sergejj [24]

Vance is demonstrating conceptual knowledge

Conceptual knowledge is the clear and detailed understanding of principles, concepts, models or theories and the understanding of the linking relationships between them. Conceptual knowledge is acquired by thoughtful, reflective learning, listening, reading, or viewing. From the question, Vance is demonstrating conceptual knowledge because he has the explicit understanding of why rainfall amounts affect different types of vegetation positively and others negatively.

How do the resurection of fern, crysts of brine shrimps and tardigrade survive with no water?
ehidna [41]
They survive without water by entering a special mode, otherwise called as shriveling. They can lose even 95% of water in their body and still live, even though they would look like dead plants, they would actually be alive. In the absence of water, tardigrades use a sugar called trehalose, which becomes their source of life until they find some water.

Wetlands are important ecosystems for many reasons. Select all that apply.
vazorg [7]

A, B, & D.

Wetlands DO NOT increase the rate of extinction of mammals by creating a loss of habitat. Wetlands rather form a habitat for many organisms creating a rich microcosm of an ecosystem.

Explanation:

Wetlands are land areas that are seasonally or permanently submerged in water. They include marshlands, estuaries, deltas, swamps, floodplains, and etcetera.  The plants within wetlands, such as mangrove slow down water runoff hence allowing settling down of, sediments and pollutants hence ‘cleaning’ the water.

Due to this fact that wetlands slow water movement, these ecosystems are significant in reducing flooding by ‘storing’ flood water and releasing it slowly hence acting like flood controls.

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.
