The right answer is D) 9 groups of 3 microtubules
Centrioles are the constituents of a so-called centrosome structure: every animal cell has a centrosome, which is made of two centrioles and which together form a functional unit. A centriole consists of nine triplets inclined microtubules, surrounded by a number of proteins.
I believe the answer is all of the above
<u>Answer</u>: A plate tectonics
B glacial advance
Both plate tectonics and glacial advance and extensive geological phenomena that have the power to affect rock layers in the observed manner. Through the movement of the tectonic plates, rock layers can not only be folded, but also created or destroyed.
The enormous mass of ice contained within glaciers with a thickness of 3 to 4 km, is more than enough to warp and scratch rock layers. They have also moved large amounts of rock many kilometers from their original location.
