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.
The sun's rotation around Earth
The moon's rotation around Earth
Earth's orbit around the sun
Earth's orbit around the sun
Explanation:
The definition of an orbit is a circular shape, the rotation of one full circle or a range of experience. The 365 days it takes the earth to get around the sun is an example of the time it takes for a complete orbit or full circle around.
S phase
G2 phase
Answer: Image result for In which stage of the cell cycle is the cell preparing for division? *
Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA.
Explanation:
If two organisms are present in the same clade, then it predicts that they have evolved from a common ancestor.
Further Explanation:
Cladistics is a method of classifying organisms based on their shared traits. This method is essential for grouping the closely related species, tracing the ancestors, and studying the evolution of various characteristics. In cladistics, these independently evolved characters would be grouped, and the resulting cladogram will show false relatedness among the species.
While constructing clade, convergent evolution, and homoplasy (shared characters that are not received from common ancestors) can pose certain problems. The shared derived characteristics show immediate common ancestry among organisms. It suggests that lineages having some common traits are more likely related according to the evolutionary perspective.
By studying the closely related group known as an out-group, the derived traits can be determined. If a character is derived independently in two organisms, there is a doubt regarding the same ancestry. Thus, there are few chances of grouping organisms with different ancestry together. Two organisms present in a single clade shows that they have mainly evolved from a common ancestor.
