Answer:
Briefly ask question please
Answer:
1-false, since its shape is only elliptical
2-true, Large elliptical galaxies often have a system of globular clusters, double nuclei, and large numbers of satellite galaxies. One possible interpretation is galactic cannibalism, that is, the absorption of a smaller galaxy by a larger one - for example, our Milky Way is known to be "digesting" a couple of smaller galaxies today. Therefore they are assimilating or appearing new stars.
3- false, type 2 irregular galaxies are generally new galaxies but the same does not happen with elliptical ones.
4-true, since elliptical galaxies have new and old stars and irregular ones almost all new stars
Explanation:
Types of galaxies. Galaxies have three different configurations: elliptical, spiral, and irregular. A somewhat more specific description, based on its appearance, is provided by the Hubble sequence, proposed in 1936
Answer:
Radioisotopic dating as a new technology has really helped to determine the age of the earth.
Explanation:
The actual age of the earth has been a subject of wanton speculation among different groups of people. Speculations arise from religious, cultural and philosophical perspectives.
However, studies using many radioactive isotopes believed to be present from the origin of the Earth and having extremely long half lives have been most helpful in determining the age of the earth. Radioisotopic dating is a common technique used to determine the age of ancient artifacts. It has shed a great light on the possible age of the earth.
Hence the application of radioisotopic dating as a new technology has really helped to determine the age of the earth.
Probably a small group of researchers because the climate is very harsh.
