The mesentery (MESS un tayr ree) is a structure that’s connects the loops of the small intestine l. The mesentery binds the intestines together so it can’t get tangled or twisted. The mesentery also carries blood, nerves signals, and lymph fluids to and from the intestine. Scientists recently classified the mesentery as an organ. What must be true if the mesentery is an organ? Choose the three statements that apply.

A. It is part of an organ system.

B. It has a specific function in the body.

C. It is composed of different kinds of tissues.

D. It is found in every type of multicellular organism.

E. It is a group of similar cells that carry out the same function.

The answer is A.It is part of an organ system.

Explanation:

A bee lands on a random point on a ruler's edge. Find the probability that the point is between 2 and 12.

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.
