Answer options:
- extraction and observation of DNA
- identification of ribose and deoxyribose
- recognition of RNA as DNA’s messenger
- construction of an accurate DNA model
Answer:
- identification of ribose and deoxyribose
Explanation:
Phoebus Levene was an American biochemist who studied the structure of DNA and RNA. He was able to isolate the sugars (ribose and deoxyribose) from the nucleic acids, which are an important part of their structure.
He also determined how the nucleic acid components combine to form the nucleotides, the basic building blocks of nucleic acids, and how the nucleotides combine in chains to form the polymer.

Answer:
I think it is the last one
Answer:
In muscle tissue
Explanation:
People who exercise daily, their metabolism rate is very high and the consume sugar, proteins and fat as a substrate for providing ATP molecules. The ATP molecules are then utilized by the body to perform physical work.
The physically active people when they require fat in their diets, the fats first will be stored in the muscle tissue as the cells there will use fat as a substrate for providing a large amount of energy that is 1 g of fat will provide 9 kcal.
Thus, muscle tissue is the correct answer.
