Answer:
A neuron receives stimuli consisting of the response of thousands of neurons. Synapse is the signals entering the neuron via junctions called. The role of the synapses are to modulate the signal strength and determine the input signal is either excitatory, promoting the neuron to fire, or inhibitory, tending to prevent the neuron from firing.
At the axon hillock the neuron integrates the inputs and if this total is excitatory then the neuron fires. Although this brief description leaves out much of the complexity, it is still remarkable that out of this web of electrochemical firing units, emerges our very conscious.
What you would expect to hear is a polyphonic high-pitched wheeze which can usually be heard at the end of exhalation. But take note that the intensity of the wheeze is not a good indicator for severity. Usually, when there is severe airway obstruction, the lungs are actually silent upon auscultation.

Answer: OC. The fetus begins to move to a head-down position.
Explanation: This happens after other features of the baby are also finishing development, such as eyelashes and eyebrows. The lungs are also the last major organ to finish developing during this time.
1. True: asexual allows for rapid reproduction
2. False: increases genetic variation in a population
3. False: sexual reproduction creates more genetic variation
4. True: during meiosis, the genes can combine differently. See punnet squares and genetics (Mendel's pea study)
