The csi investigator's second walk-
is done with the initial responding officer in order to obtain information observed upon first arrival at the scene
includes detailed photography and fingerprinting
takes places before anyone, including the victim, leaves the crime scene
is a time when the csi investigator is collecting as much physical evidence as possible

2. Includes detailed photography and fingerprinting.  

Explanation:

The first walk through involves the designing of a a plan to carry out the process of crime scene.

The second walk through is done for the purpose of documentation. This process includes taking pictures and drawing sketches of the scene. It might also involve taking videos of the scene to assure that every detail of the crime scene is documented.

After this step, evidence are collected from the scene.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
