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.
Different populations will have different viewpoints on the boundaries (most likely bad viewpoints)
Answer:
1) A progressive tax is defined as a tax whose rate increases as the payer's income increases. That is, individuals who earn high incomes have a greater proportion of their incomes taken to pay the tax. A regressive tax, on the other hand, is one whose rate increases as the payer's income decreases.
2) The government has few choices of action to protect its domestic industries. It can implement trade barriers as for example the import quotas and tariffs on imported goods. The two are both lower the consumer's welfare. The tariffs usually would increase the prices of imported goods, therefore consumers would choose the domestic good, meanwhile the import quotas decrease the supply of imports and consumers are obligated to purchase domestic goods of prices higher than the imported goods.
3) Public good is a commodity or service that is provided without profit to all members of a society while private goods is a product that must be purchased to be consumed. There are few reasons for which the government's action is necessary to ensure the provision of public goods such as the very efficiency of this action, the goods and services might be beneficial not only for the purchaser, but other individuals, the value of the good and service becomes greater than what an individual can pay, and also it boosts the economic equity.
4) The government applies equal taxes and regulations to protect the competition. It needs to apply those in order to prevent the creation of monopoly.
5) The censorship has at its core to prevent or to minimalism one's knowledge or access to a product, therefore as a consequence it can increase the prices and have negative consequences on companies and economy in general.
