What is the ultimate result of benzodiazepines in the brain?
a. decreased activity of gaba neurons
b. increased activity of gaba neurons
c. gaba is unable to bind to receptors because they are filled with benzodiazepines.

b. Increased activity of GABA neurons is the correct answer.

Explanation:

The ultimate result of benzodiazepines in the brain is it Increased activity of GABA neurons.

Benzodiazepines work by enhancing the impact of a brain chemical called gamma-aminobutyric acid.

Benzodiazepines work by reducing the nerve activity within the brain and rest of a central nervous system.

When GABA attach to a protein present in your brain called GABA receptor it produces a calming effect and it helps with a feeling of stress, fear, and anxiety and also prevents seizures.

centre = (- 2, 3 ), radius = 3

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Given

x² + 4x + y² - 6y = - 4

Using the method of completing the square.

add ( half the coefficient of the x/ y terms )² to both sides

x² + 2(2)x + 4 + y² + 2(- 3)y + 9 = - 4 + 4 + 9, that is

(x + 2)² + (y - 3)² = 9 ← in standard form

with centre = (- 2, 3 ) and r = = 3
