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.

Answer:
The conversion is needed to regenerate the molecules needed for glycolysis
Explanation:
Fermentation is a metabolic process by which microorganisms generate ATP by the anaerobic (without oxygen) degradation of organic nutrients. Fermentation allows to microorganisms convert carbohydrates into alcohol or acid. During glycolysis, two NAD+ molecules are reduced and glucose molecules are split into two pyruvate molecules, thereby producing two NADH molecules and two ATP molecules. During fermentation, pyruvate molecules are metabolized to different compounds because the energy stored in the pyruvate molecules is unavailable to the cell. In fermentation, NADH from glycolysis is oxidized back to NAD+ by being used to reduce pyruvate or a pyruvate derivative.
Answer:
The key to the adaptation of living beings on the planet is the adaptation to abiotic factors such as temperature, light, salinity, humidity; and to biotic factors, which are represented by the action of the other organisms.
Explanation:
Answer:
Option A
Explanation:
Options
A. most populations were fixed for a single genotype, but genotypes varied among populations
B. average heterozygosity was declining steadily over time
C. individual populations were polymorphic for several loci and most populations were genetically similar to one another
D. all populations were fixed for the same allele at each locus studied
Solution
As per the study conducted by Templeton, it was found that human affect the biodiversity at all biological levels such as genetic, ecosystem, species etc. and behind genetic variation two important factors are genetic drift and gene flow.
Both the gene flow and genetic drift produce opposite results as genetic drift increase variation with in the species but decrease variation with in the local population and the opposite of this happens in gene flow.
Genetic drift has actually lead to speciation of collared lizards among themselves for a specific genotype
Hence, option A is correct
