Answer:
DNA
Explanation:
RNA is not a double helix
Uracil is on the RNA, this is a picture or DNA. Uracil is just one of the nucleic bases

It is DNA because it is a double helix structure held together by the four nucleic bases.
The last option is your answer if you had choices
Answer:
Explanation:
A diploid cell becomes haploid during Meiosis I and is completed after Telephase I. These homologous chromosomes (from mom & dad, all duplicated) pair up during prophase I forming tetrads. The pairs of homologs line up on the metaphase plate during metaphase I
At what stage of meiosis are cells haploid?
Prophase II: Starting cells are the haploid cells made in meiosis I. Chromosomes condense. Metaphase II: Chromosomes line up at the metaphase plate. Anaphase II: Sister chromatids separate to opposite ends of the cell. Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid
Answer: digestion and absorption
Explanation:The small intestine is the part of the intestines where 90% of the digestion and absorption of food occurs
