Answer:
eukarya
Explanation:
so long as that stands for eukaryotic
fungi is eukaryotic
other 2 are multicellular, and therefore eukaryotic
if u don't like the first explanation, the second one is process of elimination
archaebacteria is a kingdom, so it can't be that, same with plantae.
fungi isn't a bacteria so it can't be that either
only option remaining is eukarya
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.
