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.

Pure liquid water has pH of 7 which means that water is
just olya [345]

Answer: neutral

Explanation: The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

These two cells have several features in common. They also differ in several ways. The two cells share all but one feature liste
Kobotan [32]

Answer:

The correct answer would be B) enclosed in a protein capsule

Almost all living cells contain DNA as their genetic material. DNA control and coordinates the function of the cell. The two cells also must contain the DNA.

Cellular respiration refers to the set of biochemical reactions by which the cell generates ATP or energy. All the living cells produce energy through cellular respiration, however, they may utilize the aerobic or anaerobic form of respiration.

A ribosome is found in all the living cells including animal cells, plants, bacteria et cetera. They form the site for protein synthesis in all the cells.

The protein capsule is not a universal feature of all living cells. Thus, it may be present in one cell type and absent in another cell type.

If both parents contribute identical versions of a gene, then the offspring are ______ for that gene.
elena-14-01-66 [18.8K]

Homozygous is the condition that the offsprings would have, if both their parents contribute identical versions of a gene.

<h3>What is the difference between homozygous and heterozygous ?</h3>
  • Homozygous and heterozygous are terms that are used to describe allele pairs.
  • Individuals carrying two identical alleles (RR or rr) are known as homozygous.
  • Individual organisms bearing different alleles (Rr) are known as heterozygous.
  • Homozygous produce only one type of gamete whereas heterozygous produce two types of gametes.
