Trace the path of oxygen, water, carbon dioxide, and glucose in the transparency

The correct answer is:  

During transparency in photosynthesis, we first have oxygen and water that enter the cell through the cell membrane. Once they passed the membrane, in the cell starts the production of carbon dioxide and glucose. After that, carbon dioxide is goes to the Calvin cycle, so, in the end, energy is created in form of a glucose.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
