anyone know if this two answers are right or not?
1) Bones grow in diameter by the combined action of which two of the three bone cell types?
a) Osteoblasts and osteocytes
b) Osteoblasts and osteoclasts
c) Osteoclasts and osteocytes
d) osteocytes and osteons
I am confused between b and d.
2) According to the sliding filament theory:
a) actin moves past myosin
b) myosin moves past actin
c) tropomyosin moves past actin
d) troponin moves past myosin
I thought the answer is A...but someone keep on arguing with me saying it's B.
