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.
<span>If the energy in glucose was released at once, most of the energy would be lost as light and heat. The light and heat could harm or even destroy the cell. The gradual process of cellular respiration allows the cell to control the release of energy into packages of ATP that can be used efficiently for cell activities.</span>
Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. Out in the depths of the ocean, tsunami waves do not dramatically increase in height. But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases.
