As you walk barefoot in the park, your nose conveys to your brain the smell of the freshly cut grass, your skin sends informatio
n about the feel of the gentle breeze, and your ears transmit the sound of children laughing on the playground to your auditory cortex. This process of acquiring "raw data" about the stimuli in the environment is called _____.A. sensationB. selective attentionC. sensory adaptationD. cognition
<em>A sensation</em> is a mental process (like hearing, seeing or smelling) resulting from the immediate external stimulation of a sense organ often as distinguished from a conscious awareness of the sensory process, it's a physical feeling or perception resulting from something that happens to or come into contact with the body. Considering the example given the freshly cut grass, gentle breeze and sound of children laughing are the physical feelings stimulating your nose, skin, and ears.
<em>Selective attention</em> is focusing on a particular object in the environment for a certain period, in your example, the subject is not specifically focusing on one thing at the time.
<em>Sensory adaption</em> is the reduction in sensitivity to a stimulus after constant exposure to it, in this case, the subject is nos experiencing awareness of a constant stimulus.
<em>Cognition</em> is the process of acquiring knowledge and understanding through thought, experience, and the senses. In your example, the data obtained by the subject is still not processed.
I hope you find this information useful and interesting! Good luck!
If there wasn't a lot of organisms and energy in the productive part of the triangle, then there wouldn't be a lot of third level organisms. The energy piramid would be a lot smaller then what it is here, and maybe if the energy source was low then there might not be such a vast varity of animals in the ecosystem.
Hubble's brilliant observation was that the red shift of galaxies was directly proportional to the distance of the galaxy from earth. That meant that things farther away from Earth were moving away faster. In other words, the universe must be expanding.
