SU_BIO2071_W1_A2_Alimole_. A.doc. Exercise 1: Hanging-drop and wet-mount preparations How does true motility differ from Brownian movement? Brownian movement is the result of molecules of the suspending water bumping into the bacterium. This is an asymmetrical‚ spasmodic movement‚ which gives cells a vibrating look. This does not show proper motility. Correct motility is movement in a specific constant direction that shows winding and spinning. What morphological structure is responsible

The Effect of Osmosis on The Mass of Eggs Victoria Vu Biology October 22‚ 2013 Introduction & Hypothesis The membrane of an egg is composed of keratin (a type of protein)‚ which is semipermeable. This means only certain materials will be allowed to enter and exit through the egg’s membrane. The purpose of this experiment is study the process in which water molecules pass the egg membrane‚ osmosis. This experiment also gives insight on how other ‘semipermeable membranes’ work‚ like a

EXPERIMENT: Pressure drop over a bubble cap plate. AIM : This experiment is conducted in an experimental test ring in which the effect of the variation in vapor and liquid flow rates on the pressure drop across bubble cap plates is simulated using air and water to represent the vapor and liquid respectively. THEORY: In a pilot tube the relation between the gas velocity and pressure drop is Where‚ is the differential pressure as expressed in the head of the fluid flowing. Where‚ ’=level
