Answer:
Speciation is defined as an evolutionary process in which one population evolves into a distinct species.
Speciation in reverse, or despeciation is defined as the extinction of an old species due to combining with evolved species to produce hybrid species but it conserves biological lineage.
In the given research, the term used despeciation or speciation in reverse is appropriate as hybrid species resulted from interbreeding of Galapagos two finch species conserved the biological lineage but also loss one of the species Darwin discovered.
Answer:
The time between the end of ventricular systole to the beginning of atrial systole is 100 ms or 0.1 seconds.
Explanation:
Ventricular systole is the removal of blood from the heart by pumping through aorta and pulmonary vein. Both aorta and pulmonary vein receive the blood from the heart. Aorta receives oxygenated blood and pulmonary vein receive deoxygenated blood, while atrial systole is the addition of blood into the ventricular from vena cava and pulmonary artery due to contraction of heart. This process occurs in 100 ms.
Answer:
The third stage in the synthesis of fatty acids is the synthesis of palmitic acid (letter e)
Explanation:
The synthesis of fatty acids takes place in the cytoplasm of the cell. The first step is the transport of acetyl-CoA to the cytoplasm. This came in the form of citrate usually from the pyruvate generated in the glycolysis from the mitochondria. The citrate is enzymatically transformed into acetyl-CoA.
Once the acetyl-CoA is in the cytoplasm, this is transformed into malonyl-CoA. This molecule will be the donor of two carbons in the synthesis of fatty acids.
In the final step takes place a cyclic process of reactions (condensation, reduction, hydration and second reduction) to synthesize the palmitic acid ( 16 carbons) by the fatty acid synthase.
Answer:
A. Student A because it requires a hypothesis
Some of the important questions to be asked should be: Is the procedure of obtaining the results accurate? If not, by how much is its reliability? Are the results useful for further scientific research? What can you recommend to others who might want to make the same scientific conclusions?
