Nitrogen is released to the abiotic parts of the biosphere from the process death and by bacteria.
DNA contains instructions for making the different molecules that a cell needs to grow and function. For example, proteins are made by translating mRNA.
<h3>What is DNA and what is its function?</h3>
DNA is the structure responsible for transmitting all genetic characteristics — such as eye, skin and hair color, physiognomy, among others — in the process of reproduction of living beings. In this way, the main function of DNA is to carry information contained in its sequences, called genes.
DNA is made up of two chains of polynucleotides (strand), which are made up of several nucleotides. Nucleotides are joined together by bonds called phosphodiester (phosphate group linking two sugars of two nucleotides).

Answer: The question is not complete, here is the completed part gotten from other website.
Mammals and turtles are more closely related than are lungfishes and sharks. Hagfishes, lungfishes, and frogs have lobed fins.
Lancelets and coelacanths are more closely related than are chimaeras and coelacanths.
Organism (a) is a common ancestor of all chordates.
Descendants of organism (d) have limbs with digits. birds and ray-finned fishes have a notochord and jaws.
rays and frogs have vertebrae. organism (c) is a common ancestor of lampreys and lungfishes?
The correct options are;
Mammals and turtles are more closely related than are lungfishes and sharks.
Descendants of organism (d) have legs.
Rays and frogs have a vertebral column.
-Birds and ray-finned fishes have a notochord and jaws
Explanation:
This is because phylogenetic tree is a branching diagram that entails different evolutionary relationships that occur between organisms or biological species having common decent or ancestors and showing similar and differences in their genetic characteristics or traits. It shows how species evolved from their ancestors.
