Answer:
A) Divergent evolution because all of the species have similar structures during the first stage of development.
Explanation:
Answer:
lateral; inferior
Explanation:
In anatomical terms:
- Superior is towards the head, and <u>inferior </u>is towards the feet.
- Medial is towards the centre of the body (belly button) whereas <u>lateral </u>is towards the outside of the body (towards the hip bones and arms, for example)
- Posterior is towards the back (spine), whereas anterior is towards the front (belly)
Therefore, the fingers are lateral (to the side) and inferior (lower) than the heart
More than likely mutation
The neuromuscular synapse is a chemical synapse between a motoneuron and a muscle cell (muscle fiber). The neuromuscular synapses consist of:
• the pre-synaptic cell-motoneuron that sends signal by releasing the the neurotransmitter from the synaptic vesicles
• synaptic cleft, place where neurotransmitter is released, between motoneuron and muscle fuber
• post-synaptic cell also called endplate -the muscle cell that receives the signal via receptors.
