Answer:
The correct answer is: B, C, D,F, G, H.
Explanation:
Aneuploidy is a defect on the number of chromosomes a cell has. Human cells have 46 chromosomes, an additional chromosome (47) or a missing one (45) is an aneuploidy. Aneuploidy is usually due to a defect during cell division (chromosomes don’t separate). The following disease are examples of aneuploidy:
b. Down's syndrome (trisomy of chromosome 21)
c. Edward's syndrome (trisomy of chromosome 18)
d. Jacob's syndrome (a male with an extra Y chromosome)
f. Turner's syndrome (a female missing a X chromosome)
g. Klinefelter's syndrome (a male with an extra X chromosome)
h. Patau's syndrome (trisomy of chromosome 13)
Answer:
The neck consists of important nerves throughout the body and is also attached to the spine which caused him to become paralyzed.
Explanation:
Answer:
The answer to the question: Where does the stimulus occur in order to initiate an AP, would be, B: Dendrites.
Explanation:
When an impulse is to be generated and passed on as an action potential towards a corresponding neuronal cell, and a final affected organ, the neurons need first to be stimulated so that an action potential begins. This stimulus comes as a neurotransmitter released by other neurons near the one that will be stimulated. This neurotransmitter will bind to the receptors on the dendrites of the neuron to be stimulated and immediately this will cause the ion channels, gated and non-gated, to open and close so that an action potential can be initiated. The cell body then initiates the first action potential, and will in turn stimulate the axon to also start their own action potential, which will, like a domino effect, move down to the axon terminals. This process will be followed all along a neuronal circuit.
