A blue solution turns yellow when it is exposed to a weak acid. A small amount of this blue solution was added to a test tube of
water containing an aquatic snail. The color of the water in the tube changed from blue to yellow after 30 minutes. A possible explanation for this color change is that the
A possible explanation for this color change could be the acid present in the Snail slime has brought the color change.
Explanation:
Snails are Gastropod molluscs.
They secrete a mucus like watery slime to adhere to the surface .
Snails also use their slime as a defense.
Chemical analysis of snail slime suggested that it contains hyaluronic acid and glycolic acid along with other components.
Thus we can state that snail slime is acidic in nature.
In the given question it is stated that the blue solution turns yellow on adding a weak acid.
So when the color of water changed from blue to yellow after 30 minutes, we can assume that the colour change was caused due to the slime secreted by Aquatic snail that was introduced into the tube.
Well all cells in a multicellular organism have the same exact DNA (except for sex cells). But what makes each type of cell different physically and functionally is the genes that are expressed in those cells.So for like example a different section of the DNA molecule is expressed in a nerve cell than a skin cell.
