A.
Explanation:
Predator-prey relations refer to the interactions between two species where one species is the hunted food source for the other.
Both parents are normal. But, some of the kids have the disease. This indicates that the parents are heterozygous for the disease (let's use Dd). They are phenotypically fine because D is normal. But we know they must both carry the diseased d allele because their kids have the disease.
If you cross Dd x Dd you get DD, Dd, Dd and dd as the possible outcomes. But because each time they have a child they roll the dice as to which of the 4 above happens, they were unlucky as 3 of those times they got dd for their child...so 3 of them have the disease (and are dd). One is phenotypically normal but could still be Dd or DD.
If a blood exposure occurs while providing a consumer service, the practitioner must disinfect all equipment, instruments, and surfaces with a bleach solution or a disinfectant that has been registered by the EPA that is bactericidal, virucidal, and fungicidal.
Disinfectants are chemicals that kill microorganisms in liquid form. To kill the germs that are present on the surfaces of non-living things, they are typically administered to those surfaces. In order to eliminate infectious microorganisms, disinfectants are typically used in hospitals, kitchens, restrooms, etc.
Disinfectants come in a variety of forms, and the type to employ depends on the type of bacteria involved. When there is a chance that a surface has been contaminated with infectious agents, disinfectants are utilised.
The disinfectant phenol is used to denature and coagulate the proteins of microorganisms. In domestic settings, phenol is used to clean floors. The efficiency of phenol has so always been likened to disinfection.
