23. Each of the following reading comprehension questions are based on the content of the following passage. Read the passage and then determine best answer choice for each question. Base your choice on what this passage states directly or implies, not on any information you may have gained.

Both plants and animals of many sorts show remarkable changes in form , structure, growth habits, and even mode of reproduction in becoming adapted to different climatic environment,types of food supply , or mode of living. This divergence in response to evolution is commonly expressed by altering the form and function of some part or parts of the organism, the original identity of which is clearly discernible. For example, the creeping foot of the snail is seen in related marine pteropods to be modified into a flapping organ useful for swimming ,and is changed into prehensile arms that bear suctorial disks in the squids and other cephalopods.The limbs of various mammals are modified according to several different modes of life- for swift running (cursorial) as in the horse and antelope, for swinging in tress(arboreal) as in the moles and gophers, for flying(volant)as in the bats, for swimming( aquatic) as in the seas, whales, and dolphins, and for other adaptions. The structures or organs that show main change in connection with this adaptive divergence are commonly identified readily as homologous, in spite of great alterations. Thus, the fingers and wristbones of a bat and whale, for instance , have virtually nothing in common except that they are definitely equivalent elements of the mammalian limb.

Adaptive Divergence (Answer)

Evolution

Unusual Structures

Change in Organs
