1) a five carbon ribose sugar
2) a phosphate molecule

Explanation:
The cell nucleus is a membrane-bound structure that contains a cell's hereditary information and controls its growth and reproduction. The main function of the cell nucleus is to control gene expression and mnedite the replication of DNA during the cell cycle.
Fungi is single celled micro organism, which grows in plants or soil. Fungi can be mostly found on soil or dead plants or dead matter.
Three characteristics of Fungi are:
- Fungi reproduce through spores.
- Fungi are mostly Eukaryotic or single celled.
- Fungi can play major role in recycling.

I think the correct answer would be option A. If researchers want to use eDNA to look for an invasive species in a waterway, then the first they should do would be to collect water samples from the waterway in question. In any experimental research, it is always collecting samples the first step before getting any results. You cannot execute experiments without any samples and consequently you will not have any results. For this problem, the researchers would not be able to stain the gel, compare the samples and cut the DNA when samples from the waterway are not collected.
