A forest has two groups of plants that appear to be very similar both phenotypically and genotypically. The major difference is

that one plant group releases its pollen in February, while the other group releases its pollen in April. Design a plan for collecting the data needed to determine whether the plants are members of one population with great diversity or members of two separate species.
be sure to include:

-the variables you plan to use
-a detailed description of the experiment
-how data would be collected
-how data would be analyzed

The basics would be that you'd need to find out if they could exchange genetic information. If not, they couldn't be considered part of one species. Set-up 2 artificial environments so both groups would produce pollen at the same time. Fertilise both plants with the other's pollen. Then fertilise the plants with pollen from their own group. 
Count the number of offspring each plant produces. 
If the plants which were fertilised by the opposite group produce offspring, they are of the same species. You can then take this further if they are of the same species by analysing if there is any difference between the number (and health) of offspring produced by the crossed progeny and by the pure progeny. You'd have to take into account that some of them would want to grow at different times, so a study of the progeny from their first sprout until death (whilst emulating the seasons in your ideal controlled environment). Their success could then be compared to that of the pure-bred individuals. 
Make sure to repeat this a few times, or have a number of plants to make sure your results are accurate. 
Or if you couldn't do the controlled environment thing, just keep some pollen one year and use it to fertilise the other group. 
I'd also put a hypothesis in there somewhere too. 
The independent variable would be the number of plants pollinated. The dependant variable would be the number of progeny (offspring) produced.

What statement most directly demonstrates a way that the geosphere is involved in the nitrogen cycle
Ulleksa [173]

B. bacteria that convert ammonia into nitrites and nitrates are found in the soil  

This statement best demonstrates a way that the geo-sphere is involved in the nitrogen cycle.

A nitrogen cycle is defined as the movement of nitrogen between the atmosphere, biosphere, and geo-sphere in different forms. Ammonia is converted to nitrates by nitrifying bacteria in the soil. Then the plants absorb these nitrates from the soil and use these to build up proteins.
