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.
An important role in fungi in an ecosystem is B. Breakind down dead organisms.
Answer:
The sternum, thoracic vertebrae, and ribs protect the heart and lungs.
Explanation:
The skeleton can be divided into the <em>axial skeleton</em> (the skull and the vertebral column), <em>visceral skeleton</em> (ribs and sternum) and the <em>appendicular skeleton</em> (extremities).
The function of the <em><u>visceral skeleton</u></em> is to <em>support and protect</em> the first portion of the digestive and cardio-breathing apparatus.
In mammals, the second part of the vertebral column (thoracic vertebrae), the ribs and the sternum delimitate a protective box for lungs and heart.
B. After a rock is moved by deposition it has to be set down by deposition or it needs to be deposited is another way to think of it.
Answer:
Pigmentation, (skin color), in humans has evolved under selection pressure from the duration and intensity of sunlight. Ancestral populations near the equator were selected for dark skin, while those living in higher northern latitudes were selected for lighter skin.
