Given what we know we can confirm that the tracheal wall is related to its function in that it allows it to conduct air in a sealed manner and protect the individual.
<h3>What is the function of the trachea?</h3>
The primary function of the trachea is to conduct air into the lungs. For this, the trachea is long and narrow, to allow air to flow in a directed manner towards the lungs. The trachea is also "armored" to protect this air flow and is lined with mucus to sweep away any unwanted particles from the air.
Therefore, we can confirm that the trachea is armored and lined with mucus along its long, tube-like shape, which allows this structure to conduct air in a safe, clean, and direct manner directly towards the lungs.

In natural experiments, the researcher compares groups exposed or not to exogenous agents, but does intervene in group composition or independent variable modification. This is a natural experiment.
<h3>
What is a natural experiment?</h3>
There are two types of investigation strategies,
- Manipulative investigation
In a natural experiment the researcher does not intervene in the creation of treatment and control groups.
There is an exogenous agent, such as a natural phenomenon, that influences the study groups and that acts as the treatment.
The researcher takes advantage of these events to use these random groups to compare them in the study.
The researcher chooses exposed groups (experimental groups) that might have been affected by the natural event and other groups that have not been affected (control groups).
In the exposed example,
- Exogenous agent ⇒ Treatment ⇒ pesticide use
- Exposed group ⇒ Experimental group ⇒ birds from nests in pesticide-sprayed fields
- Not exposed groups ⇒ Control groups ⇒ birds from nests in unsprayed fields.
Since the researcher does not voluntarily modify the independent variable to observe a response in the dependent variable, this experiment could not be considered to be manipulative.
This is an example of a natural experiment in which the researcher chooses groups exposed to different conditions to compare them and analyze the effect of the pesticide.

Geomagnetism is the study of the dynamics of the Earth's magnetic field, which is produced in the inner core. The Earth's magnetic field is predominantly a geo-axial dipole, with north and south magnetic poles located near the geographic poles that undergo periodic reversals and excursions.
Answer:
The correct answer is- It is used to produce glucose molecule
Explanation:
Photosynthesis is a process in which light energy is captured by chlorophyll which is then used to convert carbon dioxide and water into glucose. Oxygen is also produced as a by-product in this process.
The light energy is used to split water into oxygen, hydrogen ions and release electrons from it. The electrons pass through many electron carriers through photosystem II and I and ultimately reduce NADH+ to NADPH which is used in the Calvin cycle to produce glucose.
Therefore glucose is produced by the help of light energy captured during photosynthesis.
Scientific inquiry requires logical ideas that can be tested
