<span>The correct answer is "Absorption of rainfall by soil."
The hyrdosphere refers to all water on the earth's surface. The geosphere, in this context, refers to the solid parts of the earth (rocks, sand, etc.) Since rain is part of the hydrosphere and soil is part of the geosphere, rain soaking into the soil would be an interaction between the two. The other choices deal with changes in the hyrdrosphere, but there is no interaction with the geosphere.</span>
<span>1. A hydrogen fuel cell is more efficient than a combustion reaction because very little of the released energy is released as HEAT.
We need more energy emit as light and less heat. Lesser the heat more the efficiency.
2. </span>when used at home a fuel-cell illuminates the need for <span>an electrical grid</span> because the cell is portable.
As said, it is portable.
Answer:
The correct answer is NADPH.
Photo-system I absorbs maximum photons at the wavelength of 700 nm.
It uses this energy to transfer the electron (received from photo-system II) to NADP⁺ to reduce it to NADPH.
Once, the reaction centre of PS I or P₇₀₀ gets excited, it transfer the high energy electron to the ferrodoxin (Fd) via cluster of iron and sulphur protein (4Fe-4S).
Reduced ferrodoxin then transfer the electron to NADP⁺ to reduce it to NADPH with the help of flavoprotein (ferrodoxin-NADP⁺ reductase).
NADPH is then used in Calvin cycle or light-independent phase of the photosynthesis in order to fix carbon to produce sugar or food.
The freshwater biome is made up of any of body of water that is made of freshwater such as lakes, ponds, streams, and rivers. They cover roughly 20% of the Earth and are in various locations spread out all over the world. Most freshwater biomes consist of moving water and contain many types of fish
