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:
The magnetic field of the earth was discovered by Carl Friedrich Gauss in 1835.
Answer:
166.67%
Explanation:
The computation of the percentage increase in grain production for the period 1950-1955 is shown below:
= (Year 1995 grain production - Year 1950 grain production) ÷ ( Year 1950 grain production)
= (1,600 million tons - 600 million tons) ÷ (600 million tons)
= 1,000 million tons ÷ 600 million tons
= 166.67%
Hence the increase in percentage is 166.67%
Answer and Explanation:
Notes: Slavery allows it to be so harmful that it changes even the most kind people, making them mean. Education empowers the oppressed. Education is a powerful weapon for blacks. Deprivation can be used as an incentive. Nobody liked to be called an oppressor, even though it was.
I decided to take notes on the most important themes exposed by Douglass. These themes were discovered by reading chapter 6 and by interpreting why Douglass decided to include these moments of his life in his narrative.
The first theme that I noticed is that slavery was widespread and prejudicial to everyone, even for the arms. Slavery placed cruelty in the hearts of white people and made them lose their kindness and kindness by becoming cruel and unworthy. I also noticed that white people were very afraid to allow blacks to have access to education. This is because education allowed the critical thinking that would give blacks the power to fight against the system that oppressed them.
Douglass was deprived of studying, but this deprivation motivated him to strive and receive an education that would make big differences in his life. Last but not least, we can see that the whites knew that the violence of slavery was incorrect, since they did not want them to know that they were extremely violent and oppressive to the slaves they owned.
The author uses several rhetorical strategies that range from personal statements, which increase our empathy for him, to logical and correct statements that show us how that whole slave system worked and how it was manipulated to last. This all causes an extension of what we know about slavery.
Activities such as a bonfire we do for fun we’re necessities in the past as they had no other way to keep warm or to heat food whilst we today just do it for fun to roast marshmallows and to get outside for a fun activity. But back then this was necessary for survival and the discovery of fire was one of the most influential things back in the past.
