What best describes the role of waste during digestion and metabolism? 1. Waste is less likely to leave the body during metabolism and more likely to elave the body during digestion.
2.Waste can be returned from the blood stream to the intestines to be eliminated or released through pores on the skin.
3. Waste is almost never created or removed from the body during the metabolism and digestion processes.
4. Waste is destroyed during the metabolism process, so that there is no waste during the digestion process.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called

a lot of people sadly don't know the best way to learn is cheating off of your friends or this amazing thing called google

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.
