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.
The functional group of <span>salicylic acid forms a complex with fe if colored reaction observed with the iron 3 chloride test would be the phenol group of the compound. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
Explanation:
2 C(s) + 3 H2(g) = C2H6(g)
The common greenhouse gas containing only hydrogen and oxygen is H2O, this is water vapor.
The common greenhouse gases are water vapor, carbon dioxide, methane, nitrous oxide and ozone.
The composition (chemical formula) of those gases are:
Water vapor: H2O
Carbon dioxide: CO2
Methane: CH4
Nitrous oxide: NO
Ozone: O3.
As you see the only one of those that contains only hydrogen and oxygen is H2O, water vapor.
