Where do light-dependent reactions occur?
a. the stroma
b. the thylakoids
c. chlorophyll
d. ferredoxin

b. the thylakoids  

Explanation:

Chlorophylls are located in chloroplasts, which organelle is the continent of photosynthesis, ie, where the two important reactions occur: photochemistry, on the thylakoid membranes and biochemistry, in the chloroplast stroma.

The pigments involved in photosynthesis are chlorophylls a and b, carotenoids and phycobilins. Chlorophyll b, carotenoids, and phycobilins constitute the so-called accessory pigments. The energy absorbed by the pigments is transferred to well-defined sites located on the thylakoids membranes, the so-called reaction centers.

common management practices in dairy and poultry farming are: (i) proper shelter facilities and their regular cleaning. (ii) some basic hygienic conditions such as clean water, nutritious food, etc. (iii) animals are kept in spacious, airy, and ventilated place.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

e) all of the above
