Ascientist was observing a specimen under a microscope. he obtained the specimen from pond water. he observed that the specimen was egg-shaped, had hairy structures all over its body, and was covered by a membrane. he also noticed two nuclei in the specimen’s body. to which phylum did the organism belong?
a.
sarcodina
b.
ciliophora
c.
apicomplexa
d.
euglenoid

There are three ways you can solve this problem:

1.- You can guide yourself through knowledge, and therefore know the answer. There isn´t much to explain here.

2.- You can eliminate obvious options such as sarcodina or apicomplexa. Euglenoid isn´t an extremely obvious removal since it has a flagela, which can be mistook by a hairy-structure. But, if you do things correctly, obtaining your answer wont be a problem.

3.- You can do an etymologic-guess, which works really well in biology. If you guide yourself this way, you´ll bump into the answer quickly --> "cilio" means hair and according to the description the specimen was covered in hairy structures.

Hope it helped,
