When a nerve impulse reaches the end of the first neuron (presynaptic terminal), various neurotransmitters are released from the same, into the area between the two neurons, called as a synaptic cleft. From synaptic cleft, these neurotransmitters are picked up the postsynaptic terminal of the second neuron, which leads to an impulse.
Answer:
A limiting factor is anything that constrains a population's size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources.
Crossing over is the main event in meiosis and heredity as it leads to genetic variation.
<h3>What is genetic variation?</h3>
Genetic variation is the changes that take place in the genes of individuals that can lead to the formation of new characters.
it generally occurs in meiosis specifically during crossing over.
Thus, it can be concluded that crossing over between non-sister chromatids during meiosis is significant in heredity as it leads to genetic variation.
