Answer:
Cartilage rings of trachea have protective role
Explanation:
Trachea is a tube, part of the respiratory system, which allows the passage of the air: from larynx to lungs (primary bronchi). It is enveloped with cartilage rings that prevent collapse of the trachea when there is no air. The cartilage "rings" are C-shaped, except one full ring-shaped - the cricoid cartilage which attaches trachea to the larynx.

[b] The sporangia are knob-like structures.
They are present at the top of the thread-like structures called hyphae.
They are dispersive, i.e. they are scattered by rain, wind or insects.
The inaccurate reporting of an experiment data will lead to the following consequences:
- Data will lack quantitative measures.
- Data will be less reliable due to inaccuracy.
- Data will not be reproducible by other scientists for validation of test results.
- Data will weaken the proposed testable hypothesis of the scientist.
- Data will break any trend that has been previously observed by the scientist.
