38. The graphs to the right (beak sizes of two bird species on 3 islands) are evidence of Pinta Marchena 40 A a. character replacement as a result of predation b. character displacement as a result of drought c. character dislocation as a result of evolution d. character assassination by predation e. character displacement by competition 20 G. G. fortis 12 fuliginosa 10 14 Daphne 39. Graph A shows that that a. the two species overlap in niche on the island Pinta Marchena; the two species do not overlap in niche on the other two islands while Graph B shows 20 В G. fortis 10 12 14 b. the two species do not overlap in niche on the island Pinta Marchena; the two species overlap in niche on the other two islands Los Hermanos 40 c. the two species compete for food in the island Pinta Marchena; the two species compete on the islands Daphne and Los Hermanos d. this is the site of origin for the two species; each of these islands were later colonized by the species e. Darwin correctly identified species on Pinta Marchena; he mis-identified them elsewhere 20 G. fuliginosa 10 12 14 Beak size (mm) Percentage of individuals of each size class
Anatomy and Physiology of Special Sensory Organs
Sensory organs can be labeled as special sensory structures that permit sight, hearing, odor, and flavor. Sensory structures permitting proprioception, touch, thermal, and pain perception can be classified as more advanced sensory organs. The sensory neurons are trained to find out modifications in the external and internal conditions so that a person's body can react to that change. A stimulus is the first signal that is recognized by any sensory receptor of the body. Stimulus is an impulse generated when there is a change in the surroundings of a person. For example, a heated environment will alert the brain through the thermal sensory organs and generate a reflex accordingly.
Sensory Receptors
The human sensory system is one of the most complex and highly evolved structures, which processes a myriad of incoming messages. This well-coordinated system helps an organism or individual to respond to external stimuli, appropriately. The sensory receptors are an important part of the sensory system. These receptors are specialized epidermal cells that respond to external environmental stimuli. These receptors consist of structural and support cells that form the peripheral unit of the receptor and the neural dendrites which receive and detect the external stimuli.
