Answer:
Axons with high diameter, and myelinated will conduct action potential faster.
Axons with low diameter but myelinated will be relatively slow in the speed of action potential transmission
Axons with high diameter and unmyelinated will be relatively slow in action potential transmission.
Axons with low diameter, and unmyelinated will conduct action potential slowly .
Explanation:
Diameter of Axon affects conduction speed of Action Potential; the thick axons with high diameter conducts action potential at a faster speed than thin neurons. This is because of the less resistance to the transmission of action potential along the thick axon. However, thin neurons with lower diameter has more resistance to the action potential conduct along the axon, thus the speed of transmission is slow.
Myelinated neuron transmits action potential faster because of jumping of action potential at the nodes of Ranvier where there is highest concentration of all channel proteins and pump proteins, Therefore action potential is conducted at a faster rate as it jumps from one node to another. This is salutatory conduction. It increases the conduct about 50 times compare to unmyelinated neuron. In neuron of human it increases the speed to 100ms-1
.Conversely, unmyelinated neurone conducts action potential slowly. About 0.5ms-1 . This is because no salutatory conduction takes place because there is no myelin interruption as Nodes of Ranvier
Answer:
the heart is separated into two sides so that it can carry out its function well. The right heart contains deoxygenated blood and the left heart with oxygenated blood. the two sides are separated from each other so that the blood from the two sides don't get mixed. this leads to effective oxygenation of the deoxygenated blood in the right heart through pulmonary circulation and effective oxygenation of the tissues in the different parts of the body by the oxygenated blood of the left heart through systemic circulation.

Answer:
Option A
Explanation:
Autosomal dominant means that even a single affected allele in genotype of offspring can cause the disease.That means one carrier parent is sufficient to pass on the autosomal dominant disease to its next generation.
Given –
Woman is taster and father is nontatster. They mate and produce a nontaster daughter.
Hence, the genotype of the parents would be
Mother – XX’
Father – Y’X
Here allele “X” represents the non taster allele while the allele “ X’ and Y’ ” represents the taster allele
Cross between XX’ and Y’X
XY’, XX, X’Y’, XX’
Thus, the parents will have a taster boy
