How is sensation different from perception?

To review:
The difference between sensation and perception.
Introduction:
Sensation is the ability to feel something physically. It can be defined as the process through which the senses collect information and then send them to the brain for its further interpretation. The perception, on the other hand, is the faculty or art of apprehension by the means of different senses or mind. It involves cognition understanding.
Explanation of Solution
The difference between sensation and perception is as follows:
S. no | Sensation | Perception |
1. | It is a passive process that collect information from outside world. | It is an active process that involves selection, organization, and interpretation. |
2. | It depends on the surroundings. | It is shaped by learning, expectation, and memory. |
3. | It gathers the changes in the external or internal environment consciously or subconsciously. | It is a conscious interpretation of the sensation. |
4. | Most sensory information never reaches cerebral cortex. | It is a primary function of the cerebral cortex. |
Thus, the sensations have a physical source while the perception is totally cognitive based.

- What is this?arrow_forwardMolecular Biology A-C components of the question are corresponding to attached image labeled 1. D component of the question is corresponding to attached image labeled 2. For a eukaryotic mRNA, the sequences is as follows where AUGrepresents the start codon, the yellow is the Kozak sequence and (XXX) just represents any codonfor an amino acid (no stop codons here). G-cap and polyA tail are not shown A. How long is the peptide produced?B. What is the function (a sentence) of the UAA highlighted in blue?C. If the sequence highlighted in blue were changed from UAA to UAG, how would that affecttranslation? D. (1) The sequence highlighted in yellow above is moved to a new position indicated below. Howwould that affect translation? (2) How long would be the protein produced from this new mRNA? Thank youarrow_forwardMolecular Biology Question Explain why the cell doesn’t need 61 tRNAs (one for each codon). Please help. Thank youarrow_forward
- Molecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB. If you were to do gene therapy to fix this problem, briefly explain what type of gene therapy youwould use to correct this. Please help. Thank youarrow_forwardMolecular Biology Question Please help.
