Answer:
When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron.
Explanation:
The binding allows the nerve impulse to travel through the receiving neuron.
Answer:
Examples that show similarities between species DNA show homology and give evidence of evolution.
Explanation:
The answer is <span>5.2 × 10-2 newtons.
To calculate this, we will use Coulomb's Law:
</span>F =
where F is repulcive force, k is constant, Q is charge, r is distance between charges.
