Correct answer: D) From bacteria living in their roots
Nitrogen is an essential plant nutrients, but it is metabolically unavailable to higher plants and animals. It is available to some species of microorganism by biological nitrogen fixation in which nitrogen is converted to ammonia with the help of enzyme dinitrogenase.
The process of breaking apart the two atoms in a nitrogen molecule is called nitrogen fixation. Plant obtain the nitrogen they need from the soil which is already fixed by the bacteria and archae.
Example: <em>Azobacter</em><em>,</em> Nostac
I think one must rotate the pt into a supine position and protect her spine.
Supine position means lying horizontally with the face and torso facing up, as opposed to the prone position, in which is face down. When used in surgical procedures, it allows access to the peritoneal, thoracic and pericardial regions; as well as the head, neck and extremities.
The answer is: An organism is born with an adaptation. Therefore, the answer is an organism is born with it (B).
The correct answer is c) DNA.
The instructions for making proteins come originally from DNA. DNA is a macromolecule made of polynucleotide. Each nucleotide made of a phosphate, deoxyribose sugar and one of the four nitrogenous bases. The nitrogenous bases are adenine (A), guanine (G), cytosine (C) and thymine (T). The sequence of three bases in the DNA called codon. Each codon of the DNA codes for a particular amino acid for the synthesis of protein. Protein synthesis begins with the copying of the genetic information from DNA into a messenger RNA (mRNA) then mRNA is arrange amino acid sequence into a protein molecule.
