Out of the following given choices;

A. unimportant; no medical attention

B. stable; the R.I.C.E. formula

C. severe; immediate medical attention

D. severe; the R.I.C.E. formula

The answer is C. Head injuries should never be overlooked. This is because the brain could be damaged yet it is the most important organ of the body. Many symptoms of serious brain injury won’t appear right away. Some injuries result to internal hemorrhage that is not detected then but later causes serious brain damage such as intracranial hematoma.

There are two properties that affect the conduction speed of an action potential along an axon: die axon's diameter and whether

Rom4ik [11]

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

Basaltic magma is very fluid. What type of volcano and eruption would basaltic magma most likely produce?

Dmitry_Shevchenko [17]

The right option is; C. cinder cone, a pyroclastic flow with no explosion

Basaltic magma is a fluid rock material produced from basalt and it has high amounts of iron and magnesium, and low amounts of silica. Basaltic magma is formed within the earth when a part of the earth's mantle is melted. Basaltic magma produces three different types of lava or volcanic deposits which are scoria, ash or cinder, and lava flows.
