Scientists use a two-name system called a Binomial Naming System. Scientists name animals and plants using the system that describes the genus and species of the organism. The first word is the genus and the second is the species. The first word is capitalized and the second is not.
The vacuoles are the membranous sacs which are filled with fluid. These spaces inside the vacuoles are free of the cytoplasm and are lined by the membrane. These vacuoles serve the purpose of storage, digestion, ingestion, and excretion. The vacuoles allow the plant cells to attain big size without the accumulation of the bulk.
The vacuoles are present in both plant and the animal cells, however, their size in plant cells is larger. No proteins or microtubules composes these vacuoles.
Hence, the blank can be filled with 'membranous sacs'.

Answer:
4 nucleotides.
Explanation:
Basic building block of DNA is known as nucleotides, and they are composed of one phosphate molecule, a sugar, and four bases (guanine, adenine, cytosine, and thymine).
Purine bases is adenine and guanine they contain double ring structure, and pyrimidine bases is cytosine, and thymine they contain single ring structure. The nucleotide bases of DNA line up together, so that the phosphate, and sugar molecule make two long backbones, and each strands of DNA.
