How does the adaptation help the animal survive and reproduce?<br> Giraffe
GarryVolchara [31]
(A)An adaptation is a characteristic that helps an animal survive in its habitat. All animals must be able to obtain food and water, protect themselves from harm, withstand the climate, and reproduce young so the species doesn't become extinct. ... Without their adaptations, the species could not thrive in that environment.
GIRAFFE-That ability – coupled with the tongue's impressive reach and its tough skin – allows giraffes to selectively browse, plucking leaves from among the nasty thorns brandished by many of its preferred food trees, such as acacias.

One method for separating polypeptides makes use of their different solubilities. The solubility of large polypeptides in water
Naddika [18.5K]

Answer:

The solubility of any substance in water depends on its polarity. The polar molecule dissolves more easily in the water than the non polar molecule. Amino acids have different polarity at different pH.

(a) (Lys-Ala)3 : The (Lys-Ala)3 contain more positive charge and highly polar the at pH 7 as compared with the  (Gly)20 that remains uncharged and has less polarity.

(b) (Glu)20 :This amino acids negatively charged at pH 7 and highly polar than the (Phe-Met)3 which is non polar or less polar and hence least soluble  in water.

(c) (Asn-Ser-His)5 is highly polar at pH 3 as compared with the (Ala-Asp-Gly)5 that contains the carboxylate groups of Asp residues that are partially neutral. The  (Asn-Ser-His)5 contains = the imidazole groups of His residues are fully polar and soluble in water.

(d) (Asn-Ser-His)5 is polar at pH 6.0 because both have polar side chains Ser but (Asn-Ser-His)5 is only partially partially protonated due to the His side chains. Thus,  (Asn-Ser-His)5 is more soluble in water.
