Muchos tipos diferentes de mutaciones pueden ocurrir dentro del cuerpo. Un individuo experimenta una mutación que cambia
una base en una cadena de ARNt, pero durante la traducción la cadena de ARNt todavía crea la misma proteína. ¿Qué tipo
de mutación es responsable del cambio en la base de tRNA?

tissue

explanation:

it is actually formed by geoup of cells which is tissue

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.
