Explanation:

The "Texas oil boom" is also known as the "gusher age." It occurred in the early 20th century. This happened when a huge supply of oil reserve was discovered near Beaumont, Texas. This led to rapid development and industrialization in the area, including the field of education.

Upon the creation of the "Santa Rita oil well," the University of Texas (a public research university in Austin) and the Texas A&M ( a public research university in College Station, Texas) obtained revenue which helped fund for their growth. This made the two universities the wealthiest among many universities in the country.

The barrier functions to regulate the chemical composition of the extracellular fluid surrounding the brain cells.

Explanation:

Blood-brain barrier

It is a very selective semipermeable membrane , hence allow some specific substance to pass via it . This barrier separates the  extracellular fluid in the central nervous system  and the circulating blood from the brain .

The barrier is composed of the endothelial cells .

Passive diffusion is shown in this system , and allows molecules like the water , glucose , amino acid to pass .

It regulates the chemical composition of the fluid of brain cell .
