Answer:
Polypeptides are composed of amino acids, and we know amino acids are differently charged, have different R groups, and also have different isoelectric points. Depending on different isoelectric points and charged groups, the polypeptides can be separated and because a protein has its lowest solubility on its isoelectric point.
So in this question,
(a) (Lys-Ala)3 ; this is highly positively charged (polar) at pH 7 than (Gly)20 which is uncharged except for the amino and carboxyl terminal.
(b) (Glu)20 ; it is highly negatively charged at pH 7 whereas (Phe-Met)3 is much less polar and hence less soluble.
(c) (Asn-Ser-His)5 ; at pH 3, because in (Ala-Asp-Gly)5 the carboxylate groups of Asp residues are partially protonated and neutral, whereas in (Asn-Ser-His)5 , the imidazole groups of His residues are fully protonated and positively charged.
(d) (Asn-Ser-His)5; at pH 6.0; both polymers have polar Ser sidechains, but (Asn-Ser-His)5 also has the polar Asn side chains and partially protonated His side chains.

The answer is B
Explanation:
Think of it this way; Respiration = Breathing and we are on the cellular level
When using high power the diameter of the field of view would be 20 mm.
A microscope is an optical device that is used to view images that cant be seen with the naked human eyes.
It is made up of lens in which the diameter field of view can be determined.
The diameter of the viewed field in an optical microscope is termed the field number and represents the diameter of the field measured in millimeters (mm) at the intermediate image plane.
From the question, there are two types of field of view
- <u>Low-power field of view</u>: which is 2 millieters(mm) and
- <u>High power field of view</u>: which is 10 × low-power field of view
Therefore, to determine the diameter of the field of view when using high power is
10 × 2 = 20mm

The correct answer is D. none of the above.
All of the above answers are examples of energy transformations. Plants get their energy from the sun through photosynthesis; when herbivores feed on those plants, they receive energy from the plants, and when predators feed on the herbivores, the predators get their energy from their prey.
Hope this helps! :)
