When you combine sulfuric acid with sugar, you will obtain a reaction. Watch the video segment "Candy Shop" with the sound off. This video segment shows the reaction between sulfuric acid and sugal. Describe
when
you know that the initial chemical reaction has taken place, and describe further changes and how you
know that they are occurring.

This question is incomplete

Explanation:

This question is incomplete because of the absence of the video. However, the addition of sulphuric acid (H₂SO₄) to sugar produces what is known as sugar charcoal through the process of dehydration of the sugar. The process described below should be similar to what is in the video as the process is the same and provides the same result.

When the acid is added, there is a change in the colour of the sugar from white to brown (evidence of initial reaction) and then subsequently black (further change). As the reaction continues, there is an observable increase in size of the sugar (further change and how we know reaction is occurring).

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
