Answer:
DNA is a genetic molecule
Explanation:
Though both the nucleic acids can act as genetic material, DNA is much more preferred. DNA is stable both chemically and structurally which make it well-built genetic material.

Water is the main constituent on the earth surface. It is important for all living beings to survive. It is a transparent, odourless, colourless chemical substance. Water has vital role in atmosphere. It undergoes several cycles. In water cycle, water from rivers, lakes and streams enters the atmosphere through Evaporation. In evaporation the element or the compound in it's liquid state changes to gaseous state below the temperature at which the it boils. This is due to the high temperature. Due to high temperature the water from different water bodies enters the atmosphere in the form of vapours. In the carbon cycle, water exits the pore of leaves in plants by a process called as transpiration. Transpiration is a process by which the moisture is transferred from roots to the outside of the leaf whic
Therefore, In water cycle, water from rivers, lakes and streams enters the atmosphere through vaporisation. in the carbon cycle, water exits the pore of leaves in plants by a process called as transpiration. In nitrogen cycle, the water as well as dead organism moves nitrogen from the atmosphere into the soil.
Answer:
C) The Calvin cycle requires ATP and NADPH, which require sunlight to be produced
Explanation:
The light-dependent phase of photosynthesis includes the photolysis of water molecules. The released electrons are passed to PSII to PSI via electron carriers and finally to NADP+ to reduce it into NADPH.
Transfer of electrons via electron carriers also generates the proton concentration gradient which in turn drives ATP synthesis. ATP and NADPH formed during light reactions are used in the Calvin cycle as an energy source and electron donor respectively.
Hence, to continue, the Calvin cycle requires the synthesis of ATP and NADPH in the presence of light.
Can start a fire( rubbing to rocks together) and friction is used when you hit the brakes on a car( the pad pushes down on the tire). Good luck!
