supernova: in this stage_
the star collapses and
produces elements heavier
than iron.
planetary nebula: in this
stage, the star emits strong
energy pulses that push
away the outer layers
creating a cloud of ionized
gas around the core.
neutron star: in this
stage, the star has
reduced to an extremely
dense core.
white dwarf: in this stage,
the star has reduced to a
dense core.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

i think it is d. objects resist changes in their state of motion.

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.
