<h2>
Through production of news cell-surface proteins with a different molecular structure by each new generation. Letter B</h2>
Explanation:
The life cycle of theses paratises extracellular alternate between the salivary glands of the insect transmitter and the blood of the mammal. During the set prior to the entry into the host, the metacylic parasites express a dense over formed by the Variant Surface of Glycoprotein, after entering to the mammal host they transform into a morphology that stays in the bloodstream.
<em>The parasites have to manipulate hosts cells in order to avoid the production of antimicrobial molecules and to benefit from growth factor production.</em>
<em>Intracellular protozoa have a remarkable adaptive capacity as they are able to resist killing by remodelling the phagosomal compartments where they reside and by interfering with the signalling pathway that leads to cellular activation. </em>

<h3>What is drug-drug interaction?</h3>
Drug-drug interaction is definitely as the relationship that exists between two drugs when administered together or at the same time.
This relationship that exists between the drugs could be:
- Synergistic relationship or
A synergistic relationship is the type of relationship that occurs between two drugs where by the total effect of the drugs are greater than the sum of the individual effects of each drug.
An antagonistic relationship is the type of relationship that occurs between two drugs where by the both drugs has opposite effects on the body.
Therefore, Chris didn't have the rash because his medication has an antagonistic relationship with the toxin in the water.
