Answer:
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.
The genome is the complete set of genetic material in a cell or organism
Explanation:
DNA can be extracted by grinding the tissue in dry ice or liquid nitrogen with the mortar and pestel or a food grinder. the cell membrane must be disrupted,so that the DNA is released into extraction buffer.
A. Proteins
Most scientists thought protein was the genetic material because they were macromolecules.
