All the following statements are true Except: A. Spindle fibers are composed largely of microtubules. B. Centrioles consist of nine triplets of microtubules arranged in a circle. C. All the eukaryotic cells have centrioles D. All the eukaryotic cells have a spindle apparatus.

C. All the eukaryotic cells have centrioles.

Explanation:

All statements are true except C option because plant don't have centrioles.

It's true that spindle fibers are made up of microtubules. Nine triplets of microtubules arranged in a circular form made the centrioles which is component of centrosome in the cells. Spindle apparatus is present in all eukaryotic cells.

So, the only option left is C in which exception is that plant cells don't contain centrioles.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
