Answer:
After transcription, some RNA molecules are altered to contain bases not encoded in the genome. Most often this involves the editing or modification of one base to another, but in some organisms can involve the insertion or deletion of a base. Such editing events alter the coding properties of mRNA.

Answer:
The process of photosynthesis and cellular respiration are really all about metabolism that deals with the synthesis of various bioactive molecules required by the body.
Explanation:
Now in case of photosynthesis CO2 is absorbed from the atmosphere which reacts with water to generate glucose(C6H12O6) and oxygen(O2).
6CO2+12H2O=C6H12O6+6O2+6H2O
On the other hand during aerobic respiration glucose molecule is oxidized in 3 stages Glycolysis,TCA cycle and Oxidative phosphorylation to generate CO2,H2O and energy in form of ATP molecules.
C6H12O6+6O2=6CO2+6H2O+38ATP
Answer:
W - Facilitates movement of air by expansion and contraction, X - Traps dust and helps to filter inhaled air, Y - Prevents the wind pipe from collapsing, Z - Help in exchange of gases.
Explanation:
Diaphragm is the muscle that separates the thoracic cavity from the abdomen. The diaphragm is the main muscle of respiration. Contraction of the diaphragm muscle expands the lungs during inspiration when breathing air in. The function of the nasal cavity is to warm, moisturize, and filter air entering the body before it reaches the lungs. Hairs and mucus lining the nasal cavity help to trap dust, mold, pollen and other environmental contaminants before they can reach the inner portions of the body. The trachea, or windpipe, is a 5-inch long tube made of C-shaped hyaline cartilage rings lined with pseudostratified ciliated columnar epithelium. The trachea connects the larynx to the bronchi and allows air to pass through the neck and into the thorax. The rings of cartilage making up the trachea allow it to remain open to air at all times. Gas exchange of oxygen and carbon dioxide takes place in the alveoli. Oxygen from the inhaled air diffuses through the walls of the alveoli and adjacent capillaries into the red blood cells. The oxygen is then carried by the blood to the body tissues.
