Flowers

Explanation:

Angiosperms are group of seed producing plants that has flowers. They produce seeds which is enclosed in their carpel. They are vascular plants that is they have conducting tissues or vascular bundles which are phloem and xylem which transport nutrients and water in the plants respectively. Angiosperms produce fruits. They are the most diverse and advanced group of plants. They are often called flowering plants. The flowers serve as the reproductive structures.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
