What is the correct arrangement of the bones of a vertebral column starting from the brain to the legs? a. cervical (7 vertebrae), thoracic (12), lumbar (5), sacral (5) and coccygeal (4)b. coccygeal (4 vertebrae), sacral (5), lumbar (5), thoracic (12), cervical (7)c. lumbar (5 vertebrae), cervical (7), coccygeal (4), sacral (5), thoracic (12)

The correct answer is A

Explanation:

Total there are 206 bones in humans which are categorized into axial skeleton and appendicular skeleton. Axial skeleton consists of 80 bones and appendicular skeleton consists of 126 bones. Vertebral bones are part of axial skeleton.Total there are 26 vertebral bones:

Cervical - 7

Thoracic - 12

Lumbar - 5

Sacral - 1 (5 bones fused to become one)

Coccygeal -1 (4 bones fused to become one)

So we can write the vertebral formula as follows C7 T12 L5 S(5) C(4)

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
