The statement that describes a method by which the body prevents airborne pathogens from entering the lungs during respiration is as follows: the mucus in the nose traps microscopic particles and bacteria while nose hairs filter out larger particles.
<h3>What is the role of the lungs?</h3>
The lungs are biological organs of vertebrates that controls breathing and oxygenates the blood.
The lungs is the major breathing organ of the body and is connected to the nose through a pipe called trachea and bronchi.
However, to prevent unwanted or foreign particles in the atmosphere from entering into the lungs, the mucus in the nose helps trap the microscopic particles while the hairs in the nose blocks the passage of larger particles.

Photosynthesis is a series of metabolic reactions by which plants synthesize biomolecules by using sunlight. During this process, plants use simple molecules (H2O, CO2) to create oxygen and chemical energy.
- During photosynthesis, chemical energy is stored in the chemical bonds of simple carbohydrates (e.g., glucose).
- The statement above IS NOT TRUE because plants need to sequester nitrogen from the soil to build amino acids.
- Carbohydrates are biomolecules consisting of Hydrogen, Carbon, and Oxygen.
- Plants require Nitrogen, Phosphorous and Sulfur from the soil in order to to create different biomolecules such as proteins (whose building blocks are amino acids) and nucleic acids.

Answer:
Lava from a volcanic eruption hardens into bare rock. Primary succession begins with soil formation. The first stage of succession involves pioneer species. In primary succession, pioneer plants are those that can grow without soil, such as lichens.
