Which biometric technique is considered nearly infallible from a scientific point of view and is increasingly preferred by crimi

Sergio039 [100]

Answer:

DNA analysis

Explanation:

DNA is unique for all individuals. DNA analysis is the process of analysing the DNA characteristics of an individual.

DNA profiling is used in forensics to identify the suspects involved in criminal activities.

1. In the process, DNA of the suspects is matched with the DNA found in the site of the crime.

2. If a match is found, it indicates that the genetic relationship exists between the suspect and the criminal or the crim.

3. The order from the court is needed to obtain the DNA of the suspects. The sample can be in the form of blood or saliva.

4. The sample obtained should have adequate cells which contain the DNA.

Issues

The DNA obtained from the crime site is not pure or proper enough to be ideal for the DNA profiling.

Degraded sample

1. The sample obtained from the site of the crime is not always adequate to obtain the actual DNA.

2. The sample can be contaminated due to the environmental factors.

3. The sample obtained is too less and hence, should be examined accurately in order not to waste the sample.

DNA mixture

4. The sample obtained from the site of the crime is found to contain DNA from more than one individual.

Profiling types

DNA profiling can be carried out by using any of the techniques mentioned below.

1. RFLP analysis ( Restriction fragment length polymorphism )

This uses the Southern blot technique. The blot process needs a large amount of the sample. Also, this works well only when the sample is not degraded.

2. Polymerase chain reaction (PCR) analysis

3. STR analysis ( short tandem repeats )

4. AFLP ( amplified fragment length polymorphism )

This is an automated and low-cost process. It is easy to set up and operate which makes this process common in low income countries.

All the methods mentioned above have their own advantages and drawbacks.

Destinguish between qualitative data and quantitave

Elden [556K]

For quantitative data, notice the root word 'quantity', which focuses on the amount of something, for example, there are more players on team a than on team b.

For qualitative data, notice the root word quality. Qualitative data focuses on the condition or state of something rather than the amount, for instance, player a does not run as fast as player b.

Hope this helped.

2. (8 points) When creating the Academic Database, there were several instances of data

Bad White [126]

Answer:

See explaination

Explanation:

An Academic Database deals with the information pertaining to the records of students of an institute. The various fields which can be associated with a student are Name, Unique Identification Number, Marks in various subjects, Grades, Courses Taken and so on. Most of the fields mentioned above have some or other form of validation that is required for the DB to be consistent and follow the basic properties of a database.

One field where range validation can be used is MARKS. In the marks field, the range of marks will be say 0 to 100 and anything below 0 or above 100 must be reported to the database administrator. Another field where we can apply a range validation is AGE in which the range of age allowed could greater than say 10, if it is a college and maximum age could be say 60. Thus, the range check on the AGE field is 10 to 60.

One field where choice validation can be used is GENDER. In the gender field, there could be multiple choices like Male, Female and Others. Thus, out of the available choices we have to select only the available choice and only one choice must be selected where we can apply choice validation. Another field is COURSE, where we can have a list of courses a student can opt for and out of the available courses can select one.

Thus, there are multiple fields where we can apply various types of validation and it is important to explore the area for which the DB has been created understanding all the scenarios and attributes of the problems that are associated with that area.
