Answer:
The sample contains protein.
Explanation:
Biuret test is a test used to determine or assay for proteins in a solution. When the biuret reagent is added to a solution and it turns blue after 2 minutes, it means that the solution contains protein.
Benedict’s test is used to determine the presence of sugar (reducing sugar) in a solution. When it turns brick red, it means there is the presence of reducing sugar in large quantity.
From the question, since the solution turned blue on addition of Biuret reagent and was also blue on addition of Benedict’s reagent (the reagent is usually blue), it means that the solution contained just proteins excluding reducing sugars.
Flashbulb memories <u>"usually concern events from early childhood
".</u>
A flashbulb memory is an exceedingly detailed, extraordinarily clear 'preview' existing apart from everything else and conditions in which a bit of astonishing and noteworthy (or candidly exciting) news was heard.

Evidence has demonstrated that in spite of the fact that individuals are exceptionally certain about their recollections, the subtle elements of the recollections can be forgotten.
Pump curves give the data about the ability of the pumps to produce the flow against a particular head.
<u>Explanation:</u>
Pump curves are basically information about a given siphon's capacity to deliver stream against certain head. At the point when you're perusing a bend, the siphon's stream rate will be on the top and base and its stature to push is on the sides.
In the system that the framework will have a filter which requires cleaning when the stream rate drops, the steep curve permits more weight drop at a given stream rate as we drop from the structure point.
