Answer:
Transpiration is the process of water movement through a plant and it’s evaporation from aerial parts, such as leaves, storms and flowers. Water is necessary for plants but only a small amount of water taken up by roots is used for growth and metabolis.
Water loss is a problem that occurs.
Explanation:
While an open stoma is neccesary for the plant to undergo photosynthesis, it comes with a negative side effect: water loss. Over 95% of a plant’s water loss occurs through the storm via water vapor.
Areolar tissues are loose tissues that usually adhere to epithelia. Areolar tissues contain blood vessels(we know epithelial tissues don't have blood vessels). Their main role is to procure food for epithelial tissues.
Answer:
The answer is D) Another biopsy from a distinct site may show a different result.
Explanation:
In molecular biology southern blot is used to detect a specific sequence of DNA. Mitochondria are energy producing organelles in the cell and they possess DNA that is inherited only from the mother. Although Southern blot is the classic method used to detect large deletions in mitochondrial DNA, it is not always sensitive enough to detect heteroplasmic deletions at low levels leading to results that are not always reliable. Heteroplasmy refers to the presence of more than one mitochondrial DNA in an individual. The presence of a mutation in the mitochondrial DNA can create an intracellular heteroplasmic mix of mutant and normal mitochondrial DNA. Cells with a higher rate of cell division like blood can yield inconclusive results in southern analysis because heteroplasmy favors wild type mitochondrial DNA. Thus, non-dividing cells such as muscle cells are preferred for the analysis.
Answer: The main reason why only 2 molecules of NADH is formed during glycolysis when it appears that as many as a dozen could be formed is because during glycolysis,most of the free energy that are available from the oxidation of glucose remains in one of the products of glycolysis known as pyruvate which acts like glucose but doesn't undergo metabolism.
Glycolysis is the splitting of sugar molecules into useable/ manageable forms,it can also be seen as the aerobic catabolism of sugar inorder to produce energy in the form of ATP,NADH and PYRUVATE.The following are the products of glycolysis; pyruvate,2 molecules of ATP and 2molecules of NADH.
Pyruvate are used in aerobic respiration or anaerobic respiration if oxygen is not available.
