In the desert, saguaro cacti, owls, horned lizards, and fire ants all share the same space. which example can be considered a population? a. all cacti in the same areab. the lizards and the antsc. all plants in the same aread. all species in the same area

all cacti in the area.

Explanation:

Population is the total number of organisms of the same specie present in an given area.

Based on the given area (desert), all the cacti, best describes population.

Note that whenever different species (lizards, owl etc) are considered like in options B, C and D, you are referring to a community

Thus, all cacti in the area are considered as population.

the answer is "a.) well–developed vascular system."

explanation:

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.
