How Could the "Demographic History of Neanderthal Populations" Be Explored

question 30

Multiple Choice

How could the "demographic history of Neanderthal populations" be explored if mitochondrial DNA from other Neanderthal samples could be PCR amplified?

• A)These Neanderthal sequences could be compared to those of modern humans to learn if they are closely related.
• B)These Neanderthal sequences could be compared to those of modern humans;the more they differ,the more distant the time of divergence between the Neanderthal and modern human lineages.
• C)These Neanderthal sequences could be compared to each other to see how much they differ;the more they differ,the greater the divergence between these populations.
• D)In the attempt to amplify other Neanderthal DNAs,those that amplify must be from more modern populations and those that don't are from more ancient populations.

Bowman Capsule

The Bowman capsule encases the glomerulus in the kidneys, where filtration of blood begins in the process of urine formation.

Filtration Slits

Narrow gaps between the podocytes in the kidneys that allow for the filtration of blood, serving a crucial role in the formation of urine.

Podocyte Processes

Extensions of podocytes, cells in the kidney that wrap around capillaries of the glomerulus, playing a key role in the filtration of blood.

Juxtaglomerular Apparatus

A specialized structure in the kidney that regulates blood pressure and the filtration rate of the glomerulus.
