Answer:
Mohammed should now <u>lift</u> the print from the surface to preserve it
Explanation:
In order to preserve fingerprint evidence as required by crime laboratory policies and criminal justice systems, for which we have digital photography, casting material, and latent print lifts, that can be used as secondary evidence
The ridges on the cast and lift can be photographed to serve as an additional secondary evidence
The processing of the latent print after photographing is dependent on the surface type and may include the creation of an impression on soap, paint, wax, clay or dust
Therefore, Mohammed used an enhancement technique that made a fingerprint visible on a lamp. He photographed the print. Mohammed should now <u>lift</u> the print from the surface to preserve it
Answer: The blue colour of a biuret solution changes to violet.
Explanation: Biuret solution is a reagent that is used to test for the presence of protein in a substance.
A Biuret solution is composed of sodium hydroxide and copper II sulphate. Copper ions give the reagent its characteristic blue colour. Copper ions react with peptide bonds in the protein in an alkaline solution to form a Biuret compound with a violet colour. The copper ions which have two positive charges are reduced to a positive charge, thereby causing a colour change.
Graph and
table are similar because they both present the evidential and statistic data
given and yielded from a certain experiment or testing. They both have a role
in classification, categorization, interpretation and organization of the data.
A table can be very direct and arranged while graph can be very audience-friendly,
effective and prolific display of the results. Tables can be a system of rows
and columns while graph are representations of objects which can display
relationship however these two tools are relational with each other.
