Water is essential for life. its special properties make water the single most important molecule in plant life. which of the following properties of water enable it to move from the roots to the leaves of plants?
a: water exhibits cohesive behavior.

b: water expands as it freezes.

c: water is able to moderate temperature.

d: water is an excellent solvent.

A, Water exhibits cohesive behaviour

Explanation:

This is because they are polar molecules so they attract.

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.
