The skeleton serves six major functions : support , movement , protection , production of blood cells , storage of minerals and endocrine regulation.
So it is TRUE
The answer is B) 9 neutrons
Hypertonic solution: higher concentration outside of cell = lower water potential = water exits cell, cell shrink (crenated-animal cell, flaccid/plasmolysed-plant cell)
Hypotonic solution: lower concentration outside cell =higher water potential = water enters cell, cell swell (animal cell - burst,plant cell - turgid)
Intestinal muscles and heart muscles are involuntary muscles,hand muscles and neck muscles are voluntary muscles
