In sexual reproduction how do the offspring compare to the parents
Diano4ka-milaya [45]
Well, if you want to get scientific about it, when two people have a kid, parts of what make them who they are go to that child, and the kid becomes a part of the parents. Basically, they have similar DNA. 
 A non scientific description of that would be they all have similar personalities because the mom and dad passed on some of them to the child. The child would be most alike to their parents by the subconscious actions they take, for example: how they take a shower. For kids who have step parents (me being one), if they grew up with that parent, they eventually adopt things the parent find interests in. Basically, the answer is in the subconscious actions they take and their personalities. <span />

In numerous studies, treatment of prion preparations with ionizing and UV radiation does not reduce transmission of disease; how
mel-nik [20]

Answer:

A. Prions do not contain genetic information, which is affected by ionizing radiation.

B. Denaturants may affect the tertiary structure of prions.

C. Prions are proteins.

Explanation:

Prions are the proteinaceous infectious particles that cause many degenerative diseases of neurons in both animals and humans. They consist of only protein and no DNA or RNA. Due to the absence of DNA or RNA as genetic material, these infectious particles are resistant to ionizing radiation. Ionizing radiations affect nucleic acids of pathogens to destroy them.

Denaturation of proteins affects their secondary and tertiary structures and leave them non-functional. Denaturation may be caused by changes in temperature, pH, disturbance of hydrogen bonds, etc. Therefore, to destroy prions, they need to be denatured.
