Which statement is correct regarding internal or external respiration? a. internal respiration occurs in the alveoli b. internal respiration occurs in the body’s tissues c. external respiration occurs in the body’s tissues d. external respiration involves the exchange of gases with the internal environment e. none of the statements are correct

option B

Internal respiration occurs in the body's tissues.

Explanation:

Internal respiration occurs in the body's tissue and it is the exchange of gas between the blood and cells or within the internal environment.

External respiration is the exchange of gas with the external environment. It refers to the process of inhaling oxygen and expelling carbondioxide from the lungs to the air. It take place in the alveoli.

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.
