Answer:
The correct answer is: A) the Calvin Cycle alone.
Explanation:
These reactions happen in cells capable of photosynthesis.
The only out of these reactions that require CO2 to take place is the Calvin Cycle. The Calvin Cycle is a series of biochemical processes that occur in the chloroplasts during photosynthesis. <u>The Calvin Cycle uses carbon dioxide (CO2) and water to produce glucose</u>, which will give energy to the cells.
The light reactions occur during photosynthesis in the presence of light and involving photophosphorylation. The light reaction does not make use of CO2, as it takes solar energy and converts it into NADPH and ATP.
D) orbit the nucleus like the planets orbit the sun.
this idea was first proposed in the rutherford model:)
A leaf is made up of many layers and is surrounded by two. Upper epidermis, mesophyll, bundle sheath, vein, mesophyll, lower epidermis, and guard cells.
