AP Biology August 23‚ 2012 Egg Osmosis Lab Definition of osmosis: The diffusion of water across a selectively permeable membrane from high to low concentrations Hypothesis: If I place an egg in vinegar‚ then the outer layer of the egg is going to become slimy and look like rubber. It will also become larger and bubbles will form on and around the egg. Hypothesis: If I place an egg in corn syrup‚ then the egg will become small and the outer layer will not look like rubber any longer. Day one:

This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between

AP Bio p. 6 December 8‚ 2011 AP Biology Lab 5: Cellular Respiration Introduction/Lab Objective: In this lab we are testing how the process of cellular respiration is affected by temperature‚ and also how it is different between germinating and non-germinating peas. Cellular respiration is a catabolic process (breaks down organic material into usable cell energy) that produces ATP. The electron receivers are inorganic. Cellular respiration releases energy from organic material through chemical

B6 - The Brain and Mind - 6 Mark Question Practice A. Neurones are specialised cells transmitting nerve impulses. There are two types of neurones; Sensory cells‚ which send impulses from the receptor to the central processing centre and the motor neurones‚ transmit impulses from the brain and spinal cord to the effector cell that will respond to the stimulus. Impulses flow along thin tubes of cytoplasm. In the sensory neurones‚ the cell body is located in the middle and two tubes

Drew Staples 6/12/14 Properties of water Question Does mixing water with other substances change it’s boiling point. Research The boiling point of a liquid is when the temperature causes the vapor pressure to be equal to the air. Air density will change waters boiling point. High altitudes give water a lower boiling point. Hypothesis If the water is less dense then it will boil faster and the boiling point will be lower.

Aim: To investigate the effect of skin sensitivity in response to cold temperature in different parts of the body by timing the maximum amount of time in which ice-pack can be held to that area. Hypothesis: If the layer of skin is relatively thin‚ the nerve response to cold will be the fastest‚ increasing the skin’s sensitivity. This therefore means that the fastest responses to cold will be in the face‚ and specifically the nose. The skin consists of 3 main layers; the epidermis‚ dermis and
