Cells differentiate because they need to become specialized. which is an not example below of how specialized cells have unique structure and function nerve cells have dendrites and axons, giving them a “pathway-like” shape which can be used to send and receive signals. bacteria cells are small in size in order to easily diffuse in and out of the cytoplasm. muscle tissue is shaped differently than skin tissue because muscle cells have to expand and contract. eyes are composed of rod and cone cells which change shape to allow light to move in and out of cells.

Joe is breeding cockroaches in his dorm room. he finds that the average wing length in his population of cockroaches is 4 cm. he chooses the six cockroaches that have the largest wings; the average wing length among these selected cockroaches is 10 cm. joe interbreeds these selected cockroaches. from earlier studies, he knows that the narrow-sense heritability for wing length in his population of cockroaches is 0.6. a. calculate the selection differential and expected response to selection for wing length in these cockroaches. b. what should be the average wing length of the progeny of the selected cockroaches?
