Which of the following is an illustration that protein tertiary structure is not strictly dependent on protein secondary structure and vice versa? which of the following is an illustration that protein tertiary structure is not strictly dependent on protein secondary structure and vice versa? proteins are composed of amino acid monomers. fibrous proteins are dominated primarily by secondary structure and have little to no tertiary structure. globular proteins have both secondary and tertiary structure. globular structures often contain one or more functional domains.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.

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.
