Which the following statement is FALSE?

a. Relative water content is not a very sensitive index because leaves can show strong responses to <2% change in RWC
b. Relative water content is not a very sensitive index because it gives no information about the forces for water movement
c. Relative water content is equal the ratio of the mass of water in a given leaf over the mass of water when that leaf was fully saturated
d. Relative water content is equal the ratio of the mass of water in a dry leaf over the mass of water when that leaf was fully saturated

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
