After the solution had been made we obtain about 5 ml of the Strawberry filtrate and added it to a clean test tube. Few milliliters of cold ethanol that had been stored in the freezer was added to the

HEAT GENERATED IN APPLIANCES Why do some appliances produce more heat than the others? Most appliances with high power rating are heating appliances.The heating appliances has a heating element like resistors. The resistorsconvert electrical energy into light and thermal energy . It depends on the resistance of material if how much heat can be produced from electricity. Those devices who produced heat‚ the Nichrome wire is an element who is responsible for heating . when we say nichrome

reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent. Within the Agnostic

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid?

It was found some ways to control bacterial growth were disinfection‚ sterilization‚ antisepsis‚ sanitization‚ moist and dry heat‚ filtration‚ and radiation; just to name a few. The specific method used for control depends on various circumstances. PROCEDURE First‚ you want to place your test tubes on the bench; one being an unknown labeled as GrowthLab1 and the other is
