Answer:
c. DNA
Explanation:
The DNA is double stranded molecule that twist around each other to form a double helix structure. Each strand consists of nucleotide bases joined together by deoxyribose sugar-phosphate backbone.
<em>The two strands of the DNA lies anti-parallel to each other and each strand has two ends - the 5' end where the phosphate group gets attached to the 5′ carbon of a ribose sugar and the 3' end where there is a free hydroxyl group attached to the 3′ carbon of a ribose sugar.</em>
Hence, the correct option is c.
Answer: Option A.
Explanation:
Maltoporin is a membrane protein. It forms trimetric structure that facilitate the translocation of maltodextrins across outer membrane of E.coli bacteria. It is responsible for the guided diffusion in E.coli. it recognised bacteriophage sequence. It formed water filled pores across the outer membranes of gram negative bacteria. The lining of channel with maltoporin has a series of aromatic side chains stranded in a helical pattern matching the relative curvature of the protein backbone, thus providing little restriction to transport.

Answer:
B
Explanation:
Wall cell has to be strong to bring protection to the cell. In general it is made of beta-glycosidic bonds.
Storage polysaccharides, are a source of available energy for the cell in any moment. Therefore, the bonds of storage polysaccharides need to be weak. In that way, when the cell needs energy from carbohydrates, it is not going to spend so much energy trying to break the bond.
Based on the scientific method, for the scientist using radioactive dating to determine the age of a fossil, the best way to increase reliability is by doing repeated analyses of the fossil finding it to be the same age each time.
<h3>What is the best way to increase reliability of a discovery?</h3>
In science, the reliability of findings can be increased by taking repeated measurements.
In the case of the scientist using radioactive dating to determine the age of a fossil, the best way to increase reliability is by doing repeated analyses of the fossil finding it to be the same age each time.
