a) Osmotic pressure b) Water potential
ClOsmosis
d) Plasmolysis
Solve problem

Answer 1

Answer:

A high specific heat of a substance means that a large amount of heat is required to raise the temperature of the substance. Water is the substance with the second highest known specific heat capacity. at 4186 J/ (kg*K)

Answer 2

The capacity of a living system to lose water is (b) Water potential.

Explanation:

• The energy required is water potential as per the quantity of water transport an infinitesimal quantity of water from the reference pool sample with pure water.
• In this we can understand that means compare the water in a soil sample to water in a drinking glass.
• Water potential is the difference between free energy of water molecules in a pure solvent and free energy of water molecules in a solution.
• Water potential is the potential energy of the water in a device relative to pure water as both temperature and pressure are preserved in the same way.
• This can also be defined as a measure of how free molecules of water may move in a given environment or device.
• Living systems are open self organizing life forms that interact with their environment.
• These systems are maintained by flows of information, energy and matter. Some scientists have proposed in the last few decades that a general living systems theory is required to explain the nature of life.
• Water potential is the potential energy of water per unit volume relative to pure water in reference conditions.
• For example the addition of solutes lowers the potential (negative vector), while an increase in pressure increases the potential (positive vector).
