Answer:

The correct option is B: the expression of NMDA receptors is more abundant in hippocampal than cortical neurons

Explanation:

Global Ischemia is known to cause damage to neurons in distinct areas of the brain. The expression of NMDA, a pattern of selective vulnerability capable of being reproduced is usually seen in the dorsal hippocampal of animals, especially rodents, where the neurons in the CA1 area is mainly affected. Thus, this explains why the hippocampal is the area well faced with a high risk of vulnerability during global ischemia.

According to the kinetic molecular theory, temperature is directly proportional to _____.
Elena-2011 [213]

According to the, Kinetic Molecular theory, temperature is directly proportional to average Kinetic energy of gas particle

Explanation:  

At the level of molecule  kinetic energy model helps to understand the gaseous physical properties. The kinetic energy model is based on several concepts.

In the constant random  motion gases are made of molecules or atoms.

The particles of gases are are constantly colliding with each other.

The particles of gas are small and the complete volume taken by gaseous molecules are negligible in comparison to complete volume of container.

Between the gas particle their is no repulsion or attraction.

Gas particles average kinetic energy is proportional to the fixed  temperature of the gas, and all gas at the equivalent temperature have the equivalent average kinetic energy.
