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.
<span>B. you are breaking the law.
If you are INVOLVED in the accident, & you do not stop, it is commonly known as a 'hit-and-run', and it will give you a mark, as well as you having a chance of your DL suspended.
hope this helps</span>
Answer:
The results only apply to the individual or group being studied.
Explanation:
Case study is one of the methods followed for researches and observations. It helps in an advanced and detailed method of getting along with a particular topic. In case studies, the topic or the subject is studied extensively and observations are made through them. Case studies involve a detailed study of individual or group whose results are not in a general form. The results are applied to the specific individual or the group.
Neurobiological functions, structures, activity, and biological needs and functions
Explanation:
By graphing cigarettes per day on one axis, and anxiety test score on the other axis, we see a strong positive correlation between the two.
One explanation is that smoking causes anxiety. Another explanation is that people with more anxiety are more likely to smoke.
