Ques: Answer the following question given this paragraph: Both amylopectin and glycogen contain branch points that are linked through -1,6linkages. These branch points occur more often in glycogen. Dextrins are glucose polysaccharides of intermediate size. The shine and stiffness imparted to clothing by starch are due to the presence of dextrins formed when clothing is ironed. Because of their characteristic stickiness with wetting, dextrins are used as adhesives on stamps, envelopes, and labels; as binders to hold pills and tablets together; and as pastes. Dextrins are more easily digested than starch and are therefore used extensively in the commercial preparation of infant foods. The complete hydrolysis of starch yields, in successive stages, glucose:. Q: The complete hydrolysis of starch yields what? Choices: - glutamate - insulin - sucrose - glucose A:
Ans: glucose

Answer the following question given this paragraph: Natural selection occurs when there are differences in fitness among members of a population. Q: Differences in fitness among different members of a population can lead to what kind of selection? Choices: - fluid selection - subliminal selection - origin selection - natural selection A:
(A).
natural selection
Ques:Answer the following question given this paragraph: The dipeptide has a free amino group on one end of the molecule and a free carboxyl group on the other end. Each is capable of extending the chain through the formation of another peptide bond. The particular sequence of amino acids in a longer chain is called an amino acid sequence. By convention, the amino acid sequence is listed in the order such that the free amino group is on the left end of the molecule and the free carboxyl group is on the right end of the molecule. For example, suppose that a sequence of the amino acids glycine, tryptophan, and alanine is formed with the free amino group as part of the glycine and the free carboxyl group as part of the alanine. The amino acid sequence can be easily written using the abbreviations as Gly-Trp-Ala. This is a different sequence from Ala-Trp-Gly because the free amino and carboxyl groups would be on different amino acids in that case. Q: What is the particular sequence of amino acids in a longer chain called? Choices: - atomic sequence - molecular sequence - carbon sequence - amino acid sequence A:

Ans:amino acid sequence
Ques:Answer the following question given this paragraph: Kirchhoff's Second Rule Kirchhoff's second rule (the loop rule) is an application of conservation of energy. The loop rule is stated in terms of potential, V , rather than potential energy, but the two are related since PE elec = qV . Recall that emf is the potential difference of a source when no current is flowing. In a closed loop, whatever energy is supplied by emf must be transferred into other forms by devices in the loop, since there are no other ways in which energy can be transferred into or out of the circuit. Figure 21.23 illustrates the changes in potential in a simple series circuit loop. Kirchhoff's second rule requires emf equals the sum of the. Q: Kirchhoff's second rule (the loop rule) is an application of conservation of what? Choices: - heating - Rock - mineral - energy A:

Ans:
energy
