The long-term and short-term carbon cycles are connected by the fact that some of the carbon contained in C6H12O6 (or other organic molecules) in plants is incorporated into sedimentary rocks or oil; carbon in sedimentary rock and oil is not immediately cycled back to the atmosphere. a. True
b. False

False

Explanation:

The carbon cycle is a process which involves the flow of carbon through all of living things and life forms on Earth. The carbon cycle span over two segments: long-term and short-term, allowing for regulation of atmospheric carbon dioxide.While the short term segment deals with Earth forms that are more 'fleeting' like water nd air, the long-term affects the rock which take centuries to process through completely.In the short-term reservoir, carbon is stored in the atmosphere, oceans and biosphere with the ocean containing the largest amount of carbon.  The biggest player and regulator of atmospheric carbon however is the ocean, not the biosphere. It is what links the long-term segment reserves to the short-term because carbon dioxide is removed from the atmosphere and converted to fossil fuels and rocks which are components of the long-term reserves.

I hope this explanation was clear and comprehensive.

Answer: abeexplanation:

1. the question asks the most appropriate, which seems to rule out "all of the above." your choice appears to be the correct one.

2. the protocol described is good for identifying correlation, but not cause and effect. for cause/effect, you need to devise a protocol that will assign the treatment (or not) to groups that have essentially the same "demographics" with respect to all the other variables. your choice regarding control group seems appropriate. random assignment of treatment (choice d) may be appropriate also. (i think you can argue that b and d are just different descriptions of the same method.)

3. d will randomize the birds, but may not guarantee there are 10 in each group. e will do both, so seems the better choice.

comment on question 2

based on the problem statement, it seems clear that confident, attentive drivers are more likely to use daytime running lights. so, the protocol might need to be devised in such a way that the lights would be turned on or off without the driver's knowledge. (an attentive driver will figure it out.) assigning a confident, attentive driver to a group required to drive without running lights might mess with his/her confidence and attentiveness. you don't want your experiment to do that. (nor do you want the experiment to subject a driver to greater risk of accident as a consequence of driving without running lights.) experiments involving human safety are always problematic.
