Answer:

A mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology.

hodyreva [135]

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.

Which of the following substances would NOT transport readily in blood?
Levart [38]

The substance that would not transport readily in blood is : Triglycerides ( B )

<u>Although your question lacks some data below are the missing options</u>

  1. Fibrinogen
  2. Triglycerides
  3. Monosaccharides
  4. Albumin
  5. Carbohydrates

Triglycerides are not readily transported in blood but it is contained in dietary fat which is been absorbed by the body through the intestine in the form of chylomicrons ( triglyceride-rich lipoproteins ).

When the chylomicrons gets to the liver, the liver disassociates the Triglycerides from the chylomicrons that is needed by the body for energy.  

Hence we conclude that the substance that would not transport readily in blood is Triglycerides.
