An aquifer is a rock layer that stores and allows the flow of groundwater. Compared to other types of rock layers, how permeable
AVprozaik [17]

Highly porous and permeable

Explanation:

Compared to other types of rock layers, an aquifer is highly porous and permeable.

Aquifers are always the target when prospecting for ground water in a formation.

  • Porosity is the amount of void spaces in a rock.
  • Aquifers are highly porous .
  • Permeability is the inter-connectivity of the void spaces and their ability to transmit fluids.
  • Aquifers have very high permeability compared to other rock types.

In terms of permeability and porosity, an aquifer is higher porous and permeable.

After arousal by a sensory stimulus, consciousness can be maintained by positive feedback, because of activity in the
KIM [24]

Answer:

This question lacks options, options are:

A) cerebral cortex.

B) basal nuclei.

C) sensory pathways.

D) motor pathways.

E) All of the answers are correct.

The correct answer is E.

Explanation:

The cerebral cortex processes and filters its information before passing the most relevant aspects to other regions of the brain. Some of these brain regions, in turn, send information back to the cortex. These loops, known as 'feedback systems', are considered essential for the functioning of cortical networks and their adaptation to new sensory information. Neural circuits must first assess the importance of incoming sensory information and then refine how it is processed in the future. Positive feedback, triggered with the purpose of amplifying the response to the initial stimulus, can be compared to a chain reaction or a vicious circle. Few are the functions regulated by this mechanism; rather it is triggered in pathological situations. It is the system by means of which the organism very rarely regulates any of the bodily functions under normal conditions, making the initial stimulus to be maintained and even increased. This type of mechanism is predominantly present in pathological situations: Its constitutive elements are: stimulus, receptor, afferent pathway, integrating center, efferent pathway, effector and response. The response does not have the ability to satisfy the initial stimulus.
