Answer:

There are number of methods for determining the fingerprints. However, most commonly used methods are:

  • Photography
  • Alternate Light Source
  • Cyanoacrylate

Explanation:

Determination of fingerprints is an important method used in forensic science.  There are generally three types of fingerprints that are to be determined, namely latent fingerprints, patent fingerprints and plastic fingerprints. There are numerous methods used for the determination of fingerprints. However, most commonly used methods are:

<u>Photography:</u> Photography is direct or straightforward method that is used to determine the patent fingerprints. The image is photographed in a high resolution with the help of forensic measurement scale used as a reference.

<u>Alternate Light Source Method:</u> In this method the light source or LED is used of a particular wavelength in order to determine the latent fingerprints.

<u>Cyanoacrylate:</u> Cyanoacrylate processing is also known as super glue method or fuming method, which involves exposure of cyanoacrylate vapors to the non-porous surface from where the fingerprints are to be obtained.

Which of the following represents a possible chromosome number of a species that uses sexual reproduction, and why?
Ann [662]

Answer:

B. 62, because this number will create a haploid cell, allowing both female and male gametes to be combined.

Explanation:

Sexual reproduction involves two organisms to come together (male and female). Sexually-reproducing organisms make use of a process called MEIOSIS to produce gametes or sex cells, which have a reduced number of chromosomes as the parent cells producing them.

A sexually reproducing organism must contain a complete diploid chromosome number (2n) that allows it to produce cells with a haploid chromosome number via meiosis. The haploid gamete cells that result from each meiotic divisions of male and female parents can combine to form a whole diploid organism.

What is the medical term for the process or procedure that destroys or inhibits disease-causing microorganisms to prevent infect
Simora [160]

Answer: Sterilization.

Explanation:

Sterilization is the process that kills, or deactivates all forms of life so then a product is considered free of viable microorganisms. This process must be designed, validated and carried out to ensure that it is capable of eliminating the microbial load of the product.

Since sterility cannot be demonstrated without causing the complete destruction of the products, <u>sterility is considered when the probability of a product being contaminated is acceptably remote.</u> A critical product is considered sterile when the probability of a microorganism being present in an active or latent form is equal to or less than 1 in 1,000,000 (sterility safety factor 10^-6).

Agents that kill microorganisms are called microbicides or more commonly called "germicides". If the agent kills bacteria, it is called a bactericide. And if it kills fungi, then it is called a fungicide. It is important to consider than <u>after an exposure of the sterilized object to the air or its surroundings, it will have become contaminated again with microorganisms.</u>

Examples of sterilization include physical methods and chemical methods. Physical methods include:

  • Wet heat (in steam autoclave)
  • Dry heat (in sterilization oven)
  • Radiation (gamma radiatio, electron beam, X-ray, ultraviolet, microwave, white light)

Chemical methods include a variety of chemicals in liquid and vapor form, for example:

  • Hydrogen peroxide
  • Chlorine dioxide
  • Ozone gases
  • Ethylene oxide
  • Propylene oxide
  • Peracetic acid
