Anatomical homology in vertebrate forelimbs is considered to be evidence for evolution because: 1. differences among vertebrate
Finger [1]

Answer :3. similarities among vertebrate forelimbs suggest that they evolved from a common ancestor.

Explanation:

The study of differences and similarities in the anatomy of different species is comparative anatomy. It is based on the concept that  

1.)Homologous structures  which are present in different species, because they have a common decent and must have evolved  divergently from a shared ancestor. Theses anatomic structures may not be used for the same purposes. For example the forelimb of fox and whale.

2. Some  structures (Analogous)which are similar in different organisms must have evolved  ,(acquired through natural selection) through convergent evolution in similar environment,  and not inherited from a recent ancestor. These organisms usually use these structures for a common purpose. For example the streamline body shape   of shark and porpoises, which though are used for a common purpose of swimming, were inherited from different ancestors.

.  Example  of comparative anatomy is the common  bone structures in forelimbs of fox, whales, bats, and humans. These appendages is made up of  the same basic parts; despite serving  different functions.  

Comparative anatomy helps scientists in classification of organisms based on their similar characteristics of their anatomical structures.

What are the 3 substances which are reabsorbed from the nephron in the blood?
Setler [38]

The main substance re-absorbed into the blood in the nephron are glucose, electrolytes (sodium, potassium, chloride)  and water.

Almost all the glucose is reabsorbed at the proximal tubule of the nephron. Sodium, potassium and chloride are reabsorbed  at the ascending loop of  Henle, and water is reabsorbed at the descending loop of Henle.

Other nutrients that are reabsorbed are  magnesium, phosphates, carboxylate, bicarbonate, amino acids, some urea, proteins and oligopeptides.

Reabsorption occurs in two steps namely active or passive extraction of sustances  from the fluid  in the tubules of the nephron, and into the interstitium , then transport of these substances from interstitium and into the bloodstream.
