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.
Microorganisms that are capable of causing disease are called pathogens. Although microorganisms that cause disease often receive the most attention, it is important to note that most microorganisms do not cause disease. In fact, many probably provide some protection against harmful microorganisms because they effectively compete with the harmful organisms for resources, preventing them from growing.

Answer:
B. Arm length
C. Shape
D. Centromere placement
Explanation:
Cytogenetics is a discipline that study the structure and number of chromosomes including their morphology, position of the centromere, arm length, staining bands, etc. These features can be observed by microscope and enable us to identify different genome rearrangements (i.e., translocations, deletions, centric fusion, chromosome duplications, etc.) by ilustrating chromosomes in defined pictures referred to as karyotypes. In consequence, they are chromosome features that can be used in order to categorize different samples.
