The answer would be A because
D does not solve the
Problem because the sewage is still there
C just moves the sewage to a different area still causing pollution
B removes the organic material but the rest is still there
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: i think the answer is D
Answer:
= 471.239 cubic feet
Explanation:
Given the above question and attached drawing
Hence, to find the total Volume of the tank, represented as (V)
= 9∫0 [ 4 √ 625÷ 9]² * dy = 150 π ≈ 471.239 cubic feet
OR
Volume = 2 π 5∫0 x * [9 - 9÷625x⁴] * dx = 471.239 cubic feet.
Therefore the total volume of the oil tank is 471.239, while the units of measure is in Cubic feet.
Bonds are interest-bearing assets and stocks do not.
Option - D
<u>Explanation:</u>
Stocks are an money invested in exchange of company shares (equity investment) that depicts part of ownership in a company and entitles the stock holder to a part of that company's assets and earnings. Stocks do not offer interest rates instead pays dividends and there will not be any fixed returns.
Bonds are interest-bearing or debt security, by which the lender is due to be reimbursed to the holders a debt (based on the negotiated bond terms) and is supposed to pay them interest or to repay principal amount at the maturity date. Zero-coupon bond pays both principal and imputed interest at maturity.
