If the pressure in the habitat is increased, then the anglerfish will have a (higher/lower) health rating.

The anglerfish will exhibit healthy health rating.  

The anglerfish refers to a bony fish named after its featured mode of predation. The species of the fish occur globally, most of the anglerfish are benthic, that is, they dwell close to the floor of the sea. At the depth of deep-sea, the pressure is very high, however, various creatures exhibit no issue living there.  

In the absence of gas-filled spaces like swim bladder or lungs, the species in the great deep sea are less influenced by the pressure than one can think. Though the species adapted to such pressure conditions, when being brought to the surface of the sea may encounter with certain metabolic issues. Thus, increasing the pressure will cause no harm to the health of anglerfish.  

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.
