1. Amino acid is to protien as A. amino acid is to liquid
B. dna is to rna
C. sugar is to fat
D simple sugar is to cellulose

D

Explanation: Cellulose is made up of simple sugars, the same way protein is made up of Amino acids

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

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.
