Because of underdeveloped lungs the frog has to breathe through moist skin. Therefore for exchange of gases the skin is thin and moist
The energy from sunlight comes in the form of photons, and this energy is used in the light dependent reactions of photosynthesis. The first function carried out by the photons in energizing electrons in the chlorophyll. The energized electron travels through the electron transport chain and subsequent steps are carried out to utilize this energy to form ATP.

10) A
Answer:B
Explanation:
The first stage of photosynthesis is the light reaction which occur in the thylakoid membrane of the chloroplast. Solar energy of light captured by chlorophylls, and is used to produce high-energy electrons of which in a series of reactions produces ATP and NADPH.
In the dark reaction of photosynthesis the ATP and NADPH are used to reduce CO2 to produce sugar
