Answer:

C. Diploid condition

Explanation:

A Karyotype is the pictorial display that shows chromosome arrangement and number in a cell. The Karyotype shows any abnormalities in the nuclear material (chromosomes). In a carrot plant that was cloned from carrot root, the clones should possess the same features as the original plant.

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.
