Answer:
A. irregular, B. spiral and D. dwarf elliptical type of galaxy are you likely to observe a significant amount of star formation.
Step-by-step explanation:
You are likely to observe a significant amount of star formation in the following types of galaxies:
A. Irregular: Irregular galaxies do not have a defined shape or structure. They often exhibit ongoing star formation, with young, massive, and hot stars being formed. Irregular galaxies are characterized by irregular patches of gas and dust, which are the fuel for star formation.
B. Spiral: Spiral galaxies have a distinct spiral arm structure and a central bulge. They are known for active star formation occurring in their spiral arms. These arms contain regions of dense gas and dust, where new stars are continuously forming. Spiral galaxies often have a high rate of star formation.
D. Dwarf elliptical: Dwarf elliptical galaxies are small and have a smooth, featureless appearance. While they typically have little ongoing star formation, some dwarf elliptical galaxies can still exhibit low levels of star formation activity. However, the amount of star formation in these galaxies is generally much lower compared to irregular and spiral galaxies.
In summary, the types of galaxies where you are likely to observe a significant amount of star formation are irregular and spiral galaxies. These galaxies have the necessary conditions, such as abundant gas and dust, to support ongoing star formation. While dwarf elliptical galaxies may exhibit some star formation, it is usually at a much lower level compared to irregular and spiral galaxies.
