Answer: Option B) Antigens
Blood typing is based on the presence of proteins known as antigens on the outer surface of the red blood cell plasma membrane.
Explanation:
Blood groups A, B, AB, and O are determined based on the antigen-antibody reactions between donor and recipient bloods.
For instance,
- Blood type A has antigen A on its plasma membrane
- Blood type B has antigen B on its plasma membrane
- Blood type AB has both antigen A and antigen B on its plasma membrane
- while blood type O has neither antigen A nor B on its plasma membrane
So, antigens is the answer

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.
