1.	Why is the colour of a leaf kept in the dark frequently yellow, or pale green? Which pigment do you think is more stable?
Answer» Carotein is much more stable as compared to chlorophyll and does not breakdown easily. Therefore, the leaf appears yellow or pale green due to stable carotenoids whereas the green chlorphyll breakdown if the leaf is kept in dark.

Make corrections wherever you find mistake in spellings/words in the following paragraphs :- A. When fats are used in respiration, the RQ is more than unity because fats contain more `O_(2)` and require relatively less amount of `O_(2)` for oxidation. B.
