Answer:
Sucrose passes through your mouth and stomach virtually undigested. Once it enters the initial part of your small intestine, an enzyme called sucrase is secreted from the mucosal membrane. Sucrase breaks down sucrose by cleaving it in half, which produces one molecule of glucose and one molecule of fructose. The glucose is immediately absorbed into the bloodstream and transported around the body. In contrast, fructose is also absorbed in the small intestine, but it’s shuttled to the liver where it spends more time either being reduced into glucose, stored as glycogen or converted into lipids. In addition to sucrase, another enzyme called isomaltose glycoside hydrolase can also help facilitate the breakdown of sucrose. Overall, sucrose is readily assimilated and produces a quick boost of energy -- about 3.94 kilocalories of energy per gram.
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
Answer:
The correct answer is option C. Epstein-Barr virus: virus visible inside red blood cells.
Explanation:
The Epstein-Barr virus is a virus or virions that cause several serious diseases such as Guillain-Barre syndrome and kind of cancers. These viruses can be detected by the making smear of blood in the electron microscope.
The electron microscope shows round capsids that have protein encased genetically material that is loosely enclosed in a membrane. These are transmitted through saliva generally.
Thus, the correct answer is C.
Answer:
186
Explanation:
The Polymerase Chain Reaction (PCR) is a technique used in molecular biology to amplify small segments of DNA. This technique uses a pair of oligonucleotide sequences called 'primers' which bind to opposite strands of the heat-denatured DNA template in order to amplify this target DNA sequence. In this case, the DNA template is composed of a single unit of 130 base pairs (bp) and four repetitive units of 14 bp, so the final PCR product will have 186 bp >>> 130 bp + (14 bp x 4) = 130 + 56 = 186.
