integral proteins - Penetrate the hydrophobic interior of the lipid bilayer. Commerce via facilitated or active. peripheral protein - A protein loosely bound to the surface of a membrane or to part of an integral protein and not embedded in the lipid bilayer. Carbohydrate group -Linked with protein or lipids and function as adhesion. Cholesterol -Steroid common in cell membranes, also in many hormones. Functions as support make the membrane more rigid and less soluble. Structural protein ...

sensation - how sensory receptors receive and represent stimulus energies from the environment Perception - how we organize and interpret the sensory information, drawing meaning from the world around us neuron - a cell that conducts electrochemical signals and is the basic unit of the nervous system synesthesia - stimulation of one sense triggers another (feeling colors) Interneurons (association neurons) - neurons that carry messages from motor to sensory nerves myelin sheath - prevents ...

Biology 30 Alberta: The Senses Questions and Answers 100% Solved How are stimuli detected? By sensory receptors How does sensation occur? Electrochemical impulses arrive at cerebral cortex Sensory adaptation Process by which repeated, insignificant signals are filtered out What do photoreceptors do? Detect light (e.g. rods and cones in human eye) What do chemoreceptors do? Detect chemical signals (e.g. olfactory cells for smell, taste buds, internal detection of pH levels, etc.) What do mec...

Describe Passivation - correct answer Passivation is the formation of a protective oxide film on the surface reducing its chemical activity and its ability to corrode. Describe the following factors and how they affect corrosion: - correct answer • Oxygen: Oxygen increases the rate of corrosion. • Temperature: Corrosion usually accelerated with increasing temperature • Chemical Salts: Increase the rate of corrosion by increasing the efficiency of the electrolyte. • Humidity (or Wet...
