#11.) Phacops. It lived in the late Devonian Period (~400 million years ago).
#12.) Carbon-14 is a good radioactive isotope for determing the age of artifacts from a burial site thought to be associated with the most recent early humans because it is present in all organic matter (which humans have, of course).
#13.) 3, Devonian.
#14.) From the Devonian Period through the Triassic Period.
#15.) Cenozoic.

So, we can elminate plants because they can photosynthesise; bacteria because they are prokaryotes and can photosynthesise; archaea because they are prokaryotes; hat leaves us with animals and fungi because these cannot photosynthesise and are both eukaryotes.
But, we cannot skip information. It is also said that the organism found has a cell wall, and animals do not have cell walls.
Answer:
C.
Image 4 -
Option 1 = cilia
Option 2 = flagella
Option 3 = pseudopods
Option 4 = pili (they're a meant to attacht to surfaces only bacteria)
Image 5 -
Runner stems are those that grow horizontally, therefore the fourth image with the long horizontal stems.
Rhizome stems are underground stems that can form roots or shoots through their nodes. Therefore, the third image with white background (the one with 2 drawn plants).
Tuber stems are large underground (mostly) structures used as storages for the plant. Therefore, this corresponds to the first image (the one with the white background.
Bulb stems are short and "bulby" stems, whith thick, leaves. Therefore, the second image (the one with the grass background).
