The theory of plate tectonics was developed with the contribution of scientists from many different disciplines. what contribution of geophysicists contributed to our understanding of deep-sea ridges and plate tectonics?

a. deep-sea ridges show that life could have evolved along the boundaries of tectonic plates.
b. detritus from dead marine animals on the ocean floor shows that new tectonic plates are constantly being formed.
c. earth's magnetic fields captured in the rock around deep-sea ridges show that fresh magma emerges between tectonic plates.
d. mountain ranges on the ocean floor show that tectonic plates can rise and sink over several hundred million years.

protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.

some choices are:

peanut butter

seeds

eggs

yogurt

meats

fish

so pretty much meat, dairy, nuts, and grains.

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.
