Match the stem cell types with the descriptions. -Pluripotent
-Multi potent (adult stem cells)
-Totipotent
1. Can differentiate into all body cell types of the embryo and the embryonic membranes.
2. Can only differentiate into cells of one tissue type.
3. A zygote is an example of one of these.
I
4. Can differentiate into any body cell type of the embryo, but not the embryonic membranes.
5. Are found in the blastocyst stage of embryonic development,
6. Primarily used for tissue repair, these are the least flexible of the stem cell types.

you know they are heterozygous for a trait because they have it as jj or jj.

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.
