This bombing became the largest criminal investigation that was led by the smallest police force. (CIA) The New York bound flight fell out of the sky being in the air less than 40 minutes

Aerobic Respiration Breaking down glucose to release energy Products are Carbon dioxide and water Diffusion is … the movement of molecules from a region of high concentration to a low concentration until the concentration is equal. Role of a human circulatory system: Diffuse In – oxygen (O2)‚ dissolved food (glucose) and water (H2O) Diffuse Out – carbon dioxide (CO2)‚waste and water(H2O) Respiration – releasing energy in cells Breathing – getting air into and out of your body

Experiment 8.1 Yes there was a change because with the starting snail population there was a great variation from 1-7. After the crab began eating only the snails with the thickest shells survived. The snails with the thinnest shells were eaten by the crab. Only snails with shell thickness 4-7 were left after the crab had their meal. The original snails with thickness 1-3 were eliminated from the population by the crab. The crab will usually try to expend as little enrgy as it can to maximaize its

Extended experimental investigation: effects on membranes of environmental stress Background It is not possible to observe membranes directly‚ so this investigation is an indirect study of the effects of different substances and treatments on living beetroot cells. Beetroot cells have been chosen for this activity because each beetroot cell has a large central vacuole bounded by a membrane (Figure 1). Contained in the vacuole is the red pigment anthocyanin‚ which gives the beetroot its
