds of 74 mph (64 knots) or higher. In the western Pacific‚ hurricanes are called "typhoons

base-catalyzed formation of chalcone and its derivatives. [7‚ 8‚ 9] Two alternative mechanisms have been advanced for the reaction of benzaldehyde with acetophenone in the presence of a basic catalyst. 5 The formation of chalcone by the acid catalyzed condensation of acetophenone and benzaldehyde has been studied [10]. The following mechanism seems to be operating- 6 Importance of chalcones [1]They have close relationship with flavones‚ aurones‚ tetralones and aziridines. [2]Chalcones and their derivatives

The experiment’s objectives were to synthesize alum‚ test for various ions in alum‚ and form crystals in aqueous alum solution. The alum was synthesized from aluminum foil and run through a filtration system to isolate the alum. 2 Al(s) + 2 KOH + 22 H2O + 4 H2SO4 → 2 KAl(SO4)2●12H2O(s) + 3 H2(g) Its composition was analyzed using two precipitation tests and two flame tests. Three methods for growing crystals were then set up for observation next lab. Theoretical yield and percent yield: The theoretical
