1. Identify Patterns The coral reef system simulated in the virtual lab assigns six different groups of organisms to four levels of a food chain. Use the space below, a
separate piece of paper, or a computer application to sketch the food chain. Use
labels to show how the biotic and abiotic factors affect each other. Include notes on
predation and competition.

meiosis is the correct answer

the question isn't complete here so i can't right an answer '_'

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.

1) a

2)c

3)a

4)c

5)b
