Coelacanths and lungfish are collectively known as the lobe-finned fishes, and have fins containing similar arrangements of bone

s to those seen in tetrapod limbs. Which of the following statements about this relationship is TRUE?
O Because the fins of the lobe-finned fishes and the limbs of tetrapods are used for different purposes, they can not be homologous.
O Coelacanths and lungfish are considered to be the first tetrapods.
O This relationship is an example of a morphological similarity reflecting a likely evolutionary link.
O Despite the similar morphology of lobe fins and tetrapod limbs, genetic evidence suggests that coelacanths and lungfish are only distantly related to the tetrapods.

Answer:This relationship is an example of a morphological similarity reflecting a likely evolutionary link

Explanation:

Lungfish and Coelacanths are distinct from other fish because they are lobe-finned species.

Lately, major palaeontological studies proposed that Lungfish and Coelacanth form a  monophyletic sister group that is related closely to the tetrapods.

A monophyletic group is a group of organisms that include all the descendants and they share a common ancestor.

How do structures in living organisms compare with structures of nonliving things such as construction cranes, buildings, ships,
hjlf
For the answer to the question above, there is no such thing as a non-living organism. Because organisms are only a term for living things.

1. Cellular structure: all living organisms generally have a cellular structure i.e., they are made up of one or more cells. 
<span>The protoplasm is the physical basis of life. </span>

<span>There is no such fundamental and structural unit called cell in non-living things. </span>

<span>2. metabolism : The various life processes taking place within the body of an organism is collectively termed metabolism. The metabolic processes can occur only in living organisms and not in nonliving things. </span>

<span>3. growth, repair and death : Growth consists of the living organism absorbing materials entirely different from those that make up its body and convert them into body building substances. Growth in non-living substances such as crystal is at the cost of material similar to that of which it consists. Same substance is added without conversion. </span>
<span>The growth is permanent, irreversible process in living organisms but can be reversed in non-living things. </span>
<span>Growth is different in different parts of the body of an organism. Growth is uniform throughout in the non-living things. </span>

<span>Respiration, nutrition,excretion, movement,irritability, reproduction, life span, death, evolvability are other properties of a living organism.</span>
