The answer is Mullerian mimicry.

Mullerian mimicry is a kind of mimicry in which two or more poisonous animals generate identical presences as a shared protective tool. The theory behind this is that if a predator learns to avoid one of the poisonous species, it will also avoid the mimic species as well.

It is a natural process in which two or more often repugnant species, which may or may not be closely associated and share one or more common predators, have started to mimic each other's cautionary signals, for their communal benefit, as predators eventually learn to avoid all of them.

Stels [109]

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.
