Prepare for NEET with Botany-specific practice questions. Covering all major Botany chapters, this is perfect for your NEET Biology needs.
Imagine a U-shaped tube with a selectively permeable membrane separating two solutions. Side A contains a 0.2M sucrose solution, and Side B contains a 0.1M NaCl solution. Initially, the levels are equal. Considering the dissociation of NaCl and the non-penetrating nature of sucrose and NaCl, which side will have a higher level at equilibrium?
Side A
Side B
The levels will remain equal
The membrane will rupture
Select the false statement I. Living process is a constant effort to prevent falling into equilibrium II. Energy can enter and leave a cell III. Matter can enter and leave a cell IV. Metabolic pathways are interlinked
Only I
Only IV
I and IV
Only II
When a metabolic disequilibrium is in effect, then only cells continue to function
How do cells avoid reaching metabolic equilibrium?
Only cells that have reached metabolic equilibrium continue to function.
Only cells that avoid reaching metabolic equilibrium continue to function.
Metabolic equilibrium is essential for cell function.
Cells function optimally at metabolic equilibrium.
When a metabolic disequilibrium is in effect, then only cells continue to function
How do cells avoid reaching metabolic equilibrium?
Cells constantly exchange matter and energy with their surroundings.
Cells exist in a closed system, preventing interaction with the external environment.
Cells utilize feedback inhibition to slow down metabolic reactions, preventing equilibrium.
Cells maintain a static internal environment, independent of external influences.
Choose the correct options
E + S → ES → E + P →EP
E + S ⇌ ES → E - P → E + P
E + S → ES ⇌ E - P → E + P
E + S ⇌ ES ⇌ E - P ⇌E+P
Why living state cannot afford to reach equilibrium?
Due to insufficiency of biomolecules
To remain active all the time
To save the energy
None of the above
Passive absorption of mineral salts is not dependent on

Ionic exchange
The rate if diffusion is dependent upon the permeability of the medium, it however

Does influence the final equilibrium of diffusion
Does not influence the final equilibrium of diffusion
None of the above
The term ‘homeostasis’ in an ecosystem refers to
