Answer: first continuous, then partial
Explanation: Continous reinforcement refers to a reinforcement schedule whereby every correct response performed is praised or reinforced, here, every time John's pet correctly performs that trick, the active or response of the pet is rewarded, thus will help carry out the correct response due to the reinforcement it receives. However, after sometime the reinforcement should be partial such that the action isn't reinforced every time the trick is performed. This according to the partial reinforcement extinction effect is more erobust than continuous reimbursement.

Answer:
choose between two outcomes that are both desirable
Explanation:
in the course of fish evolution, two of the gill slits slowly advanced into the jaws.
The evolution of fish started about 530 million years in the past at some point during the Cambrian explosion. It become during this time that the early chordates advanced the cranium and the vertebral column, main to the first craniates and vertebrates. the first fish lineages belong to the Agnatha or jawless fish.
The earliest fish, corresponding to living hagfish, developed about 550 million years in the past. Diversifications that in the end advanced in fish include an entire vertebral column, jaws, and an endoskeleton manufactured from bones in preference to cartilage. Fish live in the course of the sea and in freshwater lakes and streams.
New studies have uncovered the genetic foundation of gill covers in fish, which came about over 430 million years ago. It sheds light on one of the most essential evolutionary traits for fish, in addition to over vertebrates.
In jawless fishes, a sequence of gills opened behind the mouth, and those gills became supported by way of cartilaginous elements. the primary set of these elements surrounded the mouth to shape the jaw.

Answer:
Conspicuous consumption
Explanation:
Conspicuous consumption is a term used to describe expenditures on goods and services purchased primarily for the purpose of showing wealth. In the mind of the conspicuous consumer, such display serves as a means of having or maintaining social status before a social group, which socially determines objects and goods, such as a classification of higher or lower status. An example of this can be seen in the question above, where the girl bought a very expensive purse just to show that she possessed something luxurious and give an impression of wealth.
