The answer is an open system
The statement that best explains why Chris did not get a rash from the water was that Chris's medication has an antagonistic relationship with the toxin in the water. That is option B.
<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.

Answer:
Microfilaments, Intermediate filaments and microtubules
Explanation:
Three distinct elements make up the cytoskeleton in eukaryotic cells are:
1. Microfilaments or actin filaments which are composed of actin proteins. The functions of those filaments are: muscle contraction (myosin heads move “walk” on actin filaments), the movement of the cell, intracellular transport, maintaince of the cell shape..
2. Intermediate filaments which can be made of vimentins, keratin, lamin, desmin… Their functions are: the maintenance of cell shape, anchoring organelles, structural components of the nuclear lamina, cell-cell and cell-matrix junctions…
3. Microtubules are filaments polymers of alpha and beta tubulin. Their roles are in intracellular transport (associated with motor protein dyneins and kinesins), formation of the axoneme of cilia and flagella, formation of the mitotic spindle.
Oxazolidinones, Ansamycins, and Tetracyclines
These class of antibiotics are mean't to disrupt bacteria that are gram positive.
I believe <u>B.) Analogous structures show that living in similar habitats doesn't lead to similar adaptations </u>is your right answer.
