Answer:
Cyanophtya
Explanation:
Cyanobacteria also known as Cyanophyta are responsible for fixing nitogen and raising phosphorus level through mineralization they are also called blu-green-algae. They commonly obtain their energy from 'oxygenic' photosynthesis.
Answer:
1. Solute potential= -2.43 bars
2. Solution to root tissue
Explanation:
The solute potential is the potential or concentration gradient exerted by the solute in a solution.
The mathematical expression of the solute potential is
= -iRCT, where i= ionization of molecule
C- concentration of a molecule
R - pressure constant (0.0831)
T- Temperature (kelvin)
According to the given question,
i=1 ( sucrose is non-polar)
R= 0.0831
T= 273+ 20= 293
C= 0.1
Putting the values in -iRCT
we will have solute potential = -2.43 bars (high water potential)
Since the potential in root tissue is -3.3 bars. (low water potential)
We know that water moves from high water potential to low water potential and the water will move from the solution to the root tissue that is from -2.43 bars to -3.3 bars
Gravity is the force of attraction between two objects, and Earth's gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. ... Gravity pulls denser air and water downward, forcing less dense air and water to move upward.
