Which statement/s show/s the relationship between the processes of photosynthesis? I. Light energy is harnessed in Photosystems, both of which are present in the thylakoid membranes of mitochondria.
II. The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process.
III. The light-independent molecules depend on the energy carrier molecules, ATP and NADPH, to drive the construction of new carbohydrate molecules.
IV. Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and RubP.

Select one:

a. I only
b. II only
c. II and III
d. III and IV

answer; i believe the correct answer is ( proteins );

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression

explanation:

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
