Answer:

D, The white blood cells of sick people may not be able to efficiently handle the weakened or dead form of the pathogen.

Explanation:

Vaccinations are essentially just weak diseases we use to create antibodies so the body can protect itself from the full disease. If it sees it once, it can defend itself, is the theory. This is choice D.

Why not A: The weakened form will be attacked by the immune system, but maybe not enough, because the person is so sick that the immune system is busy elsewhere.
Why not B: The medication is not what combines with the vaccine to cause problems. It is the body being overworked.
Why not C: The digestive system isn't the issue. You don't eat diseases.

Under which type of change in the ecosystem ( fast change or slow change) would more organisms be able to survive and why?

TiliK225 [7]

Answer:

slow change

Explanation:

If the change is slow they have time to adapt. An example of a fast change is human deforestation. With their habitat suddenly removed, the organisms living there will have to find new shelter and food fast. It's likely that they'll not even be able to find anything to survive off of and die, because organisms tend to have very specific needs. For example, pandas would go extinct if bamboo was eradicated.

Freshwater fish would not be able to adapt if it was suddenly dropped into salt water. They would die. An example of a slow change would be the slow addition of salt to freshwater. Fish that are better able to survive within higher levels of salinity will be more likely to reproduce. Slowly through reproduction a new type of fish suited to salt water may be developed over several generations.
