Answer:

A. Neither the subjects nor the researchers can bias the results.

Explanation:

As described, a double- blind study is one in which the researcher and his study does not know the person receiving the actual treatment.

Researchers can be bias in their studies as they seek to establish and fine tune results in the way the best favors them. A double-blind study helps to bridge this gap to prevent bias that might be introduced into an experimental set up or while interpreting results.

Which of the following is an example of an adaptation that allows similar species to live in the same environment?

Answer:

B. Both mussels and barnacles live in the tidal ecosystems.

Explanation:

Mussels are small bivalve molluscs that are adapted to both marine and freshwater ecosystems. Barnacles, on the other hand, are arthropods that are adapted to marine ecosystems. However, both are adapted to shallow and tidal zones.

Both organisms are small and have the capacity to live in tidal ecosystems where they thrive and play important ecological roles. For instance, barnacles are filtering organisms, which is extremely important for the food chain, and mussels filter out significant amounts of excess nutrients and metals, that is, they make the water more suitable and clean for organisms to live.

As they are both adapted to tidal ecosystems, this would be an example of an adaptation that allows similar species, in this case mussels and barnacles, to live in the same environment.
