The production of oxygen from a reactant in a chemical reaction is shown in the graph below. The graph shows the volume of oxygen produced as a function of the amount of reactant consumed. If the trend continues, how much oxygen will be produced when 25 g of the reactant is consumed?
A. 3.0 ml
B. 4.0 ml
C. 5.0 ml
D. 1.5 ml

it’s C ; 5.0ml

Explanation: because it just is . it’s a pattern it basically . all you have to do is go right from the original red dot and than up one . I hope I explained it right .

several tissues working together form an organ, and several organs together make up an organisms.

the group of cell that carries out special jobs are 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.
