Andreyy89

Answer:

The most appropriate answer would be option B.

The flaw in their reasoning is that they compared different molecules in a different set of organisms.  

For example, they compared the DNA of lizard A and B whereas they compared the RNA of lizard B and C.

In addition, the mutation rates of different molecules (DNA and RNA) are different and thus, comparison of DNA in one set of organism and comparison of RNA in another set cannot be used as the basis for the conclusion.

Three physical forces are involved in glomerular filtration: glomerular capillary blood pressure, plasma-colloid osmotic pressur
Elodia [21]

Answer: a. True

Explanation:

Glomerular filtrate is formed by the difference in force of hydrostatic and osmotic pressure. This physical force involves:

Bowman's capsule hydrostatic pressure: This includes the pressure that develops in the Bowman's capsule against the fluid to be filtrated expelled out by the glomerulus.

Glomerular hydrostatic pressure: The glomerulus is the main site of production of filtrate. It is higher than the average blood capillary hydrostatic pressure. It allows the water and solute molecules to be filtrated out of the plasma membrane.

Colloid osmotic pressure: The osmotic pressure which is generated by the large molecules is the colloid osmotic pressure. It is created by the plasma proteins. This pressure draws water from the glomerulus.
