The distinction between sensation and perception group of answer choices
a) is important to the understanding of bottom-up and top-down processing
b) allows researchers to identify the "elementary" processes that perception builds upon is clear and
c) allows researchers to distinguish between information processed by the receptors versus the information processed in the cortex.
d) is not always obvious and, thus, does not aid us in our understanding of perception.

Answer:

The distinction between the sensation and perception allows the researchers to distinguish between the information processed by the receptors versus the information processed in the cortex.

Explanation:

The sensation is a process by which the sensory receptors take up the signals or stimuli from its surroundings and send it to the brain through nerves. Whereas, in the process of perception the brain organizes, combines and makes patterns from the given stimuli and gives the response to the particular stimuli accordingly.

Both sensation and perception are connected to each other hence if one doesn’t work then the other automatically stops working.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

not only is it colder, it also becomes darker, less salty, and more dense.
