Document Summary
Ex: large variation in egg size & number. Induced production of small eggs by removing yolk. Clutches with small # of eggs, removed all but a couple eggs. Control: sham operations of exposing eggs but left eggs alone. Adaptation: genetic change in population due to natural selection from environment. Acclimatization = phenotypic change in individuals response to short-term environmental changes. 41. 2 tissues, organs & systems: how structure correlates with function. Protein shape and enzyme role, structural component, transporter. Secrete hormones/ digestive enzymes have rer and golgi to store energy and fat droplets. Tissues: groups of similar cells that function as a unit. Developing embryonic tissue rise to 4 adult tissue types: Each connective tissue secretes distinct type of extracellular matrix, depending on nature. Soft matrix, packing b/w organs & padding under skin. Adipose tissue - cells dominated by fat droplets. Tendons & ligaments connecting muscles, bones & organs. Transplant ligaments, low chance of rejection b/c no blood flow c)
