Answer:
A. 1' ... 5'
Explanation:
The pentose sugars present in nucleotides have five-carbon structures. Other components of a nucleotide are a phosphate group and a nitrogenous base. The nitrogenous base in a nucleotide can be a purine or pyrimidine. The purine bases are covalently joined to the 1' carbon atom of the pentose sugar at their N-9. The bond between the nitrogenous base and a pentose sugar is called the N-beta glycosyl bond.
Similarly, N-1 of a pyrimidine base is covalently linked to the 1' carbon of the pentose sugar. The phosphate group of a nucleotide is bonded to the 5' carbon of the pentose sugar.
Answer:
Three elements, carbon, oxygen and hydrogen, are essential to plant growth and are supplied by air and water.
Explanation:
Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.
