Question

a preserved specimen of the marine protist g. conglobatus collected from the south atlantic has been identified as the species lectotype, a term —— that this specimen serves as the basis for all formal scientific descriptions of the species. which choice completes the text so that it conforms to the conventions of standard english? a is indicating b has indicated c indicated d indicating

Explanation:

In scientific naming and description, when a specimen serves as the basis for all formal scientific descriptions of a species and is a lectotype, the common - language phrase to use is "has been designated as". "Is indicating" and "indicating" are not correct usages in this context as they do not convey the act of formal designation. "Indicated" alone is also not the appropriate verb form for this formal scientific context.

Answer:

B. has been designated
