Very few fossils of jellyfish or their close relatives have been found. this makes it hard to trace the evolutionary history of jellyfish using the fossil record. what explains this? a. jellyfish fossils are buried deep under the ocean floor, not in land areas where scientists hunt for fossils. b. jellyfish have soft bodies that decay completely before fossilization can occur. c. jellyfish are a relatively new species in the history of living things on earth and do not have ancient ancestors. d. jellyfish fossils are likely more fragile than other types of fossils and so they degrade before they can be examined.

the answer is c cumulus. cumulus clouds can be seen on a gray and rainy day, because cumulus clouds create thunderstorms. give me brainliest if right.

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.
