Answer:
Airways diameter can influence the airflow resistance.
Explanation:
Airflow resistance follows the same principle followed by the airway resistance. This is the resistance offered during the pulmonary blood flow.
Airways diameter affects the airflow resistance. If the diameter of airway is increased, the airflow resistance decreases and air can flow easily in the body. The decrease in the airway diameter (dilution) increases the airflow resistance of the blood artery.
The synthesis of fatty acids starts with a preparatory step in which acetyl-CoA is mediated from mitochondria to the cytosol. However, it cannot pass through the membrane, so it is transported as citrate, which is cleaved to acetyl CoA and oxaloacetate.
In the cytosol, acetyl CoA is transformed to malonyl CoA, that is, a three carbon compound. Fatty acid synthesis starts with the conduction of acetyl group from acetyl CoA to fatty acid synthase.
Two carbon groups, supplied to malonyl CoA, are supplemented to the developing acyl chain in a series of steps involving condensation, reduction, and dehydration reactions. Elongation of the fatty acid chain ceases at 16 carbon atoms, after seven cycles, as the free free fatty acid is discharged.

Recombination
: the process occurring in Meiosis I, in which offspring are able to obtain unique traits resulting in an array of different phenotypes (physical appearances).
Prophase I,
the homologous chromosomes line up in the middle of the cell and exchange segments of alleles, and then lining up in the cell in a NON-uniform way.... therefore resulting in genetically unique offsprings rather than identitical.
Mutations are result of evolutionary factors. They create genetic diversity that helps species adjust to different climates, behaviours and foods. Mutations that occur in a fit indivual can result in offspring that are genetically more successful in adjustments to different climates, foods, and environments.
All in all Recombination results in unique looking indivuals, whereas mutations result in greater survival chances of a species.
