Problem: Text: Ninhydrin (2,2-dihydroxyindane-1,3-dione) is a chemical used to detect ammonia or primary and secondary amines. When reacting with these free amines, a deep blue or purple color known as Ruhemann's purple is produced. Ninhydrin is most commonly used to detect fingerprints, as the terminal amines of lysine residues in peptides and proteins sloughed off in fingerprints react with ninhydrin. It is a white solid which is soluble in ethanol and acetone at room temperature. Ninhydrin can be considered as the hydrate of indane-1,2,3-trione.

Question: can ninhydrin be a useful indicator of proteins?
A: yes

Problem: Text: Slasher employs a season-long anthology format, with an overarching mystery storyline that will be resolved upon the season's conclusion. Aaron Martin, the series' creator/producer, acknowledged gaining inspiration for the format from American Horror Story, stating that, should Slasher have subsequent seasons, the AHS style of self-contained storylines would be used along with, ideally, the reliance on as many actors from previous seasons as possible to portray brand new roles.

Question: are season 1 and 2 of slasher related?
A: no

Problem: Text: Once the tower is built, the person who built the tower gets the first move. Moving in Jenga consists of taking one and only one block from any level (except the one below the incomplete top level) of the tower, and placing it on the topmost level to complete it. Only one hand should be used at a time when taking blocks from the tower. Blocks may be bumped to find a loose block that will not disturb the rest of the tower. Any block that is moved out of place must be returned to its original location before removing another block. The turn ends when the next person to move touches the tower or after ten seconds, whichever occurs first.

Question: can you take from the bottom in jenga?
A:
yes
