Answer:
C. More young children live in Country 1 than in the other countries.
Explanation:
The described graph shows that more young children live in Country 1 than in the other countries. This is clearly stated in the first paragraph: <em>This is the greatest percentage of any 4-year age span in all three countries.</em> This automatically means that options B and D are incorrect.
Option A is the second-best one. However, the fact that there are more young children in Country 1 doesn't necessarily mean that their death rate is lower. It could be, but correlation doesn't equal causation. There are more young children probably because the younger population is more present in that country and more children are born.
This is why option C is the correct one.
To determine what the base sequence for the complementary strand, would be simply remember the base pairing or nitrogenous base pairing rules, for which nitrogen containing base hydrogen bonds or complementary base pairs with another.
A = T
G = C
So the complementary strand would be :
GCATCC.
Answer: I believe the right answer is B) atmospheric nitrogen→bacteria→plants→animals. I'm pretty sure!
