This question is not complete; here is the complete question:
A one-hectare pond is sampled in early September. The sample yields 1 small catfish as well as 17 benthic invertebrates that represent 10 species.
If the pond is resampled a year later, which of the following would best indicate that the pond had been adversely affected by adjacent development?
A. An uncommon species has become more numerous
B. An increase in low-tolerance species has occurred
C. A decrease in high-tolerance species has occurred
D. Phylogenetic diversity has occurred
E. The biodiversity of the pond has decreased
The answer to this question is E. The biodiversity of the pond has decreased
Explanation:
In ecology, an ecosystem can be affected by adjacent developments including human developments or even other ecosystems and this can lead to positive or negative consequences.
In this context, one example that shows the was an adverse effect is "The biodiversity of the pond has decreased" because the reduction in diversity represents a major thread for an ecosystem as this makes species more vulnerable to disappear. Also, this can be caused by factors such as pollution caused by human development or major predator of the adjacent ecosystem feeding on organisms in the main ecosystem. Besides this, in the first sample, there were multiple species and a reduction in the second sample shows the ecosystem was weakened.
Answer:
a.)
Operant conditioning -
It is a type of learning in which a person learns from consequences ( which may be positive or negative ) that follows person's behavior.
The procedures which encourage the person to do the things the same way he/ she used to do are called reinforcement,
The procedures which discourage the person to do the things the same way he/ she used to do are called punishment.
b.)
Strategies Jim and Kelly could use to encourage or discourage Ryan's behaviors :
Positive Reinforcement -
If Ryan eats without dropping off his food from the plate , it will be encouraging for him if Jim and Kelly appreciate him or buy gifts for him.
Negative Reinforcement -
If Ryan eats without dropping off his food from the plate , it will be encouraging for him if Jim and Kelly should avoid that behavior due to which Ryan is not learning the table manners.
For example - The scolding of Jim or Kelly when Ryan's is dropping off the food on the floor.
Positive Punishments -
If Ryan eats with dropping off his food from the plate , it will be encouraging for him if Jim and Kelly will add some consequences which Ryan will hate.
For example - If Ryan is eating with dropping off the food and Jim or Kelly yells at Ryan for his bad behavior.
Negative Punishments -
If Ryan eats with dropping off his food from the plate , it will be discouraging for him if Jim and Kelly removing any good thing in which Ryan is comfortable.
For example - Ryan's watching TV time reduced or taken away his toys.
The correct answer is C) reduce the economic hegemony of the global north.
The emergence of the BRICS (Brazil, Russia, India, China, South Africa) countries has the potential to most likely reduce the economic hegemony of the global north.
For many years the northern hemisphere nations such as Western Europe, the United States, and Canada have dominated trade and the economic world in general.
However, experts have considered that the advent of the BRICS (Brazil, Russia, India, China, South Africa) can represent an important block to seriously compete with those northern hemisphere powers due to the size of their markets and cheap labor.
Although those BRICS countries have interesting numbers in Macroeconomy, they still have very poor people that in Microeconomics that contrasts the Macroeconomy scenario.
