Vacuoles are <span>large saclike, membrane enclosed structure - store materials like water, salts, protrins, and carbohydrates - like a storage unit</span>
Answer: 320 phosphate groups.
<u>Each nucleotide of DNA contains one phosphate group attached to it</u>.Therefore if there <u>were 160 nucleotides in a strand;,definitely each nucleotide of the strand must contain one phosphate group, therefore 160 phosphate groups. must be present.</u>
However, a DNA molecule must contain double strands, therefore 160 multiplied by 2 should give 320 phosphate groups in the alien DNA.
Explanation:
<span>In plants there larger then animal cells. By the time the plant stops growing there's one large vacuole. Sometimes the vacuole can take more then half the cells volume. The vacuole holds a large amount of the plants food and water.</span>
