Which of the following is not true? A. There are more interneurons than motor neurons in the human nervous system B. The amygdala is closely-linked with fear and aggression C. The hypothalamus is essential in maintaining homeostasis D. The cerebellum (AKA the "little brain") helps with the coordination of voluntary movement E. Dysfunction of acetylcholine (ACh) is associated with Alzheimer's disease F. The parasympathetic nervous system is devoted to voluntary control of skeletal muscles G. The term for the "meeting point" between neurons - the synapse - was coined by Sir Charles Sherrington

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

a metamorphic rock would be formed.

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
