Fossils can be classified by their morphology (how they look), ethologically (how they acted), and toponomically (where they are in the substrate layers) to produce phylogenetic trees. However, more recent advances in genetic technology allow us to extract DNA from more recent fossils that have not had too much breakdown of the DNA, and we can much more accurately classify species from that information, and also provide much more accurate phylogenetic analysis.
Answer:
the difference is:
Plant cells have a cell wall, large central vacuole, and chloroplasts, while animal cells do not.

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.
