Answer:

B. decrease

Explanation:

 Base  dissociate to give  out  OH-  ions

 In the other hand ,when  water (H2O)   dissociate it  give out hydronium ions ( H3O+)    and OH- ions

when  base  is added to  water  more OH-   it  led  to  addition of more Oh- ions  hence  H3O+ decrease.

Graph y = -2x +3 and its inverse.
Gnesinka [82]
The graph of y = -2x + 3 is a straight line

Its slope is - 2

Its y-intercept is + 3

To draw the line you can use these two points (0,3) and (3/2 , 0)

This line does ont pass through the third quadrant. It comes downward from the second quadrant, touches the y-axis at y =3, continues on the rirst quadrant, touches the x-axis at x = 3/2, and contiues into the fourth quadrant.


Graph of its inverse

Exchange y and x in the given function and solve for the new y

x = - 2y + 3 => y = - x/2 + 3/2

It is also a straight line;
Its slope is -1/2
Its y-intercept is 3/2

It is also in the second, first and fourth quadrant

Use these two points to draw the line (0,3/2) and (3,0).

You do not need to know to draw this, but the inverse of a function is its reflection through the line y =x.

The question is stated incorrectly. The correct question is as follows;

The site of intercellular communication between a neuron and another cell is the.

Answer:

Synapse.

Explanation:

Neurons have dendrites, cell body and axons. Millions of neurons are present in the nervous system. Different types of neuron are sensory neuron, motor neuron and interneuron.

Synapse may be defined as the gap between the two consecutive neurons. The junction between the two neurons that helps in the intercellular communication. The neurotransmitters are diffused directly and transmit information through these synapse.

Thus, the correct answer is synapse.
