In plant physiology, the 'Osmotic pressure' is the pressure that must be applied to a solution to prevent the inward flow of water across a semipermeable membrane. It is directly proportional to the:
A. Volume of the solution
B. Size of the solute molecules
C. Concentration of solute particles
D. Temperature only
Answer: Option C
Solution (By JKSSB Mock Tests)
Osmotic pressure (OP) is a colligative property of a solution, meaning it depends on the number of solute particles dissolved in a given volume of solvent, not on the nature or size of the particles. It is defined as the hydrostatic pressure that must be applied to a solution to prevent the net flow of water (osmosis) into the solution across a semipermeable membrane. According to the van't Hoff equation, osmotic pressure is directly proportional to the molar concentration of solute particles and the absolute temperature. The more concentrated the solution, the higher its osmotic pressure.
Explanation:
Acetylcholine is an excitatory neurotransmitter at neuromuscular junctions and many CNS synapses. GABA and glycine are generally inhibitory in the CNS. Serotonin modulates mood but can have inhibitory or excitatory effects depending on receptors. Neurotransmitters are chemical messengers released from synaptic vesicles into the synaptic cleft to bind to postsynaptic receptors.
Explanation:
Transduction is the transfer of bacterial DNA by a bacteriophage (virus). Transformation is uptake of free DNA, conjugation is direct transfer via pilus, binary fission is reproduction.
Explanation:
The liver is the primary site of glycogen storage and releases glucose into the blood between meals (glycogenolysis) to maintain blood sugar. Muscles also store glycogen but for local use. The pancreas regulates blood sugar via insulin/glucagon, spleen stores blood and recycles iron, kidneys excrete waste.
