The first blank can be correctly filled up with the same genetic material and the second blank can be correctly filled up with to contract.
All the cells of the body such as muscle cells, nerve cell, cardiac cell, blood cell et cetera contain the same genetic material. They become specialized cell as a result of cell differentiation.
The function of the muscle cells is to contract which helps in locomotion and movement. Skeletal muscles help in locomotion and smooth muscles help in the function of internal organs such as uterus muscle contracts which help in delivering the baby.
The function of the nerve cells is to transmit signals from receptors to the central nervous system (CNS) and from CNS to effector organs.
