Approximately 60% of human genes are also found in fruit flies. About 97.5% of human genes are also found in mice. What does thi

cestrela7 [59]

The presence of the 60 percent of similar genes in the fruit flies and humans, and 97.5 % similar genes in humans and mice suggests that the common ancestory of the humans and mice is much more recent than the common ancestory of humans and fruit flies. The majority of the similar genes in the mice and humans is the indication that they have evolved from a common ancestor not very long ago. However, only 60% similarity between fruit flies and humans indicates that it had been some time since they both have had a common ancestor.

Hence, the correct answer is 'Option D'.

Wittaler [7]

Answer: 1- Maintenance of oncotic pressure: prot. are macromolecules that hydrate in the plasma and exert a PO retaining water in the vascular medium, all prot. mainly albumin

2- Buffer role: all prot. Plasma acts as a buffer because of their hydrophobic character thus participating in the regulation of acid-base balance

3- Transport function Albumin.Tyroxine binding protein (TBP), transferrin, apoproteins..etc.

4- Enzymes and coenzymes: renin, orosomucoid (coenzymes of LPL)

5- Role in coagulation and fibrinolysis: fibrinogen, thrombin. antithrombin

6- Role in immunity: Ig (lgA JgG.lgM) and complement proteins

7- Role in the allergic: IgE and complement fractions

8- Role in inflammation: α1 antitrypsin, orosomucoides .cerulioplasmin, cytokines, CRP

9- Hormonal role: insulin, glucagon, pituitary stimulins (TSH, FSH, LH)

10- And finally a structural role (such as actin or tubulin that participate in the architecture of the cell, the keratin that makes
