Answers

Answer 1
Answer:

1. According to Health, U. S., 1993: The Annual National Report on Health, the right answer is normally the whorl but it's not mentionned in the propositions.


2. The right answer is CODIS

Combined DNA Index System (CoDIS) is the US national database, created and maintained by the FBI. The CoDIS comprises three levels of information: local DNA index systems (LDIS) where the genetic profiles originate, state DNA index systems (SDIS) that allow laboratories in the same state to share information, and the index system of national DNA (NDIS) that allows states to compare information between them.


3. The right answer is latent prints.

Latent fingerprints are accidental fingerprints left by the skin on a surface, whether visible or invisible at the time of deposit.

Treatment techniques can visualize invisible latent print residues, whether from natural transpiration of the skin or from a contaminant in the blood.


4. The right answer is FACES.

The composite facial is a judicial investigation tool that represents the most likeable portrait possible of the face of a wanted person. It is established from testimonials.


5. The right answer is DNA profiling.

A genetic fingerprint, or genetic profile, is the result of a genetic analysis, making it possible to identify a person from a small amount of their biological tissues (hair bulb, blood, saliva, vaginal secretion, sperm).


6. The right answer is Criminal Investigative Analysis.

Criminal analysis is a method of analysis and investigation in the criminal field based on the use of new technologies (computer science). Criminal analysis distinguishes itself from behavioral analysis (criminal profiling).

Criminal analysis is a method that emerged in the US in the 1960s in the context of the fight against organized crime. This technique allows investigators to create links between elements (individuals, events, places, relationships ...), to structure and prioritize these elements (graphics, maps ...).


7. The right answer is Alec Jeffreys.

Sir Alec John Jeffreys (born January 9, 1950 in Luton, Bedfordshire) is a British geneticist who has developed genetic fingerprinting techniques.


8. The right answer is traditional.

DNA forensic analysis, commonly known as DNA analysis, is less than 10 years old. However, basic science dates back to at least 1953, when two young researchers from Cambridge University, James Watson and Francis Crick, discovered the molecular structure of DNA.


9. The right answer is the mtDNA database.

Unlike nuclear DNA, mitochondrial DNA does not contain repetitive sequences and inter-individual variations are sometimes visible on a single nucleotide. The polymorphism of the mitochondrial DNA is thus a polymorphism of structure (and not of repetition as that of the nuclear DNA).

Forensic analysis is performed on these polymorphisms present in a non-coding region called control region (also called D-loop). The two most variable portions of the control region (HV1 and HV2) are amplified by PCR and then detailed.


10. The right answer is revelancy test.

The revelation test allows to disclose something that was invisible or unnoticed before.

which part of the brain receives sensory stimuli and passes along the information to the other parts of the brain? A. brain stem B. thalamus C. cerebrum D. hippocampus

Answers

The answer is; B

The thallium receives sensory information, such as visual and auditory, processes the information and passes it to requisite areas of the brain such as the cortex. It acts as the hub for the brain were most signals pass through and are channeled. Thalamus  also plays a significant role in sleep and consciousness of a person.


B. The thalamus acts as a relay station, receiving sensory stimulation and passing it along to other parts of the brain.

Which component is present in some viruses but absent in others?

Answers

Answer:

The correct answer would be the virus envelope.

Viral envelope is a protective covering present around the capsid proteins in some viruses.

It is usually derived from the cell membrane of the host and thus it is composed of lipid and viral proteins.

It provides stability to the viral particle, helps in protecting the viral genome, and aids in the fusion of the virus with the membrane of the host.

Examples of viruses in which envelope is present: herpesviruses, poxviruses, flavivirus, hepatitis D et cetera.

Examples of viruses in which envelope is absent: adenoviridae , papillomaviridae , picornaviridae , caliciviridae et cetera.

Hey there

A component that is present in some viruses but absent in others is called envelope. Some viruses have a lipid membrane and other don't.
