What is self pollination

This is the pollination of flower by pollen grains from the same flower on the same plant.

Explanation:            OR:

This is also when pollen from the same plant arrives at the stigma of a flower or at the OVULE.

Many plants that can be self pollinating can also be cross pollinating.

Examples of self pollinating plants are: wheat, tomatoes, barley, e.t.c.

This is also the transfer of pollen from the anther to the stigma of the same flower or the flower of the plant with the same clone.

Hope all these helps.

it is either c or d and i know for sure it is not a or b

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.
