Explanation:
Iodophor -
Iodophor is a complex of iodine , with solubilizing agents , such as the povidone , surfactant .
And forms a water - soluble material which can release free iodine in the solution phase .
Dilute form of iodophor is used by winemakers and brewers to sanitize their equipment and bottles .
The major advantage of iodophor over other is that , it increases the stability of iodine .
Since enzymes function as organic catalysts, a cell would not be able achieve homeostasis if the required enzymes were not present.
Answer:
The correct answer is b. He determined that DNA contains four nitrogenous bases.
Explanation:
Levene was an American biochemist who studied the structure of DNA in the early 1900s and in 1920 he found that DNA consists of four nitrogenous bases that are Adenine, Guanine, Thymine, Cytosine.
He also found deoxyribose sugar and phosphate group and said that nucleotide is the basic unit of DNA which contains a ribose sugar with attached nitrogenous base and phosphate group.
He also concludes that an equal amount of adenine, guanine, thymine, and cytosine makes the DNA which is now known as tetranucleotide hypothesis. So the correct answer is b. He determined that DNA contains four nitrogenous bases.
Answer:
During the summer months, the water table tends to fall, due in part to plants taking up water from the soil surface before it can reach the water table. The water table level is also influenced by human extraction of groundwater using wells; groundwater is pumped out for drinking water and to irrigate farmland.
