You perform an ELISA to test hospital soap samples for contamination with Pseudomonas aeruginosa. Other than the different molecule of interest, this ELISA works exactly like the one you saw in the video. You run the soap sample, a negative control, and a positive control, all in duplicate. How would you interpret the following results?a) The soap is POSITIVE for the Pseudomonas aeruginosa antigenb) You cannot interpret the soap data, because the POSITIVE control didn’t work. c) The soap is NEGATIVE for the Pseudomonas aeruginosa antigen. d) You cannot interpret the soap data, because the NEGATIVE control didn’t work.

Which format should he use to present his data?

The construction of phylogenetic trees is a mapping out the proposed divisions and common ancestors of all living species. traditionally, these trees have been built using morphological data, such as appearance and embryology. recently, it has been possible to construct these trees using molecular data. phylogenetic trees based on different types of information agree with each: that there is strong evidence of a real underlying common descent. this phylogenic tree is composed based on molecular data (rrna). what statements can we infer are true about the organisms throughout the tree? because the tree is rooted, all branches share a common ancestor. all organisms have some sort of cellular structure/organization. all eukaryotes evolved from bacteria. since the organisms contain rna, they share the same dna. if the organisms contain rna, the share the same four nitrogen bases.
