Answer:
a) One will check out for flagella or cilia
b) One will check out for the presence of absence of a nucleus.
Explanation:
Organisms that live in water bodies such as the pond described in this question are called AQUATIC. These organisms possess certain structures that enables them swim along the water current. These structures can include a FLAGELLA, CILIA etc. Hence, in order to determine, with the aid of a microscope, whether an organism from a pond can swim, one will look out for the presence of structures like FLAGELLA OR CILIA.
Also, the cells of organisms can either be prokaryotic or eukaryotic depending on whether they possess a membrane-bound nucleus. An organism without a membrane-bound nucleus is PROKARYOTIC while one with a membrane-bound nucleus is EUKARYOTIC. Therefore, the presence or not of a MEMBRANE-BOUND NUCLEUS is the criterion to determine if an organim is eukaryotic or prokaryotic.

six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. Five elements are less frequently so classified: carbon, aluminium, selenium, polonium, and astatine.
Answer:
The answer is A.
Explanation:
Scientists repeat the same experiments because they wanna try to see if they keep getting the same result. When a scientific investigation is repeated, this is called replication. Replication is important in science so scientists can “check their work.” The result of an experiment is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.
