Answer:
Heyya!
Human development is a slow and gradual process. There seems to be slow and gradual change that becomes abrupt change. The mind has many connections and works according to past habits. A person who seeks to improve themselves will gradually change specific areas within their life. After a while there is a cascade effect that causes linked areas to be altered. Skills and methods that required practice and habit forming transition to being a natural part of life. When the personality suddenly changes, I use the term evolution. Whenever one occurs, the person will probably see their past self as problematic.

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.
