Answer:
F stands for feather R stands for red and W stands for white.
Explanation:
The answer for the above question is Mutation.
Mutations are random spontaneous changes that occur suddenly in the DNA. A single mutation can have a large effect, however in may cases evolutionary changes are based on the accumulation of many mutations. The gene flow is any movement of genes from one generation to another and is an important source of mutation
Carbonized remains are thin, approximately two-dimensional films of carbon preserved on a flat surface of rock. They are most often black in color, reflecting the fact that they composed mostly of carbon (as is coal, which is also black in color). Most fossils that exhibit “soft part” preservation are carbonizations.
I would say the answer is the Carbon remains of the original organism.
The pressure inside your lungs and the pressure outside them fluctuate as you breathe. An illustration of a pressure gradient is this.
<h3>What is an example of pressure gradient?</h3>
- The pressure gradient is the amount by which the atmospheric pressure drops in a location at a particular time.
- A pressure gradient is demonstrated by gale-force winds in one city changing to a moderate breeze after an hour. the rate of the pressure in space decreasing (gradient) at a specific period.
<h3>How does pulmonary ventilation change with pressure gradient?</h3>
Thoracic ventilation Because air moves down a pressure gradient, or from an area of greater pressure to an area of lower pressure, the difference in pressures is what drives pulmonary ventilation.
When breathing in and out, the respiratory airways restrict the flow of air. The air must be transported by the pressure gradient from the mount (or nose) to the pulmonary alveoli.
