Answer:
The correct answer is d. hydronium ion.
Explanation:
Hydronium ion is a positively charged molecule that has three hydrogen atom bonded with an oxygen atom. Hydronium ion is formed when the water molecule gains an extra H+ ion from somewhere.
This H+ ion easily form bonds with one of the lone pairs present on the water molecules. H2O is also a polar molecule and has a partially positive charge due to which the extra H+ ions get attracted to the negative pole of water and make hydronium ion. Therefore the correct answer is d.
Function of
centrioles
An organelle that forms a
spindle-shaped structure of protein fibers on which the chromosomes move during
nuclear division are called the centrioles. Centrioles are part of the animal
cell organelles. Hence, they are a small part of the microtubules organized and
set in a particular course. Microtubules include 9 sets. Centrioles contain a
cylindrical structure, packed with protein which is described as tubulin. Found
mostly in eukaryotic cells beside the nucleus.
