Answer;
-Sensation
Sensation is the activation of receptors in the various sense organs
Explanation;
-Sensation is the activation of sensory receptor cells at the level of the stimulus. Perception is the central processing of sensory stimuli into a meaningful pattern. Perception is dependent on sensation, but not all sensations are perceived.
-Receptors are the cells or structures that detect sensations. A receptor cell is changed directly by a stimulus. A transmembrane protein receptor is a protein in the cell membrane that mediates a physiological change in a neuron, most often through the opening of ion channels or changes in the cell signaling processes.
<u>Answer</u>:
1.a) Species. It is the lowest taxon and represents the scientific name of the organism.
b) The species name is part of the binomial system of nomenclature developed by Linnaeus.
Thus it is composed of two parts each with its own writing rules (ex. gray wolf - <em>Canis lupus</em>):
A. the genus or generic name
- written first
- always underlined or italicized
- the first letter is always capitalized
ex. <em>Canis</em>
B. the specific epithet or species name
- is written second
- always underlined or italicized
- never capitalized
ex. <em>lupus</em>

2. The results should always be the same. A dichotomous key is an identification tool based on a series of choices between alternative characters (dichotomous = divided into two parts). Thus, there is no room for subjective observation that may lead to another result. If the morphological traits of the organism are correctly identified, the the result should always be the same. Any differences occur due to errors on the scientist's part.
