Answer:
Option A, Some people consider embryos to possess rights equal to those of fully developed human beings.
Explanation:
When stem cells are derived from embryo, the embryo dies in lieu to end of its cell development and this happens because stem cells are the only cells that have potential to develop an embryo by producing more stem cells and differentiating them into specific organs.
In most of the study, embryonic stem cells are derived from embryos that are obtained from IVF technique as an spare embryo. But this act is considered unethical as embryos have life within them and hence they also have rights equal to a fully developed human being.
Hence, option A is correct.
For the purposes of this discussion, a neuromuscular junction is a synapse between a motor neuron and a skeletal muscle.
The correct order of a signal being transmitted across a neuromuscular junction is as follows:1. The brain must first send the signal to the muscle that it must move.2. The muscle must then be stimulated by a motor neuron. In other words, the stimulatory impulse must travel from the motor neuron to the muscle via the synapse.
<span>If the command or signal is correctly sent and received via the neuromuscular junction, the muscle will move otherwise the muscle will not move as the brain signal indicated. </span>
