Beverly Hearst IB SL Physics Rate of Vaporization Design Lab Research Question: How does changing the surface area of a sample of water affect the time taken for the water to boil? Background: By changing the containers of the water‚ the surface area of the water is thus being modified as the same volume of water is spread out over smaller or larger surfaces. The measure being compared is the time each sample of water will take before it reaches the boiling point‚ 100 C°. The relationship

Antibodies are protein molecules which are produced in response to a specific pathogen. Each antibody is different. It’s a Y shaped protein that attaches to the antigen on a (bacteria) cell. Steps of immune response and creation of antibodies; 1. A specific antigen type is identified 2. A specific B lymphocyte is identified that can produce an antibody which will bind to the antigen (proteins on the pathogen) 3. The B lymphocytes and several identical B lymphocytes clone themselves via mitosis to rapidly

Robert Cormier explores the dark side of human nature in many of his novels for teenagers. What makes his treatment of this theme so effective‚ thought-provoking and‚ at times‚ chilling is his belief that evil is often to be found in the most unlikely of places.
