Answer: Purine
Explanation:
A purine is a nitrogenous base found in nucleic acids, and contains a 6-membered pyrimidine ring fused to the 5-membered imidazole ring. The most common examples of purine bases are adenine and guanine.
Thus, the nitrogen base pictured is adenine, and the nucleotide considered is a purine
Answer:deoxyribose
Explanation: From the information provided, (though the diagram is not shown), the structure is a DNA double helix. A DNA contains deoxyribose sugar thus the name deoxyribonucleic acid. RNAs contains ribose sugar thus the name ribonucleic acid. A deoxyribose is a pentose (a 5- carbon sugar) which lacks one oxygen atom at position two of its carbon skeleton, hence the name deoxy - ribose. It's usually written chemically as 2- deoxyribose.
This is because when Mendel did it, he knew that peas are easy to raise, have plenty of offspring, fertilize themselves, and have varieties in genotype and phenotype that are easily observable.
because a glucose molecule is to large to pass through a cell membrane cells assist glucose diffusion through facilitated diffusion and two types of active transport.
D. Prokaryotic cells do not have a true nucleus or membrane-bound organelles.
