What information can single cell RNA sequencing tell you that bulk RNA sequencing cannot?

Below is shown a summary of a single cell RNA sequencing experiment where zebrafish embryos of different stages were subjected to single cell RNA sequencing, and cells (dots) were clustered based on their RNA transcript profiles via a Uniform Manifold Approximation and Projection (UMAP). The color coding represents the different embryonic stages as shown at the bottom of the figure (numbered for reference). Use the graph above to determine whether each statement is true or false. Forebrain cells have an RNA transcript profile more similar to the epidermis than the axial mesoderm [blank1]. By stage “6,” future forebrain and epidermis cells are transcriptionally distinct from each other [blank2] Cells in stage “3” and stage “5” embryos are not transcriptionally distinct [blank3] On the level of transcription, cells in stage “1” embryos are relatively less distinct from each other than those in stage “4” embryos [blank4]

Which of the following statements is an example of a negative feedback loop regarding changes in global climate?  

Suppose, in a minimizing problem, the TRUE minimum value of the cost function C*(n) via a node n is 30, and during an A* search the estimated cost function C1(n) with a heuristic h1 is 20 but with a different heuristic h2 it is 25. Which heuristic h1 or h2 is preferable in this case?

What is the typical data structure for Best First search?

What is the Predicate logic sentence for “every dog has four legs.”
