Drag each tile to the correct box.<br> Arrange the layers and faults from oldest to youngest.
kaheart [24]

The answers would be:

Layer D

Layer C

Layer B

Layer A

Layer E

Fault F

If you'd like to know why, here's more about the question:

The law of superpo sition states that the lower the layer, the older the rock is.

Looking at the layers alone, we can say that D is the oldest, and C would be next, so on and so forth.

The law of cross - cutt ing relationships, on the other hand, states that a geologic event, like a fault, is younger than the layer that it goes through.

So if we look at the figure given, the fault goes through all the layers, so we can say that it is younger than all the layers.

gtnhenbr [62]

The question is incomplete. The complete question is:

Question: Impulses originating in the part of the brain called the medulla would most directly affect which body structure?

a. A leg muscle

b. A ligament

c. An arm bone

d. The heart

Answer:

d. The heart

Explanation:

The medulla oblongata contains a number of reflex centers for regulating vital body functions such as heartbeat, breathing, and vasoconstriction. The medulla contains several nuclei, a collection of neuronal cell bodies.

For example, impulses originated in the cardiovascular center regulates the rate and force of the heartbeat and the diameter of blood vessels. Impulses from the cardiovascular center flow along sympathetic and parasympathetic neurons. An increase in sympathetic stimulation from the cardiovascular center of medulla increases heart rate and contractility while a decrease in sympathetic stimulation decreases heart rate and contractility.
