Answer:
<em>B. Female Merrick sea turtles begin returning to Bakerâs Beach to lay their eggs when they are ten years old.</em>
Explanation:
Firstly, There was an oil spill five years ago-no eggs hatched.
Now, the number of females coming back to the lay eggs has increased somewhat since the last five years.
The theory is that a period of 5 years is sufficient to assess effect on population.
If the breeding cycle has been found to be ten years long, then the impact of the oil spill on the population (as observed by the number of females returning to lay eggs) will only be perceived in the 10th year.
It undermines the argument that the oil spills don't impact the public.

Answer:
See explanation
Explanation:
The melting point range of a pure compound is about 1-2ºC of the expected melting point. An impure solid melts within a range that is both larger than that of the pure substance (>1ºC) and begin at a lower temperature because impurities decrease the meting point. A melting range of 5º or more indicates that a compound is impure.
Since the melting points of A and B are estimated at 133 o C, the melting point range for each pure substance must be slightly different from each other. The melting point of the unknown is measured and its range is compared with the melting point ranges of pure A and B then decision can now be made about the identity of the unknown solid.
Answer:
Try looking back at what to do and reading back through it to understand it.
Explanation:
H2O means each molecule of water consists one oxygen atom chemically bonded to two hydrogen atoms. Which means that WATER is a COMPOUND.
