The four important characteristics of respiratory surface are:
1. Thin walls
2. Moisture
3. Large surface area
4. Blood supply
Respiratory system or respiratory tract is divided into upper and lower tract. Upper respiratory tract includes nose and its cavities, sinuses, pharynx and the part of the larynx. Lower respiratory tract consists of the trachea, bronchi, bronchioles and the alveoli.
Alveoli are the ends of the respiratory tract the smallest units in it. Alveoli are small folded air sacs that are branching off from alveolar ducts and providing an extremely large surface area for the gas exchange. Gas exchange occurs thanks to small blood vessels – capillaries that surround alveoli and it occurs via the process of diffusion.
So, respiratory surface is thin membrane also known as the blood–air barrier that consists of the alveolar epithelial cells, their basement membranes and the endothelial cells of the alveolar capillaries.
Explanation:
A correct father is identified through the current techniques for paternity testing are using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP).
A suspect is identified using a small sample of evidence forensic DNA analysis
Forensic DNA analysis usually involves comparisons between genetic profiles extracted from biological samples collected from a specific site, object or person which is thought to be associated to a crime, in order to determine the likelihood that such samples come from a particular person
A missing person is correctly identified by

Prophage occurs when it detaches from carbohydrates to create a virus. The correct option among all the options that are given in the question is the third option or the penultimate option or option "C". I hope that this is the answer that has actually come to your desired help.
The transformer is a static electric machine (because it contains no moving parts) belonging to the broader category of converters. In particular the transformer to convert the parameters of voltage (V symbol unit [V] volts) and current (symbols The unit [A] amperes) input than output, while maintaining constant the amount of power electrical (less the losses due to hysteresis and eddy currents). The transformer is a machine able to operate only in alternating current, because it exploits the principles of electromagnetism linked to variable flows. <span>The transformer has paramount importance in today's world: without it, the electricity transmission grids that connect power plants to millions of homes and industries could not function</span>
