Answer:
Cohesion and adhesion of water molecules
Explanation:
Cohesion has to do with the ability of water to adhere together .
The cohesive properties of water which is occasioned by hydrogen bonding between adjacent water molecules allow the column of water to move up through the plant irrespective of the force of gravity as water molecules are evaporating at the leaf surface.
The adhesive properties of water, which means, the attraction between the water molecule and the xylem wall also ensure continuity in the movement of the water column in the xylem.
Hence the cohesive and adhesive properties of water molecules are important for transpiration to occur.
“This transient switch in membrane potential is the action potential. The cycle of depolarization and repolarization is extremely rapid, taking only about 2 milliseconds (0.002 seconds) and thus allows neurons to fire action potentials in rapid bursts, a common feature in neuronal communication.”
Well it can be hard to identify if rain is acidic or not
Answer:
Because every zone of the ocean has the combination of the organisms living there that are adapted to the light, pressure, and temperatures. About ¾ of the ocean is very dark and cold, and very deep.
Explanation:
The first zone is the sunlight zone or the zone where the sunlight can enter. The depth goes to 200 meters and up t this depth the process of photosynthesis is possible.
Under 200 meters is the second zone of the ocean, called the twilight zone, where the sun almost doesn’t get. The temperature in this zone is changing depending on the wind, but the most often the temperature is very low.
Under 1000 meters, there is the third zone called deep ocean, very dark and cold.
