The light reactions of photosynthesis supply the Calvin cycle with (d) ATP and NADPH.
Light reactions are photochemical reactions which are directly driven by light. They are responsible for the synthesis of ATP as well as NADPH.
Light reactions take place in the membranous system that is present within the chloroplasts. The membrane system consists of grana, the stromal lamellae and the matrix stroma.
The products of light reaction include ATP, NADPH as well as O₂. However, ATP as well as NADPH are used in driving the processes which result in the production of sugars, whereas O₂ diffuses out of the chloroplast.

Answer:
option B
Explanation:
igneous rocks are the rocks which are formed by the cooling of molten magma cooling can be on the surface or below the earth surface.
sedimentary surface is the rocks which are formed by the weathering or some chemical action upon the rock due to the passage of time.
metamorphic rocks are those rocks which are formed due to the high pressure and temperature acted on the rocks.
so, the best answer will be sedimentary rock
hence, the correct answer is option B

Answer:
The correct answer is - option C. alligators; their tails dig holes that hold water during times of drought, and this water is used as a source for drinking water by many species.
Explanation:
Beavers are keystone species as they help other species to get habitat and also help plants to grow by the holes or dams they make. Kudzu is a keystone species of an ornamental plant which lowers the soil erosion in their abundance.
Red cocaded woodpecker is a keystone species as they create pits in the pine trees that are helpful for other species to live.
Alligators also keystone species but not for digging holes and hold water but the influencing the prey and maintaining the animals in the ecosystem.
