Which of the preceding statements is/are true?A) Helioseismology is the study of the differential rotation and magnetic field of the Sun. B) A filtergram is used to study layers below the photosphere. C) The chromosphere of the Sun has a higher temperature than the photosphere.

A and C

Explanation:

Helioseismology is a branch of science that makes use of  differential rotation and magnetic field to study he structure of the sun.

A filtergram represents the photo of the surface of the sun that is made using high energy particles being accelerated by the sun's magnetic field. Hence, it can only be used to study the surface and not the layers below the photosphere.

The chromosphere of the sun has a temperature between 6,000 °C to about 20,000°C while the photosphere has a temperature between 4,230 and 5,730 °C. Hence, the chromosphere has a higher temperature.

The only true options are A and C.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
