Lobe-finned fishes are characterized by lobes in their fins in addition to the basic characteristics of fishes.
<h3>What are lobe-finned fishes?</h3>
Lobe-finned fishes are a group of fish known as Sarcopterygii. They possess the basic characteristics of fishes such as swim bladder, lateral lines, etc.
They are a sister group of ray-finned fishes. In addition, lobe-finned fishes possess the following characteristics:

Answer:
Electrons Can Donate - 0
Electrons Can Receive- 2
Valence  - 2
Explanation:
The electronic configuration of oxygen is  . Thus in the p-orbital there is deficiency of two electrons. Hence, it can receive/share electron but it cannot donate electrons. This makes oxygen as a good electron acceptor. Since there is a deficiency of two electrons in the outermost shell of oxygen, the valence of oxygen in thus -2

Answer:
what is the role of atp in the sodium potassium pump?
Adenosine triphosphate plays vital role in sodium potassium pump as energy is required to complete the process with the aid of ATPase which is an enzyme that hasten or catalyzes the process.
