The __________ is the circulatory structure that handles a relatively low blood pressure and the driving force for the movement of blood is the contraction of skeletal muscles.
Cellular respiration – Releases energy by breaking down gluecose and other food molecules
isotonic – when the concentration of 2 solutions is the same
The __________ is the circulаtоry structure thаt hаndles a relatively lоw blоod pressure and the driving force for the movement of blood is the contraction of skeletal muscles.
frame-shift mutation – The addition (insertion mutation) or removal (deletion mutation) of one or more nucleotides that is not indivisible by three,therefore resulting in a completely different amino acid sequence than would be normal.
