The correct option is C.
The recombination of atoms to form newer molecules is called chemical change. Tarnishing is a chemical change that occur when a metal lose luster as a result of exposure to moisture and water which results in a thing layer of corrosion which forms over the metal.<span />
Answer:
Biotic factors include plants, animals, and microbes; important abiotic factors include the amount of sunlight in the ecosystem, the amount of oxygen and nutrients dissolved in the water, proximity to land, depth, and temperature. Sunlight is one the most important abiotic factors for marine ecosystems.
The mesosphere is the coldest layer of the atmosphere.
Hope that helped you.
initially as temperature increases rate of photosynthesis increases, but after reaching on climax, due to scarcity of water, it starts to decrease
Answer:
Water has a high Cohesion because of Hydrogen bonding. This is important as transport of water in the Xylem in plants relies on water being pulled up. Cohesion also gives the water a high surface tension, allowing small organisms, such as Pond Skaters, to walk along it.
Explanation:
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.
Plants obtain the hydrogen they need from water molecules. Don't try to feed your plant hydrogen gas -- your plant wouldn't know what to do with it if you did. As long as they have water, plants can readily obtain all the hydrogen they need. :)
