The choices can be found elsewhere and as follows:
a. Increased temperature and pressure
b. Melting and crystallization
<span>c. Exposure and weathering </span>
<span>d. All of the above
</span>
I believe the correct answer is option C. It would be Exposure and weathering that would cause an igneous rock to become soil. <span>Weathering breaks rock down into small particles which are carried away by erosion and deposited somewhere, sometimes creating very verdant soils. </span>

Hope this helps!!!
I believe it is “animals and plants caanot directly use all the nitrogen found in our atmosphere”
Answer:
Active transport
Explanation:
The molecules are moving from a low concentration to a high concentration across a cell membrane via a protein. ATP is used in this reaction.
We know it cannot be diffusion, facilitated diffusion, passive transport, or osmosis, because these are all passive processes. In the picture, the molecules are moving against their concentration gradient and uses energy.
It cannot be endocytosis or exocytosis, as there are no vesicles.
Active transport is the movement of molecules from a low concentration to a high concentration across a cell membrane against their concentration gradient. ATP is used to supply the energy for this process.
