Two important factors is temperature and liquid water.
Answer:
the olfactory epithelium
Explanation:
There are several protective features of the respiratory system which is responsible for stopping the less aggressive pathogens. Some of these protective features are:
Hairs in nose which trap pathogens like bacteria, virus from entering the lungs. The respiratory tract has mucus which is responsible for trapping the microbes and mucus have IgA antibodies which helps in eliminating these microbes. Alveolar macrophages engulf the pathogen and digest them
Olfactory is not a protective feature of the respiratory system and is responsible and adapted to detect the odor and transfer this signal to the brain.
Based on the question above, the best answer would be:
Interphase
Prophase - condensed
of chromosomes
Metaphase – the cells are lined up at the spindle for its
preparation to be divided
Anaphase – in this part, the chromatids are separated from
each other, and pulled to the opposite ends
Telophase – This is where the cells are nearly done
diving for the cell contents to take
place.
Cytokinesis – Two new cells are formed
