Answer:
Sensory Adaption
Explanation:
Stimuli, both external and internal, are sensed with the help of sensory receptors. These sensory receptors sense the change in internal or external conditions called stimuli and send the information to the central nervous system. The sensory information is processed and interpreted in the central nervous system which in turn makes a person aware of the sensed stimuli.
However, the constant presence of the same stimulus does not trigger the firing of the action potential as it occurred during the first few encounters. This is called sensory adaption. For example, chirping of birds is apparent when a person enters the countryside but becomes less apparent after a few days due to sensory adaption of ears.
Answer:
There is no such unique standard method—scientific progress requires many methods—but students in introductory science courses are taught that `The Scientific Method' is a straightforward procedure, involving testing hypotheses derived from theories in order to test those theories.

Both statements are true.
Explanation:
The simple columnar epithelium is characterized by presenting a single layer of cylindrical cells, with the basal and oval nucleus. This type of epithelium is found throughout the entire digestive epithelium, mainly on surfaces with high absorption power such as the walls of the small intestine, but they are also found on secretory surfaces such as the stomach walls, in the gallbladder, in some sections of the collecting tubes of the kidney, in the uterine tube (where it is ciliated) and in the uterus itself.
Squamous Stratified Epithelium is made up of basal cells that are cuboidal or columnar and metabolically active and superficial cells are flattened (squamous). Its function is to protect the underlying tissues in areas subject to nuclei abrasion, this epithelium (not keratinized) forms the wet surfaces of the basal esophagus, oral cavity and vagina. The oropharynx and the pharynx itself are lined by a stratified squamous epithelium as well.
