Answer:
C. habituation trials continue after the response has disappeared.
Explanation:
habituation involves the complete elimination of a particular response (i.e, zero frequency of occurrence). If the stimulus cintinues to be presented for an additional number of trials, then, although no further changes occur, the response will exhibit lower levels of recovery (e.g, spontaneous recovery is reduced) as if the response would have fallen below a zero frequency.
Answer:
(A) -> (D) -> (C) -> (B)
Explanation:
First off, given that the problem requires us to explain how life on Earth may have arisen <u>from terrestrial origins</u>, we can discard sentence (E), as impacts from meteorites would count as extraterrestrial origins.
Then it's just a matter of describing the steps by which simple compounds turned into more and more complex structures, that would in turn lead to the origin of life.
Simple inorganic compounds (such as CO₂, or NH₃) were exposed to energy, because of that they formed simple organic molecules, like carbohydrates or amino acids.
These organic molecules, in turn, would self-assemble into more complex structures, such as proteins.
Lastly, there's the phenomenon of Compartmentalization, where large organic structures became enclosed within a membrane-like structure, separating them from the 'outside' medium and thus creating primitive cells.
Answer:
Rhodopsin is the photopigment in rods.
The problems that will receive priority are the physiological needs such as air, food and water.
Maslow's hierarchy of needs is a theory in psychology which organizes people's needs according to their priorities. It is represented as a pyramid with five steps which include: physiological(at the base), safety, belongingness, esteem and self actualization.
The physiological needs at the base of the pyramid are the first priorities.
