Answer:
The statement is False
Explanation:
Osmotic pressure is created by the movement of water across the semi-permeable membrane. In osmosis water moves from an area which is having low solute concentration to the area which is having high solute concentration.
So in osmosis, the movement of water takes place not molecules. This pressure is caused by differences in solute concentration across the plasma membrane and water moves to high concentration to equalize the pressure. Therefore the statement is wrong.
Answer:
The correct option is a. "increased cortical mass, increased numbers of neurons, increased synaptic connections, increased neurotransmitter amounts, and increased myelination.
"
Explanation:
Rodents that have been raised in enriched environments were found to have thicker cerebral cortex containing approximately 25% more synapses in a study conducted by Mark Richard Rosenzweig. This increase in <em>synapses</em> implies in an increase in <em>neurons</em> and <em>neurotransmitters</em>, which also indicates an increase in <em>myelination</em>.
