Answer:

Explanation:
Mechanical advantage is given by the ratio of output force by input force.
= Output force = 
= Input force = 
So,

The mechanical advantage of the pulley's is
.
The correct answer is (a).
Both L-D and L-IND reactions take place in the chloroplast of the cell but in different parts or locations. L-D reactions take place in the chloroplast thylakoids while L-IND reactions take place in the chloroplast stroma.
Chloroplasts are chlorophyll- filled organelles mostly found in the leaves of green plants. Chloroplasts are surrounded by a double membrane called the thykaloid membrane that forms long folds within the organelle. In electron micrographs, the thykaloid membranes look like stacked coins. Chlorophyll is located within the thykaloid membranes.
Between the thykaloid membrane and the chloroplast membrane is a space. This space is what is called the stroma.
