Fish hatchery workers know that if they want artificially spawned salmon to return to a specific stream to spawn when they reach
adulthood, the workers have to raise the fry (baby salmon) in water from that stream during a certain critical time in their early development. This is a clear demonstration of _____. a. trial-and-error learning
b. operant conditioning
c. imprinting
d. habituation
Imprinting is the object of study of ethology, which is related to animal behavior. In the early stage of an animal's life, imprinting is an essential and most conducive phase for learning and subsequent development. The two main types of imprinting are sexual and filial. In sexual imprinting, a young animal learns the traits it seeks in a mate. Affiliate imprinting is the learning of a offspring from his / her parent.
In the case of the salmon fish situation, the need for workers to raise fingerlings (salmon) in stream water during a certain critical period in their early development is an example of imprinting. In this case, imprinting is necessary for the development of this animal in a different environment from the one it was raised.
Answer:Magnetic forces are stronger closer to magnets. The Wednesday test launch stored more potential energy, and launched the spacecraft at a faster speed because the stronger magnetic field closer to the magnet resulted in a greater increase in potential energy.
When there is either a partial or complete tearing on ligaments that are responsible for supporting the joint of the ankle then it causes an ankle sprain.
Based on the exam findings as well as the loss in functionality of the ankle, an ankle sprain can be categorized as grade I, II or III.
In the given situation the 14-year-old girl has a grade II ankle sprain which is characterized by an incomplete tear of the ligaments along with moderate pain (as she rates it 5/10), moderate tenderness, loss of range of some functions, and swelling.
All of the characteristics of the sprain resemble those of the grade II ankle sprain tear and hence, it is characterized as a grade II ankle sprain.
